This caused these PDFs to become almost unreadable even on a modern computer.
Here's how you "resize" (actually re-compress) a PDF to PDF with ImageMagick:
Code: Select all
$ convert -density 300x300 -quality 80 -compress jpeg input.pdf output.pdf
- density: This is the target resolution for images (in DPI) for width/height.
- quality: For JPEG it's 1-100, where 100 is best quality (=largest file). For other compression formats see ImageMagic documentation: "-quality".
