How the math works

  • WebP and AVIF use modern compression and usually beat JPG by 20 to 50 percent at matched quality.
  • JPG quality 80 is a safe default for most photos.
  • PNG is great when you cannot afford any quality loss, but the file will be larger than a WebP at high quality.
  • Quality below 60 starts to show visible artifacts on photographs.
  • If a converted file is larger than the original, the source was already heavily compressed.

FAQ

Is anything uploaded to a server?

No. Conversion happens entirely in your browser using the HTML canvas API. Your images never leave the device and the page does not log file names or contents.

Which formats can it output?

WebP, JPG, and PNG work in every modern browser. AVIF encoding works in recent Chrome and Edge builds. If AVIF is not supported in your browser, the tool will fall back to WebP and tell you.

Is there a maximum file size?

The tool accepts files up to about 25 MB each. Larger files often run into browser memory limits during canvas processing, so they are rejected with a clear message.

Which browsers does it support?

Chrome, Edge, Firefox, and Safari all work for WebP, JPG, and PNG. AVIF output currently requires a recent Chromium based browser. Drag and drop falls back to a file picker on mobile.

What is the difference between lossy and lossless?

WebP, JPG, and AVIF are lossy formats. The quality slider trades file size against image fidelity. PNG is lossless, so the quality slider has no effect when PNG is selected.
