Edit PDF Tools
11 free tools
Editing a PDF usually means one of a few specific things: signing it, stamping it with text, marking up a passage, filling in a form, or trimming the white space off a scanned page. Each of those is a separate tool below.
They all run locally in your browser tab. That matters most for the tools here — signing a contract or filling a form with your details is exactly the kind of document you would not want uploaded to someone else's server.

Edit PDF questions
- Can I edit a PDF without installing anything?
- Yes. Every tool here works in a modern browser. You drop in the file, make your change, and download the result — there is no account, no install and no watermark added to your document.
- Can I add my signature to a PDF?
- Draw your signature on screen with a mouse, trackpad or finger, then place it on the page you want. The signature is drawn into the file rather than pasted as a floating image, so it sits with the page content.
- Why can't I edit the text directly in a PDF?
- A PDF stores characters at fixed positions on a page rather than as an editable paragraph, so there is no cursor to place and no reflow. Editing text means either an overlay — stamping new text over the area — or an AI rewrite, which are separate tools.
- Are my uploaded files stored anywhere?
- No. The file is read, modified and handed back to you from your own browser. Nothing is uploaded, and nothing is kept after you close the tab.
