About this tool
WebP's predictive compression usually beats JPG by a wide margin at the same visual quality. Convert a batch with one quality setting and compare exact before/after sizes before you download.
How to use the JPG to WebP tool
- Add JPG files. Drop .jpg or .jpeg photos into the area below.
- Tune quality. 80% is a solid default; lower for aggressive savings, higher for archival copies.
- Convert and compare. Each result shows its original and final size; download individually or as a ZIP.
Supported formats
Input
- JPEG (.jpg, .jpeg)
Output
- WebP (image/webp)
Inputs are validated before anything is processed. Invalid values and unsupported files are rejected with a clear error instead of failing silently.
Frequently asked questions
How much smaller will it be?
Photographs commonly shrink 25–40% at quality 80, sometimes more. Flat graphics may already be close to optimal as JPG.
Does WebP work everywhere now?
Safari 14+, and every current Chrome, Edge and Firefox. Very old browsers still need a JPG fallback.
Is the conversion lossy?
Yes. Both formats are lossy; converting adds one more generation, so keep the original.
Is there metadata in the output?
No. Canvas re-encoding produces clean files without EXIF.
Privacy
Encoding happens locally; the site never receives your images.
No account is required and no file is ever uploaded. See the privacy policy for details about analytics and the limited data this site stores.
Known limitations
- Lossless WebP is not available through browser APIs, so encoding is always lossy.
- Extremely large images are limited by browser canvas dimensions.
- Animated formats export the first frame only.
