Show HN: CrabPDF – privacy-first PDF editor that edits real text
Most PDF editors just overlay text boxes. CrabPDF modifies the actual text inside the file. Nothing leaves your computer... no server, no account, works offline.

I totally understand the concern.
That’s exactly why I suggest installing it as a PWA and then disabling network access on the PWA. In my opinion, that’s actually the best way to use it.

In-browser PDF editor
Built a client-side PDF editor. No uploads, no server everything runs in the browser.
Unlike typical tools that use overlays or server-side processing, this edits the actual PDF structure using PDF.js + pdf-lib.

I will study the subject, that's the same question I had today. For now I've implement a stupid parser that convert the html to react component.
