Before you convert

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.

Why are some conversions missing?

We only publish a page when the conversion really works in the browser. HEIC photos convert to JPG and PNG with your browser’s own decoder; Word or Excel are not here yet. AVIF to JPG uses the native decoder in compatible browsers. When they work, they will get their own page.
