    Questions

    Why convert JPG to WebP?

    WebP usually needs fewer bytes than JPG for the same visual quality, so pages load faster. Google’s own comparison found WebP files 25 to 34% smaller than JPG at equal quality. Every current browser displays WebP.

    Will every file get smaller?

    Not always. If the JPG was already heavily compressed, re-encoding it may not save much, and at a high quality setting it can even grow. Each file shows its size before and after, so you can keep whichever is better.

    Which quality should I pick?

    85 is a good default for photos on websites. Go lower (70 to 80) for thumbnails, higher (90+) for photos people will zoom into. To hit an exact file size, use the image compressor.

    Does it work on iPhone and in Safari?

    Yes. Chrome, Edge and Firefox write WebP themselves. Safari, and every browser on iPhone and iPad, can’t, so a WebP encoder (libwebp, about 110 KB) downloads once and does it on your device.

    How many photos can I do at once?

    Up to 20 files per batch, up to 50 MB each and 200 MB in total. Files are processed one after another; download each one as soon as it is ready, or all of them as a ZIP.

    Very large images are refused to keep your browser from running out of memory: above 100 megapixels on computers and 50 megapixels on phones and tablets. On iPhone and iPad, formats other than HEIC are limited to about 16 megapixels by Safari.

    Is it free? Do I need an account?

    It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
