Question 1

How do I set up multi-signature mode in Signature PDF?

Accepted Answer

Enable it by creating a config.ini file, setting PDF_STORAGE_PATH for server storage, and optionally activating encryption with GPG. Detailed steps are in the Configuration section of the README.

Question 2

Can Signature PDF work without an internet connection?

Accepted Answer

Only if self-hosted locally on a server, as it's a web application. It doesn't function as a standalone desktop app, so offline access requires a local server setup.

Question 3

Signature PDF vs Adobe Acrobat for digital signatures?

Accepted Answer

Signature PDF is open-source and self-hostable, offering more privacy but less polished UX and compliance certifications. Adobe Acrobat provides commercial-grade security and ease-of-use at a cost.

Question 4

How to compress PDFs with Signature PDF?

Accepted Answer

Upload your PDF, use the compression feature in the web interface; it leverages Ghostscript to reduce file size while maintaining quality, as noted in the Libraries Used section.

Question 5

Is Signature PDF secure for confidential documents?

Accepted Answer

Yes, especially when self-hosted with encryption enabled for stored files. The open-source code allows security audits, and multi-signature mode includes server-side encryption options.

Question 6

What dependencies are needed for self-hosting?

Accepted Answer

Requires a web server, PHP, and tools like PDFtk, Ghostscript, and poppler-utils, as listed in the Libraries Used. Docker deployment simplifies this but still needs configuration.
