PDF tools: common questions

In what order should I use the PDF tools?

If you are sending several documents together: first combine them with Merge PDF, then rotate, reorder or delete pages with Rotate and reorder PDF, sign it with Sign PDF and, if it is too big for email, run it through Compress PDF last. If they are photos of paperwork, JPG to PDF turns them into a PDF first.

How can I work with an encrypted PDF?

Use Unlock PDF with the known password to create an unencrypted copy. Protect PDF adds AES-256 encryption. Other tools state whether they accept passwords; none attempts to guess them.

Are my PDFs uploaded to a server?

No. The tool runs inside your browser: documents are read and processed on your device and are not sent to Cocuyo or to any third party. The PDF libraries are served from our own site, with no external services. You can check it in your browser’s network tools: your file is not sent.

Is it really free?

Yes. You can try them before signing up; to download a result or keep using them, 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. They never add a watermark.

What are the limits?

PDFs without a password up to 100 MB per file, processed bit by bit so the tab stays responsive. Some tools have their own limits, such as Merge PDF, which takes up to 20 files and 250 MB in total; each page says so.
