Convert JPG to WebP

WebP usually stores the same photo in fewer bytes than JPG, so web pages load faster. Convert here and see the exact saving for your own image, on your device and without uploading it.

Why convert to WebP

All current versions of Chrome, Edge, Firefox and Safari display WebP. Smaller images mean faster pages, which matters for your own website, blog or online shop.

WebP is for publishing on the web. If you are sending a photo to someone or uploading it to a form, keep the JPG: some apps and forms still don’t accept WebP.

How the conversion works

  1. Your browser decodes the JPG, applying the EXIF orientation.
  2. It re-encodes the pixels as WebP at 85% quality, or at the highest quality that fits a size target you choose.
  3. The result panel shows the new size and how much smaller it is than the original. EXIF metadata such as GPS location is not copied.

Measured on two real photos

  • Phone photo: garden (4032 × 3024, original JPG saved at about quality 94): 7.15 MB → 4.40 MB as WebP, 38.6% smaller.
  • Camera photo: cake (5536 × 3766, original JPG saved at about quality 99): 10.19 MB → 1.67 MB as WebP, 83.7% smaller.

Why the savings differ so much

How much you save depends mostly on how the original JPG was saved. The cake photo was stored at almost maximum JPG quality, so re-encoding at 85% drops a lot of detail you can’t see. A typical phone JPG, around quality 90–95, saves less. Both were converted with this tool in Chromium 156.0.8078.4 at full size. Your own saving is shown right after converting.

Browser support for creating WebP

Creating WebP files needs a browser that can encode WebP, such as current Chrome, Edge or Firefox. If your browser can’t, this page tells you up front instead of silently saving another format.

Frequently asked questions

Is my photo uploaded?

No. Decoding and encoding both happen in your browser’s memory, and the WebP is handed to you as a download. There is no upload endpoint.

How much smaller will my image be?

It depends on the photo. In our two measured examples the WebP was 39% and 84% smaller, and the big difference came from how the original JPG had been saved. The tool shows the exact saving for your file after converting.

Will the quality drop?

Both formats are lossy, so re-encoding always changes some pixels. At 85% WebP quality the differences are hard to see at normal viewing size. Check the preview before you use the file.

Can I convert PNG files too?

Yes, PNG files are accepted here as well. For PNGs with transparent backgrounds, the PNG to WebP page explains how transparency is kept.
