Resizo vs TinyPNG: Which Image Tool Should You Use?

TinyPNG is one of the most recognized names in image compression. Resizo is a privacy-first image resizer that also handles compression. While they overlap on compression, they take completely different approaches to processing, limits, and privacy.

Quick Verdict

Choose Resizo if you need resizing + compression in one step, want zero file limits, and care about privacy. Choose TinyPNG if you only need lossy PNG/JPEG compression and prefer a minimal drag-and-drop interface with no other controls.

Feature Comparison Table

Feature data verified from public websites as of April 2026.

Privacy and Security

Resizo processes images entirely in your browser using the HTML5 Canvas API. No data is transmitted to any server. When you close the tab, the image is gone from memory.

TinyPNG uploads every image to its servers for compression. Files are stored on its infrastructure during processing. TinyPNG states that it deletes uploaded files, but the transmission itself is a privacy exposure for sensitive images.

Compression Quality

TinyPNG uses proprietary lossy compression algorithms optimized specifically for PNG and JPEG files. It applies smart quantization to reduce colors while maintaining visual quality. The compression is automatic — you cannot adjust the level.

Resizo uses the browser's built-in Canvas API compression with an adjustable quality slider. For JPG and WebP, you control the exact compression level. PNG output is lossless. This gives you more control over the quality-vs-size tradeoff.

Resize vs Compress

A key difference: TinyPNG only compresses. It does not resize images. If you need to change dimensions and compress, you need two separate tools.

Resizo does both — resize and compress in a single step. Set your target dimensions, choose your output format and quality, and download. One tool, one step.

File Limits

TinyPNG's free tier is limited to 20 images per batch and 5 MB per file. Exceeding either limit requires a TinyPNG Pro subscription ($39/year as of April 2026).

Resizo has no limits at all — no file count limit, no file size limit, no daily quota. This is possible because processing happens on your device, not on a paid server.

Developer API

TinyPNG offers a paid API for automated compression in build pipelines and CMS integrations. This is a genuine advantage for developers who need programmatic compression.

Resizo does not offer an API — it is a browser-based tool designed for direct use.

When to Choose Resizo

• You need to resize and compress in one step
• You want no file limits (count or size)
• You want control over compression quality
• You need format conversion (e.g., PNG to WebP)
• Privacy matters — your images never leave your device
• You want a live preview before downloading

When to Choose TinyPNG

• You only need compression (no resizing)
• You want automatic optimization without manual quality settings
• You need a developer API for build pipelines
• You use the Photoshop/Sketch plugin for in-editor compression
