What JPG to WebP does
Re-encodes each JPG as a WebP file at the quality you choose and reports the size change.
When to use it
- Speeding up a website or online shop.
- Meeting a page-weight budget.
- Storing many photos in less space.
Good to know
- At quality 80–85, WebP is typically 25–35% smaller than the JPG with very similar appearance.
- If WebP wouldn’t be smaller, we tell you, and you can keep the original.
- Creating WebP depends on your browser. The tool checks for support before converting, and tells you if this browser can’t create WebP.

- If your browser can’t create WebP, the tool says so before converting.
Frequently asked questions
Do all browsers show WebP?
All current major browsers display WebP, including Safari 14+. Some older apps and email clients don’t.
How much smaller is WebP than JPG?
Usually noticeably smaller at similar quality. In our example, a 1.5 MB landscape JPG became an 820 KB WebP, about 48% smaller, with the same dimensions.
What quality is used?
Quality 92 by default, so the WebP looks the same as the JPG. Lower it for even smaller files.
Can I convert the WebP back to JPG later?
Yes, with WebP to JPG. Each lossy conversion loses a little detail, so keep your original JPG if you might need it again.
