About this tool
WebP is Google's modern image format, and at comparable visual quality it typically produces files 25–35% smaller than JPG. Converting your JPG photos to WebP is one of the easiest ways to speed up a website, improve Core Web Vitals scores and cut bandwidth costs — every major browser has supported WebP since 2020. This free JPG to WebP converter shows the exact size saving per file so you can pick the best quality setting for your needs.
Your photos are converted locally using your browser's built-in WebP encoder — they are never uploaded, stored or logged anywhere. That makes the tool safe for personal photos and client work, and it keeps conversion fast even for large batches. No sign-ups, no watermarks, no limits.
Frequently asked questions
How much smaller will my images get?
For typical photos, WebP at 80–85% quality is around 25–35% smaller than the source JPG at similar visual quality. The exact saving depends on the image content and on how heavily the original JPG was already compressed.
What quality setting should I use?
85% is a good default for photos. Use 90–95% for images you plan to edit further or print, and 60–75% for thumbnails and previews where small size matters more than fine detail.
Do all browsers support WebP?
Viewing WebP works in every modern browser (Chrome, Edge, Firefox, Safari 14+, Opera and mobile browsers). Creating WebP with this tool requires a browser whose canvas can encode WebP — Chrome, Edge, Firefox and Opera can; some versions of Safari cannot, and the tool will tell you if yours can't.
Are my photos uploaded to a server?
No. The whole conversion runs inside your browser using the HTML5 canvas, so your images never leave your device.
