jpg → webp
Convert JPG and JPEG to WEBP and shrink your photos by up to 80%.
Every photograph starts as a JPG or PNG, and every website gets faster when those become WEBP. This converter re-encodes JPG and JPEG files into WEBP using your browser’s native encoder — the same implementation Chrome uses — giving you a genuine 50–80% size reduction on typical photographs with no visible quality loss at the default setting.
100% client-side — your files never leave your device
Conversion runs locally in your browser using Canvas and WebAssembly. There is no upload step, no server processing and no file storage. Disconnect from the internet and this page still works.

High quality — Lower values make a smaller file, higher values keep more detail.
Step by step
Drag and drop your file into the box above, or click it to browse your device. Add several at once and they convert together as a batch.
Drag the webp quality slider to trade file size against fidelity. Around 85% is visually indistinguishable from the original; lower values shrink the file further.
Click Download to save the result straight to your device. The whole process took a fraction of a second because nothing was uploaded or downloaded.
Side by side
Here is how the two formats differ. Use it to decide whether converting is worth it, and which one to pick if you have a choice.
| Attribute | JPG.jpg | WEBP.webp |
|---|---|---|
| Full name | JPG (Joint Photographic Experts Group) | WEBP (Google WebP) |
| Compression | Lossy | Lossy or Lossless |
| Transparency | No | Yes |
| Browser support | Universal | Modern |
| Typical file size | 1.1 MB | 260 KB |
| Best for | Photography and general-purpose images | Web publishing and fast page loads |
The guide
Both use perceptual, lossy compression, but WEBP’s encoder is roughly 25–35% more efficient at the same perceived quality. That means a 1 MB photo becomes roughly 700 KB at an identical quality setting, or the same 700 KB at a visibly higher quality. The practical effect is faster Largest Contentful Paint, less mobile data used, and lower bounce rates — which is why every major CDN now transcodes to WEBP by default.
Start at the default 0.85. If you are publishing a portfolio where visitors may zoom in, use 0.9 or 0.95. If the images are thumbnails, backgrounds, or behind a further lossy pipeline such as Instagram, 0.7 to 0.75 is plenty. For JPG sources there is a second ceiling worth knowing: re-encoding a JPG cannot restore detail that the original JPG already discarded, so going above 0.9 mostly just inflates the file.
Canvas-based re-encoding drops EXIF data entirely, including camera model, exposure settings, GPS coordinates and timestamps. That is a privacy benefit for anything you publish, but it does mean the output will not preserve the original capture information. Keep your unedited JPG as an archive if you need that metadata to survive.
