What is a PDF compressor?

A PDF compressor reduces file size so documents fit email limits and upload portals. Choose a compression level and download a smaller PDF after secure processing.

Compress PDF to 500KB when a portal, job application, or government form enforces a strict size cap. Use stronger compression and verify readability after download.

500 KB caps often appear on government and university portals—compress early in your workflow.

Multi-page documents may need splitting before aggressive compression to stay readable.

How to use this tool

Upload your PDF, apply strong compression, check file size after download, and re-run with adjusted settings if needed.

Worked example

Example: compress a one-page scanned ID from 1.2 MB to under 500 KB for a visa application portal.

When to use this

  • Government or university forms with strict caps.
  • Job portals limiting resume scan size.
  • Mobile upload flows with low size thresholds.

Common examples

  • 12 MB scanned contract → Balanced compression often targets email-friendly sizes; text-only PDFs may barely shrink.
  • Image-heavy brochure at 25 MB → Strong compression for upload portals; review text readability after download.
  • Born-digital 2-page invoice at 400 KB → compression may show little gain; organize or split instead if still too large.
  • 15 MB marketing PDF → Balanced mode for email; verify logos after download.
  • Scanned 80-page packet at 45 MB → Strong mode for portal upload limits.
