Supported output formats
Convert HEIC or HEIF into any of these ten formats. The size column is measured, not estimated: we ran one real 1440 × 960 HEIC of 287 KB through this exact converter in Chrome at the default quality of 90. Your own results will differ with subject and resolution, but the ranking holds.
| Format | Extension | Compression | Transparency | Sample size | Best for |
|---|---|---|---|---|---|
| JPG | .jpg | Lossy | No | 581 KB | Sharing, email, upload forms, printing — the safest choice anywhere. |
| JPEG | .jpeg | Lossy | No | 581 KB | Identical to JPG. Pick it when a form insists on the four-letter extension. |
| PNG | .png | Lossless | Yes | 3.4 MB | Screenshots, graphics, editing masters, anything needing exact pixels. |
| WEBP | .webp | Both | Yes | 535 KB | Websites and blogs — around 25–35% smaller than JPG at equal quality. |
| AVIF | .avif | Both | Yes | 402 KB | The smallest files. Ideal for performance-focused sites and Core Web Vitals. |
| GIF | .gif | Lossless, 256 colours | Yes (1-bit) | 993 KB | Legacy tools, forum avatars, simple flat graphics. |
| BMP | .bmp | None | No | 4.1 MB | Old Windows software, embedded devices and lab equipment that demands raw bitmaps. |
| TIFF | .tiff | None (lossless) | Yes | 4.1 MB | Print shops, archiving, scanning workflows and publishing. |
| ICO | .ico | Lossless (PNG inside) | Yes | 193 KB | Favicons and Windows application icons — 16, 32, 48 and 256 px in one file. |
| Lossy (JPEG inside) | No | 582 KB | Form submissions, printing, and merging several photos into one document. |
Worth knowing: at the default quality of 90, every full-size format comes out bigger than the HEIC you started with. That is not a fault in the converter — HEIC uses much newer compression than JPG or PNG. AVIF gets closest at 402 KB, about 30% smaller than the JPG for the same visible quality. ICO is smaller only because icons are scaled down to 256 px and below.
Tip: if matching the original size matters, choose AVIF and pull the quality slider back to roughly 70 — that lands near 287 KB, the size of the HEIC itself.
How to convert HEIC to JPG in four steps
-
1
Upload HEIC or HEIF images
Drag files onto the drop area, tap to pick them from your photo library, or paste with Ctrl + V. "Upload" is really the wrong word here: the files are only opened by your browser, never sent anywhere.
-
2
Choose your output format
Pick one of the ten formats. For lossy formats, set the quality slider — 90 keeps photos looking untouched, 80 makes noticeably smaller files.
-
3
Convert instantly
Press Convert images now. Each photo is decoded to raw pixels and re-encoded into your chosen format. A progress bar shows how far along the batch is.
-
4
Download your files
Save each photo with its own button, grab everything as a single ZIP, or — with PDF selected — merge the whole batch into one multi-page document.
What is HEIC?
HEIC is the photo format Apple has used by default since iOS 11 arrived in 2017. The letters stand for High Efficiency Image Container. Inside that container sits an image compressed with HEVC, also called H.265 — the same technology that made 4K video streaming practical.
You will also see the name HEIF, or High Efficiency Image File Format. HEIF is the standard for the container itself — developed by the Moving Picture Experts Group and published as ISO/IEC 23008-12, whose first edition appeared in 2017. HEIC is what you get when that container holds HEVC-compressed pictures, which is what iPhones create. In everyday conversation the two words mean the same thing, and this converter treats them the same way.
Why Apple switched to it
Storage. A HEIC photo is roughly half the size of the same picture as a JPG, with no visible difference. On a 128 GB phone that is thousands of extra photos. When we converted our 287 KB test HEIC to JPG at quality 90, the result was 581 KB — the JPG needed twice the space for the same picture.
How the compression works
JPEG, designed in 1992, breaks an image into 8 × 8 blocks and throws away detail your eye is unlikely to miss. HEVC works on variable-sized blocks up to 64 × 64, predicts each block from its neighbours and only stores the difference. Because photographs contain large areas that are easy to predict — sky, skin, walls — there is far less left to record.
