NilPDF Edit lets you write text directly onto any page of a PDF — fill in a blank, add a comment, sign off with a note — all rendered and applied locally in your browser. Click where you want the text, type it, and it’s placed on the page. Download the edited PDF when you’re done. Nothing is ever uploaded to a server.

100% private. Your files are processed entirely inside your browser using WebAssembly. Nothing is uploaded to any server. NilPDF has no backend — there is no server to send your files to.

Frequently Asked Questions

Is editing a PDF really free?

Yes — completely free, unlimited use, no account required.

Are my PDF files safe when I edit them?

Your files never leave your device. All processing happens in your browser using WebAssembly (Pyodide). NilPDF has no server — there is nothing to upload to.

Can I edit existing text in the PDF?

Not yet — NilPDF Edit adds new text on top of the page, it doesn't modify existing text in the document. To black out or replace existing content, use the Redact tool instead.
