Frequently asked questions
Are my files uploaded to a server?
No. Every tool runs entirely inside your browser using JavaScript and WebAssembly, so your files never leave your device. Nothing is uploaded, stored, or sent anywhere.
Can I edit the existing text in the PDF?
You can add new text boxes, notes, and highlights on top of the page. Rewriting the original embedded text of a PDF isn't supported in the browser, so the tool overlays your changes instead.
Will my annotations be part of the final file?
Yes. Everything you add is baked into the downloaded PDF and shows up in any PDF viewer.
Is it really free, with no signup?
Yes. Every tool is free to use with no account, no email, no watermarks, and no hidden page limits.