A HEIC container can also do things a JPG simply cannot: store several images in one file (which is how bursts and Live Photos work), keep depth maps for Portrait mode, hold 10-bit colour for smoother gradients, and record edits so they can be undone later.
Image quality
HEIC is still a lossy format, so it does discard information — it is simply much smarter about which information to discard. At matched file sizes HEIC holds more detail than JPG, and 10-bit colour means gentle gradients such as sunsets show less of the banding JPG is known for.
One practical note: converting HEIC to JPG means decoding one lossy format and encoding another, so a second small generation of loss occurs. At quality 90 or above it is invisible in normal viewing. If you need certainty, convert to PNG or TIFF instead — both store the decoded pixels exactly.
Where you will meet HEIC
Every recent iPhone and iPad saves photos this way unless you change a setting, and macOS handles the format natively. Some Android phones, including recent Samsung Galaxy and Google Pixel models, can save HEIF too. The friction almost always appears when photos leave the Apple world — a Windows PC, an older printer, a school portal or a job application form that only accepts JPG or PNG.
HEIC compared with the formats you might convert to
Each of these formats solves a different problem. The tables below say plainly what changes when you convert.
HEIC vs JPG
| HEIC | JPG | |
|---|---|---|
| Introduced | 2017 — standard and iPhone | 1992 |
| File size (same photo) | 287 KB | 581 KB at quality 90 |
| Colour depth | Up to 10-bit | 8-bit |
| Transparency | Yes | No |
| Multiple images per file | Yes | No |
| Opens everywhere | No | Yes |
HEIC wins on technical merit; JPG wins on compatibility. That is exactly why converting is so often the answer.
HEIC vs PNG
| HEIC | PNG | |
|---|---|---|
| Compression | Lossy | Lossless |
| File size (same photo) | 287 KB | 3.4 MB |
| Best subject | Photographs | Screenshots, logos, flat graphics |
| Transparency | Yes | Yes |
| Repeated editing | Loses a little each save | Never degrades |
Choose PNG when exactness matters more than size — a master copy for editing, or an image with transparent areas. For an ordinary holiday photo it is wasteful: ten times the bytes for detail nobody can see.
HEIC vs WEBP
| HEIC | WEBP | |
|---|---|---|
| Created by | MPEG, adopted by Apple | Google, 2010 |
| File size (same photo) | 287 KB | 535 KB at quality 90 |
| Browser support | Safari only | Every current browser |
| Lossless mode | No | Yes |
| Animation | Sequences | Yes |
WebP is the practical web format. It is bigger than HEIC but far smaller than JPG, and — crucially — it displays in every browser your visitors are likely to use.
HEIC vs AVIF
| HEIC | AVIF | |
|---|---|---|
| Underlying codec | HEVC / H.265 | AV1 |
| Licensing | Patent-encumbered | Royalty-free |
| File size (same photo) | 287 KB | 402 KB |
| Browser support | Safari only | Chrome, Edge, Firefox, Safari 16+ |
| Encoding speed | Fast (hardware) | Slower in software |
AVIF is the closest relative to HEIC — both wrap a modern video codec around a still image — and it is the smallest of the ten formats here. In our measurements it matched a quality-90 JPG's visible quality using about 30% fewer bytes. It is royalty-free, which is the main reason browser makers embraced it while leaving HEIC to Apple. Encoding runs in software, so expect roughly a second per photo rather than the instant result JPG gives.
Which format should you choose?
If you are unsure, pick JPG. It is right about eight times out of ten. Use this list when it is not.
- Sending photos to family, or attaching to email
- JPG at quality 85. Small enough for any attachment limit and readable on any device made in the past 25 years.
- Uploading to a government form or job portal
- JPG, or PDF if the form asks for a document. Read the size limit first — many portals cap uploads at 100 KB or 2 MB, so drop the quality slider until you are under it.
- Publishing on a website or blog
- WEBP, or AVIF if speed is your priority. Both cut page weight sharply, which helps Core Web Vitals and mobile visitors.
- Editing later in Photoshop, GIMP or Affinity
- PNG or TIFF. Both are lossless, so you can save repeatedly without the image slowly degrading.
- Sending to a print shop
- TIFF, or high-quality JPG if they ask for it. Keep the full resolution — never upscale a small photo to hit a stated pixel count.
