Frequently asked questions

Can I edit a PDF online for free?

Yes. The tools here let you merge, split, rotate and convert PDFs for free, right in your browser, with no sign-up and no watermark. For editing text and images inside a PDF, the free Core PDF desktop app does that.

Do I have to upload my PDF to edit it?

No. Every tool on this site runs in your browser, so your PDF stays on your device and is never sent to a server.

How do I edit the actual text in a PDF?

Editing the text and objects inside a PDF page needs a full editor. Core PDF is a free, offline desktop app that edits text, redacts, signs, adds pages and more, without your files ever leaving your machine.

Which PDF edits can I do in the browser here?

You can merge PDFs, split or extract pages, rotate pages, convert PDF to and from Word, and convert between PDF and JPG. Each runs privately in your browser.
