JPG to WebP Converter
To convert JPG to WebP, add one photo or a batch, choose a quality — 80 suits most photographs — and check the saving reported for each file. WebP is typically 25–35% smaller at the same visual quality. Camera metadata such as location is not carried across. Keep the original JPG as your master. Nothing is uploaded.

How it works
WebP uses a more modern compression method than JPG, which is why it lands 25-35% smaller at a matched visual quality. On a page of photographs that is the difference between a fast load and a slow one, especially on a phone connection.
Converting is re-encoding, not recovery: any detail the original JPG already discarded is gone for good, and compressing twice always costs a little more. Convert from the largest original you still have rather than from a copy that has been through several rounds.
JPG has no transparency, so nothing is lost on that front. Photographs with fine grain or heavy texture compress least well in any format — those are the ones worth checking at full size before publishing.
Images are decoded by the browser, redrawn on a canvas and re-encoded on your own machine. Nothing is uploaded, so there is no waiting on a queue and no copy of your photos anywhere else.
Tips and common mistakes
- Start at quality 80 and compare at full size; raise it only if you see a difference.
- Convert from your original JPGs rather than from copies that have already been compressed.
- Check heavily textured photos — grass, gravel, fabric — which compress least well in any format.
- Keep the JPGs as masters and publish the WebP files.