- Making a favicon or app icon
- ICO. You get 16, 32, 48 and 256 px inside one file. Choose a photo whose subject sits in the middle, since icons are centre-cropped to a square.
- Combining receipts or documents you photographed
- PDF with "Merge all photos into one PDF" ticked. Fit to A4 keeps everything printable and consistent.
Best practices worth following
- 1.Keep the originals. Convert copies. Your HEIC files are the smallest, highest-quality version you have.
- 2.Convert once, from the original. Converting a JPG that came from a HEIC adds a third generation of loss for no reason.
- 3.Don't chase quality 100. It inflates the file substantially and adds detail your eye cannot resolve. 90 is plenty.
- 4.Check one photo before a big batch. Convert a single file, open it, confirm it is what you expected, then run the rest.
- 5.Mind your metadata. Conversion strips EXIF, which protects your location — but also removes the date the photo was taken. Keep the HEIC if that matters to you.
Should you keep shooting in HEIC?
An honest look at both sides, so you can decide whether to change your camera setting or simply convert when you need to.
Advantages of HEIC
- About half the file size of JPG at the same visual quality
- 10-bit colour, so gradients and sunsets band far less
- Supports transparency, which JPG cannot
- Holds Live Photos, bursts and Portrait depth maps in one file
- Stores edits non-destructively, so crops can be undone
- Decoded in hardware on Apple devices, so it is fast and battery-friendly
Drawbacks of HEIC
- Windows needs an extra extension, and many apps still refuse it
- No browser except Safari will display a .heic file
- Most upload forms reject it outright
- Older printers, TVs and photo kiosks cannot read it
- Patent licensing keeps support out of some free software
- Sharing with Android or Windows users usually needs a conversion first
Our take: leave your iPhone on High Efficiency and enjoy the storage saving. Convert only the handful of photos that need to travel somewhere else. If you constantly hit compatibility trouble, switch Settings → Camera → Formats to Most Compatible and accept the larger files.
Converting HEIC on your device
On iPhone and iPad
Open this page in Safari or Chrome and tap the drop area to choose photos from your library. iOS decodes HEIC itself, so conversion is quick and the WebAssembly decoder never downloads. Converted files land in your Downloads folder in the Files app, ready to attach or share. To stop new photos being HEIC, go to Settings → Camera → Formats and pick Most Compatible.
On a Mac
Preview and Photos can export HEIC to JPG, but doing a whole folder means clicking through export dialogs. Dragging fifty files onto this page and pressing Convert once is usually faster, and you get formats Preview will not write, such as AVIF, ICO and multi-page PDF.
On Windows 10 and 11
This is where HEIC hurts most. Windows needs the HEIF Image Extensions from the Microsoft Store to show thumbnails, and even then Photoshop, older Office versions and countless upload forms still reject the format. Converting to JPG or PNG sidesteps all of it without installing anything or needing administrator rights — useful on a managed work laptop.
On Android
Recent Samsung and Pixel phones read HEIF, but older devices and many apps do not. If someone AirDropped or emailed you .heic files, open this page in Chrome, select them from your Downloads and convert to JPG. Everything runs on the phone itself, so it works on mobile data without uploading anything.
For photographers, designers and students
Photographers usually want TIFF or PNG to take into Lightroom or Capture One without adding loss. Designers reach for PNG for transparency and ICO for icons. Students submitting coursework almost always need JPG or a merged PDF — and the batch queue plus "Merge all photos into one PDF" turns twenty photographed pages into one file to hand in.
Your photos stay on your device
The short version: most online converters upload your photos to a server, convert them there, and promise to delete them later. Resizo never uploads them at all. There is no server to store your images on, so there is nothing to delete, leak, subpoena or train a model with.
Files are never stored — because they are never sent
Resizo is a static website with no backend that accepts images. When you add a photo, your browser reads it from disk into its own memory. The decoder and encoder run inside the tab. Close the tab and everything is gone from memory; nothing was ever written to anyone's disk.
Nothing to encrypt in transit
Encrypted upload is what a good server-based converter offers, and it matters — but it still means your photo travels across the internet and sits on a machine you do not control. The page itself is served over HTTPS, so the code you run is delivered securely, and your images make no journey at all.
