How it works

  • Your images never leave your device — all processing happens in your browser
  • HEIC: iPhone photo format, decoded locally in your browser. Support depends on your browser (tested in Chrome and Firefox); you'll see an error if a photo can't be decoded
  • JPG: Best for photographs, opens everywhere, no transparency
  • WebP: Modern format, 25-35% smaller than JPG, supports transparency
  • PNG: Lossless compression, supports transparency, larger files

Frequently asked questions

Is transparency kept when converting PNG to WebP?

Yes. WebP supports an alpha channel, so transparent areas stay transparent.

Is WebP always smaller than PNG?

For photos and detailed images, almost always. For tiny icons with a few flat colors, the saving can be small.

Are my photos uploaded to a server?

No. The conversion runs entirely in your browser. Your files never leave your device, and nothing is stored or logged.
