- Formats: JPG, PNG, WebP, GIF, BMP, AVIF and ICO in. JPG, PNG or WebP out, your choice, the same for the whole batch.

- Offline: Yes, once the page has loaded. The tool keeps working with no network connection.

## Questions

### Which format should I pick?

JPG for photographs going anywhere at all, because everything opens it and it is the smallest of the three on a photograph. PNG when the image has transparency or is a screenshot, diagram or logo, where its lossless compression is both smaller and sharper than JPG. WebP when the destination is a website you control and you want both.

### Can I convert a whole folder at once?

Yes, and there is no count limit. Drop them all in, pick one output format for the batch, and they come back as a ZIP with each file named after the one it came from. Anything that fails is listed separately with the reason rather than silently dropped, and what succeeded is still there to save.

### Why is there no AVIF, TIFF or HEIC output?

Because a browser cannot write them. Measured in Chrome: asking a canvas for AVIF returns a PNG with an AVIF file extension, which is worse than a refusal because it looks like it worked. HEIC and TIFF are the same story. They can all be read here and turned into one of the three, and the dedicated pages for those inputs say so on their own terms.

### Does converting lose quality?

Going to PNG or WebP lossless, no. Going to JPG, yes, once, because JPG is a lossy format and this is a fresh encode. Converting a JPG to a JPG loses a second generation, which is why /jpeg-to-jpg exists to rename rather than re-encode when the file was already one.