Automatic deletion, by design
There is no retention window to trust, no "files deleted after one hour" policy to take on faith. Your photos live only in the browser tab's memory for as long as it is open. Removing a file from the queue or pressing Clear all releases it immediately.
Location and camera data are removed
Converting decodes your photo to raw pixels and writes a fresh file, so EXIF metadata — GPS coordinates, camera model, serial number, timestamps — does not carry across. If you were about to post a photo of your home publicly, that is a meaningful protection. If you need that metadata, keep the original HEIC.
Browser sandbox security
Conversion runs inside the browser's sandbox, which cannot reach your file system beyond the files you explicitly chose. The HEIC decoder is a WebAssembly module — memory-isolated by design, and unable to make network requests of its own.
Don't take our word for it — check
- Load this page, then turn off your Wi-Fi or enable airplane mode.
- Add a HEIC file and convert it. It still works, because there is nothing to phone home to.
- Or open your browser's developer tools, switch to the Network tab, and watch: no image request is ever made.

Why choose Resizo
There is no shortage of HEIC converters. Here is what is genuinely different about this one.
| Resizo | Typical online converter | Desktop software | |
|---|---|---|---|
| Photos uploaded to a server | Never | Always | No |
| Price | Free | Free tier with limits | Often paid |
| Watermark | None | Sometimes on the free tier | None |
| Daily conversion cap | None | Common (often 10–20/day) | None |
| Installation needed | No | No | Yes, plus admin rights |
| Output formats | 10 | Usually 2–3 | Many |
| Works offline | Yes, after loading | No | Yes |
| Sign-up or email required | No | Frequently | Sometimes |
| Upload wait for large batches | None | Yes, twice — up and down | None |
Ten formats, not two
Most converters give you JPG and PNG. Resizo also writes WebP, AVIF, GIF, BMP, TIFF, ICO and multi-page PDF, all from the same drop area.
Nothing is waiting on a queue
Server converters make you upload, wait behind other users, then download. Converting 30 photos here takes as long as your own processor needs — no round trip.
Honest about the trade-offs
We tell you when a format will make your file bigger, when GIF will hurt a photo, and that conversion strips your metadata. A tool that only lists upsides is hiding something.
Built for real batches
Per-file progress, per-file errors, ZIP download and PDF merging. One unreadable photo reports itself and the rest of the batch carries on.
Accessible and keyboard-friendly
The drop area is focusable, progress is announced to screen readers, and the whole page works in dark mode.
Part of a full toolkit
Once converted, resize, compress, crop, rename or watermark your photos with the same privacy promise. No new account anywhere.
Troubleshooting
"No image found inside this file"
The file is probably the video half of a Live Photo (a .mov) rather than the picture, or the copy from your phone was interrupted. Copy it across again and retry.
A large batch stalls or the tab reloads
Conversion uses your device's memory, and a 48 MP photo needs a lot of it. Close other tabs and convert in groups of ten. Phones with 3 GB of RAM or less should work in smaller batches.
AVIF is slow
Expected. AVIF encoding is computationally heavy and runs in software, so allow a few seconds per photo. The encoder also downloads once on first use. If you only need small files quickly, WebP is a good compromise.
My photo came out rotated
Rare, but possible with unusual rotation metadata. Open the converted file in any editor and rotate it back, or convert the original again after opening and re-saving it in Photos.
The GIF looks speckled
GIF allows only 256 colours, so photographs are dithered — scattered dots that trade a little noise for smooth-looking gradients. It is the best GIF can do. For a clean photograph, use PNG or WebP.
Nothing happens when I add files
Check that JavaScript is enabled and that no content blocker is stopping the page's scripts. The converter is the page's code — with scripts blocked there is no server-side fallback to fall back to.
Frequently asked questions
What is a HEIC file?
HEIC is the file format Apple uses for photos taken on an iPhone or iPad. It stands for High Efficiency Image Container and it stores an image compressed with HEVC. A HEIC photo is usually about half the size of the same photo saved as JPG, at the same visual quality.
How do I convert HEIC to JPG for free?
Open the converter at the top of this page, drag your .heic files in, choose JPG as the output format and press Convert. The files are converted on your own device and you can download them straight away. No charge, no sign-up, no watermark.
Are my photos uploaded to a server?
