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.

Shrink PDF online when attachments bounce or portals reject large files. Compress image-heavy scans and brochures on your device, then download a smaller file for sharing.

Shrinking works best on image-heavy scans; born-digital text PDFs may show little gain.

Try balanced compression first—aggressive settings can blur small text on scanned pages.

How to use this tool

Upload your PDF, choose a compression level, preview if available, then download the shrunk file.

Worked example

Example: shrink a 12 MB scanned contract to under 5 MB for an email attachment without losing readable text.

When to use this

  • Email attachments over provider size limits.
  • Upload portals with strict file-size caps.
  • Sharing brochures or photo-heavy reports.

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.
