What is compress pdf?

Compress means make a file smaller so it is easier to email or upload. You choose how much to shrink. Bigger shrink = smaller file, but photos may look a bit softer. Tip: Image-heavy PDFs shrink the most.

  • Try a stronger compression level if email attachment limits still fail.

Common questions

Start with a medium setting and check the new file size. Increase compression only if email or upload limits still reject the file. Text-heavy PDFs shrink less than photo-heavy scans.
