About converting JPG to WebP
WebP typically produces a noticeably smaller file than JPG at a comparable visual quality, which matters for web pages where every kilobyte affects load time — this tool converts a JPG to WebP to take advantage of that.
The image is decoded and re-encoded as WebP on a canvas at your chosen quality, entirely in your browser. WebP support is now broad across modern browsers, though it's worth checking compatibility if the image needs to work in an older or more unusual environment.
Supported files
Accepts JPG images. Produces a .webp image.
Is my file uploaded?
No. The JPG is decoded and re-encoded as WebP entirely in your browser on a canvas — it's never uploaded.

JPG to WebP — frequently asked questions
How much smaller is WebP?+
Usually 25–35% smaller than a JPG at the same visible quality, which is why it's popular for websites.
Do all browsers support WebP?+
All current browsers do. Very old software may not — keep a JPG copy if you need maximum compatibility.
Is there a free way to convert JPG to WebP for a smaller file?+
Yes — this tool decodes and re-encodes the JPG as WebP entirely in your browser, free and with nothing uploaded.
Can I control the WebP quality?+
Yes — a quality slider lets you trade file size against visible compression before downloading.
Do you upload my files to a server?+
No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.
Is there a file size limit?+
There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
