Making a PDF that's larger than Germany

  A PDF processor written in Go.

  

Slightly tangential: if you are hacking on PDFs, manually or otherwise, this is an incredibly useful tool: https://pdfcpu.io/ (not the author, just a user)

• PdfViewer

  44 502 8.6 Java

  Simple Android PDF viewer based on pdf.js and content providers. The app doesn't require any permissions. The PDF stream is fed into the sandboxed WebView without giving it access to content or files. CSP is used to enforce that the JavaScript and styling properties within the WebView are entirely static.

  

There are some pdf readers that protect you against those things.

On Android, for example, there is the GrapheneOS Pdf Viewer [1]. It's readme has a pretty good explanation of how it works.
