Convert JPEG images to WebP straight in your browser, one at a time or all at once. No file is uploaded anywhere: your own computer does the decoding and the encoding, which is why the conversion is instant and there is no size limit.
Recompressing a JPEG is never free, but WebP is efficient enough that the trade still comes out ahead: at the same perceived quality the file usually lands a third smaller.
JPEG is the photographic format everyone has, with lossy compression and universal support. The trade-off is that it has no transparency and degrades a little every time it is saved again. WebP, on the other hand, is the recommended format for the web since 2020: transparency, lossy and lossless modes, and 25 to 35 % less weight than an equivalent JPEG, although older desktop software still does not always open it.
How to use it
- Drag the images onto the area above, or click to pick them.
- Choose the target format and, where it applies, the quality.
- Press “Process” and download the results one by one or together as a ZIP.
Frequently asked questions
- Is quality lost going from JPEG to WebP?
- WebP compresses with loss, so yes, a little — controlled by the quality slider. At 80-85 the difference does not show on a screen. Always start from the original so recompressions do not stack up.
- What happens to transparency?
- JPEG has no transparency, so there is nothing to keep: the result will be opaque either way.
- Can I convert a lot at once?
- Yes. Drop in as many files as you like: they are processed in parallel across every core your processor has, and you can download them together as a ZIP.
- Are the images sent to a server?
- No. Everything happens inside this tab. Once the page has loaded you can disconnect from the network and carry on converting.
