About this tool
Conversion happens in the page: the JPG file is decoded by your browser, redrawn, and re-encoded as WEBP. Nothing is uploaded, so there is no queue, no size limit imposed by a server, and no copy of your image on someone else's machine.
WebP is typically 25–35% smaller than JPEG at matching quality, and every current browser displays it.
The image's pixel dimensions are unchanged — only the format and file size differ. To change the size as well, use the image resizer afterwards.
Common uses
- Sending an image to software that will not accept JPG.
- Reducing the file size of a JPG image.
- Standardising a set of images on one format.
Frequently asked questions
- Is my JPG file uploaded?
- No. It is decoded and re-encoded by your browser on your device, which is why there is no wait and no size cap.
- Does converting JPG to WEBP lose quality?
- Slightly, since the output format is lossy. At 90% quality the difference is rarely visible at normal viewing size.
- Are the dimensions changed?
- No. The image keeps its pixel dimensions; only the encoding changes. Use the image resizer to change dimensions.
