What this does
Compress WebP images, or turn a mixed set into WebP: the desk starts at quality 80 with transparency kept, and lossless WebP is one switch away in the Recipe panel. The honest limit: this uses your browser’s WebP encoder, so Safari cannot write WebP here and its rows say so.
When to use this, and when not
- Use it for WebP files from websites, or to make a set of photos smaller than JPEG at the same look.
- For a website, compress images for website also caps the long edge and removes capture information.
- If the files go to someone with older software, JPEG opens everywhere; WebP does not.
Honest limits
- No separate alpha quality: the transparency is encoded at the same quality as the colour.
- Capture information is not carried into a WebP in this build; the row says so.
- No DPI is written into WebP files.

Questions
Lossy or lossless WebP?
Lossy (the default here, quality 80) is for photographs and is usually far smaller. Lossless keeps every pixel and suits graphics and screenshots; switch it on under Colour and density in the Recipe panel. A lossless file is decoded again and compared pixel for pixel before its row says lossless.
Does it work in Safari?
Safari can open WebP but its canvas cannot write it. In Safari each file is left alone with that reason on its row; choose JPEG or PNG as the format there, or use Chrome, Edge or Firefox.
Is transparency kept?
Yes, in both lossy and lossless WebP. It is only flattened if you choose JPEG as the format.
Can I convert WebP to JPEG or PNG here?
Yes: choose JPEG or PNG on the recipe bar. Every row says the format it was written as, and the extension in the ZIP changes with it.
