PNG to WebP: common questions
Does converting PNG to WebP lose quality?
Transparency is kept. At 92% quality the WebP is lossy: almost invisible on photos; with very fine text, compare before replacing the original.
How many files can I convert at once?
Up to 10 still JPG, PNG, WebP or AVIF images at once, up to 30 MB and 40 megapixels each, with single or ZIP download. AVIF requires a compatible browser.
Does it work on a phone?
Yes, in current mobile browsers (Chrome, Safari, Edge, Firefox). Large files take a little longer on a phone, and the tab should stay open until the download is ready.
Are my files uploaded to a server?
No. The conversion happens inside your browser: the file is read and processed on your device and is not sent to Cocuyo or to any third party. You can check it in your browser’s network tools: your file is not sent.
Is it really free?
Yes. You can try it before signing up; to download the result we ask for a free account, with no subscription. Your free account comes with 30 welcome uses; after that, each use costs 1 credit (top-ups from US$1), and they are unlimited with Basic or Pro. It never adds a watermark.
