## Capabilities

- Free: Yes, with no watermark and no page limit.
- Account required: No. There is no account system.
- Processed on device: Yes. The file is read by your browser and never uploaded. There is no server to send it to.
- Formats: JPG in. WebP out, one file per image, or a ZIP when you convert several.
- Limits: No image count limit. Both formats are lossy, so a JPG that has already been squeezed can come out no smaller, or larger. The measured size is shown before you download.
- Mobile: Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
- Offline: Yes, after you have used it once. Your browser keeps what the tool needs, so it then works with no network connection.

## Questions

### Will the WebP definitely be smaller than my JPG?

Not always. WebP compresses better than JPG from the same original, but your JPG is not an original: it has already been through one lossy pass, and re-encoding cannot undo that. A lightly compressed JPG usually shrinks. One that was already squeezed for email can come out the same size or bigger. The result is measured and shown before you download, so you can keep the original when it wins.

### How much quality does this cost?

A little. Two lossy formats in a row means a second approximation over data that was already approximated once, so fine texture and hard edges soften slightly. A higher quality setting reduces it and costs file size. Nothing avoids it entirely, because the JPG cannot be un-compressed first.

### Does my photo get a transparent background?

No. WebP supports transparency and a JPG has none to carry across, so the result is fully opaque. Changing the format cannot add an alpha channel that was never there.

### Should I convert my whole photo library?

No. WebP is a delivery format. Converting a library re-compresses every file for a saving you may not get, and leaves you with images some desktop tools still refuse. Convert the copies that go on a web page and keep the originals.

### What happens to the photo's EXIF data?

It is dropped. The WebP is written from decoded pixels, and the camera model, capture time and location tags are not carried across. The orientation flag is applied before writing, so the WebP is upright.
