TinyPNG has been the go-to image compression tool for millions of web developers since 2012. It's fast, well-known, and produces solid results. But it works by uploading your files to their servers — which means your images leave your device every time you use it.

Kordu's Image Compressor takes a different approach: compression runs entirely in your browser using the Canvas API. Your files never leave your device, there are no session limits on the free tier, and you don't need an account. For anyone who handles sensitive images — client photos, confidential screenshots, product designs — the privacy difference matters.

Both tools produce comparable output quality for typical PNG and JPEG compression. Here's how they compare across the factors that matter most.

Our verdict

Bottom line

For most users, Kordu's Image Compressor is the stronger choice: completely free, no file count limits, and processes everything locally in your browser. Kordu now supports eight output formats including AVIF and APNG, matching TinyPNG's key format advantages. TinyPNG retains an edge for JPEG XL output and its API for automated pipelines. For privacy-conscious use or high-volume compression without a subscription, Kordu wins.

Frequently asked questions

Does TinyPNG upload my files to its servers?

Yes. TinyPNG compresses images server-side and retains uploaded files for up to 48 hours before permanently deleting them. Kordu's Image Compressor runs entirely in your browser — nothing is uploaded.

Is TinyPNG free to use?

TinyPNG offers a free tier limited to 20 images per session with a 5 MB file size cap. Paid plans (Web Pro at $39/year, Web Ultra at $149/year) remove these limits. Kordu is free with no session limits and supports files up to 500 MB.

Which compresses better — TinyPNG or Kordu?

Both produce high-quality results for PNG and JPEG compression. TinyPNG uses proprietary server-side algorithms; Kordu uses the browser's Canvas API. For typical web images, the difference in output file size is minimal.

Does Kordu support the same formats as TinyPNG?

Kordu now matches TinyPNG on AVIF and APNG, and adds GIF, BMP, and ICO output that TinyPNG lacks. TinyPNG still supports JPEG XL which Kordu doesn't yet. Kordu also accepts a wider range of input formats including HEIC/HEIF, SVG, TIFF, BMP, and ICO.
