About the JPG to WebP converter

JPG is best for photos — small files and universal support, but no transparency and some quality loss each time it is saved. WebP is best for websites — usually 25–35% smaller than JPG at similar quality, with transparency support.

Switching website photos from JPG to WebP reduces page weight, which helps loading speed and Core Web Vitals. At 80–85% quality, the difference is rarely visible.

Keep your original JPGs as masters; re-saving lossy files repeatedly slowly reduces quality.

How to use it

  1. Drop your JPG files on the box above, click “Choose files”, or paste an image.
  2. Check the output format is WebP and set the quality (85–92% is a good balance).
  3. Click “Convert to WebP”.
  4. Download each image, or use “Download all”.

Frequently asked questions

Are my images uploaded to a server?

No. The conversion uses your browser’s built-in image engine, so the files stay on your device. That also makes it fast — there is no upload or download wait.

How much smaller will my images be?

Commonly 25–35% smaller than JPG at similar visual quality, sometimes more. The exact saving depends on the photo.

Do all browsers show WebP?

All current versions of Chrome, Safari, Firefox and Edge support WebP.

Can I convert several files at once?

Yes. Add up to 30 images and convert them in one go, then download them individually or all together.