No. Resizo has no backend that receives images. The decoder and encoders run inside your browser tab, so your photos stay on your device from beginning to end. You can verify it by opening your browser's Network tab while converting, or by disconnecting from the internet after the page has loaded.
Will converting HEIC to JPG reduce quality?
There is a small, usually invisible loss, because both HEIC and JPG are lossy formats. At quality 90 you will not see a difference on screen or in print. If you want a mathematically exact copy of the decoded image, choose PNG or TIFF instead — both are lossless.
Can I convert several HEIC photos at once?
Yes. Add up to 60 photos in one batch, convert them in a single pass and download the results together as a ZIP file. With PDF selected you can also merge every photo into one multi-page document.
Why won't my HEIC files open on Windows?
Windows 10 and 11 need the HEIF Image Extensions from the Microsoft Store to display HEIC files, and many applications and upload forms still refuse them even after that. Converting to JPG or PNG removes the problem entirely, because every program on Windows can read those two formats.
How do I stop my iPhone from creating HEIC files?
Open Settings, tap Camera, then Formats, and choose Most Compatible. New photos will be saved as JPG. Photos you have already taken stay in HEIC, so you will still need a converter for your existing library.
What is the difference between HEIC and HEIF?
HEIF is the container standard. HEIC is the common case of that container holding an image compressed with HEVC, which is what Apple devices produce. In everyday use the two words are interchangeable, and this converter accepts .heic, .heif and .hif files alike.
Which format should I choose — JPG, PNG or WebP?
Choose JPG for photos you need to share, email or upload to a form, because everything accepts it. Choose PNG when you need a lossless copy or transparency. Choose WebP for websites, where it is roughly 25 to 35 percent smaller than JPG at the same quality.
Can I convert HEIC to PDF?
Yes. Select PDF as the output format. Each photo becomes a page, and you can either fit every image to A4 for printing and form submissions or make each page exactly the size of the image. Several photos can be merged into one document.
Does the converter add a watermark?
No. Resizo never adds a watermark, a logo or a filename suffix. The converted file contains only your image.
Is there a file size or file count limit?
Each file can be up to 60 MB and you can queue up to 60 files per batch. These limits exist because conversion uses your device's own memory, not because of a paid tier. Older phones will be happier with smaller batches.
Does it work on iPhone and iPad?
Yes. Open the page in Safari or Chrome on iOS or iPadOS and choose photos straight from your library. Apple devices decode HEIC natively, so conversion is especially fast and the WebAssembly decoder is never downloaded.
Does the HEIC converter work offline?
Once the page and the decoder have loaded, conversion itself needs no connection. You can switch on airplane mode and keep converting, which is a useful way to prove that nothing is being sent anywhere.
What happens to the EXIF and GPS data in my photos?
Conversion decodes your photo to raw pixels and re-encodes it, so EXIF metadata including GPS coordinates, camera model and timestamps is not carried over. That is good for privacy. If you need to keep the original metadata, keep a copy of the untouched HEIC file.
Can I convert HEIC to ICO for a favicon?
Yes. Choose ICO and Resizo centre-crops the photo to a square and writes 16, 32, 48 and 256 pixel versions into a single .ico file, which is what browsers and Windows expect from an icon.
Why is my converted JPG larger than the original HEIC?
That is expected. HEVC compression inside HEIC is far more efficient than JPEG's, so the same picture needs roughly twice the bytes as a JPG. In our test a 287 KB HEIC became a 581 KB JPG at quality 90. Lower the quality slider to about 80 if file size matters more than fine detail.
Can I convert Live Photos or burst HEIC files?
The still image is converted. A Live Photo is a still plus a short video, and only the still frame can become a JPG or PNG. For files holding several images, Resizo converts the primary image — the one your phone shows as the photo.
What should I do if a HEIC file fails to convert?
First check that the file really is an image and not the .mov half of a Live Photo. Damaged or partially copied files cannot be decoded, so try copying it from your phone again. If a very large photo fails, close other tabs to free memory and convert fewer files at a time.
Is Resizo's HEIC converter really free?
Yes — no trial, no credit card, no daily conversion cap and no paid tier holding features back. The site is funded by advertising, which is why there is no need to charge for conversions or to process your files on a server.
