Minimizing the size of JavaScript code (like JS Minifier) or PNGs (like Tiny PNG) are meant to reduce the bandwidth and speedup loading times of websites.

I'm looking for a similar thing but for PDF files. For testing purposes (in unit tests if that matters) I need PDFs which are small.

  • the operation should be lossless by default
  • minimizing may remove embedded fonts and assume they are present on the system
  • minimizing may change the PDF version
  • it should provide an option to resize images (no longer lossless)

The tool needs to work on Windows and cost less than 10 EUR or 10 USD.

Free PDF Compressor could be a solution.


You could use online PDF compressors such as I love PDFs which worked for me.

It reduced one of my PDFs from 557 MB to 89 MB.


GhostScript could work, it has a bunch of different options. It's a powerful but perhaps not too easy to use tool. There are however many examples of usage around the web, e.g.: https://stackoverflow.com/questions/10450120/optimize-pdf-files-with-ghostscript-or-other https://askubuntu.com/questions/113544/how-can-i-reduce-the-file-size-of-a-scanned-pdf-file
