# eCommerce Image Resizer Documentation

Resizo's **eCommerce Image Resizer** turns one product photo into every marketplace-ready size in a single pass — 63 verified 2026 presets across Amazon, Etsy, Shopify, eBay, Flipkart, Meesho, Myntra, and WooCommerce — with focal-point cropping, cover/contain modes, white-background flattening, and JPG, PNG, or WebP output. Everything runs in the browser; product photos are never uploaded.

- **Live tool:** https://www.resizo.in/ecommerce-image-resizer/
- **Presets:** 63 across 8 platforms (Amazon 13, Etsy 8, Shopify 9, eBay 6, Flipkart 8, Meesho 6, Myntra 7, WooCommerce 6)
- **Export formats:** JPG, PNG, WebP (PNG-only presets such as logos and icons always export as PNG to preserve transparency)
- **Batch export:** Multi-select presets → one ZIP grouped into a folder per platform; multiple source images can be batch-exported in every selected size
- **Privacy:** 100% client-side. Images are decoded with browser APIs, resized on an HTML5 `<canvas>`, and downloaded straight from memory. Nothing is uploaded to Resizo, stored, or inspected.
- **Price:** Free. No account, no email, no watermark.

## How it works (4 steps)

1. **Upload a product image.** Drop, browse, or paste a photo. It is decoded locally in your browser — no upload, no queue.
2. **Select presets.** Tick any presets across the eight platforms, or use the per-platform *All* toggle. Search by name, size (e.g. `1000`), or platform.
3. **Set crop focus & adjust.** In *Cover* mode, choose the crop-focus point so the right part of the photo stays in frame, then tune background, padding, filters, and watermark.
4. **Export as ZIP.** Download the focused preset, or export every selected size as a ZIP grouped by platform. Images never leave your device.

## Crop modes

- **Cover** — fills the entire target canvas at the preset's exact aspect ratio, cropping overflow. Use the **crop-focus marker** to choose which part of the photo stays centered. Best when the final marketplace slot must be completely filled (most product thumbnails and heroes).
- **Contain** — fits the whole source image inside the canvas with padding/letterboxing on a chosen background. Use when nothing may be cropped (size charts, infographics, wide banners).

## White-background presets

Marketplace *main images* on Amazon, Flipkart, Meesho, Myntra, eBay, Shopify, and WooCommerce generally require a **pure-white (#FFFFFF) background**. Presets flagged **White (required)** in the tables below automatically flatten transparency onto pure white. If you export one of these as JPG, transparency is flattened to white automatically (JPG cannot store an alpha channel); choose PNG or WebP to keep transparent cutouts.

The tool applies the exact dimensions, formats, and background rules below, and processes every export locally in the browser.

## Format guidance

- **JPG** — best for white-background marketplace listings; quality ~85–90 balances clarity and file size. Cannot store transparency.
- **PNG** — best for logos, icons, infographics, and size charts where text must stay crisp or transparency must be preserved.
- **WebP** — smallest files at equivalent quality; supported by all modern marketplaces that auto-serve WebP (e.g. Shopify). Preserves transparency.

## Developer & integration notes

- **No backend, no API key.** The tool is a static page; all resizing happens client-side via the Canvas API. There is no server endpoint to call and no rate limit.
- **Privacy by architecture.** Because decoding and resizing happen in-browser, product photos never traverse the network — a compliance-friendly default for brands handling unreleased product imagery.
- **Embed it.** Any Resizo tool can be embedded as an iframe — see the [Embed Generator](https://www.resizo.in/embed/) and [Embed Documentation](https://www.resizo.in/embed/docs/) for URL parameters, theming, and auto-resize.
- **Structured data.** The live page exposes `SoftwareApplication`, `HowTo`, `FAQPage`, and `BreadcrumbList` JSON-LD for rich results and AI answer engines.

## Frequently asked questions

**Does this resizer upload product photos?** No. Images are processed locally in your browser with the Canvas API — not uploaded, stored, or inspected.

**Which platforms are supported?** 63 presets across Amazon, Etsy, Shopify, eBay, Flipkart, Meesho, Myntra, and WooCommerce.

**What size should Amazon product images be?** At least 1000 × 1000 px (enables zoom); 2000 × 2000 px recommended, pure white background, product ~85% of the frame.

**What size should Meesho product images be?** Square 1:1 at 1000 × 1000 px (500 × 500 minimum), pure white background, under 5 MB, no logos/watermarks/text on the main image.

**What size should Myntra product images be?** 3:4 portrait, typically 1500 × 2000 px on a pure-white background, exported as JPEG in sRGB.

**Can I resize for several platforms at once?** Yes — select any number of presets and download them all in one ZIP organised by platform. Several product photos can also be batch-exported.

**How does the crop focus point work?** In Cover mode each preset crops to its exact aspect ratio; the crop-focus marker chooses which part stays centered.

**Which formats can I export?** PNG, JPG, or WebP. JPG suits white-background listings; PNG and WebP preserve transparency.

**What happens if I export JPG with a transparent background?** JPG cannot store transparency, so the export is flattened onto white. Use PNG or WebP for transparent cutouts.

**Is there a watermark or signup?** No. Resizo is free with no account, no email, and no watermark on exports.

## Notes

- Use **cover** mode when the marketplace slot must be filled exactly; use **contain** when the whole image must remain visible.
- Keep the product centered for cover-mode crops so it survives every aspect ratio.
- For marketplace main images, export JPG at quality ~85–90 on a pure-white background.
- PNG-only presets (logos, icons, size charts) always export as PNG so transparency and text stay crisp.
