PDF processing and analysis with open-source tools

• pdfsizeopt

  6 700 0.0 Python

  PDF file size optimizer

This is missing the "pdfsizeopt" suite, that bundles statically compiled utilities to reduce size.

Static compilation means that it will run on most Linux platforms without extra required software.

I believe one aspect of it will remove characters from included fonts that are not used.

It really is quite impressive.

PDFBox can do this. It’s not part of the CLI but it wouldn’t be too hard to add:
