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.

Reduce PDF file size when attachments bounce or upload forms reject your document. This tool lowers image resolution and removes redundant data while keeping text readable—pick the compression level that fits your use case.

File size usually comes from embedded images. Reducing image DPI inside the PDF delivers the biggest wins on scans and photo exports.

Always keep an uncompressed original if you may need to edit or print at high quality later.

How to use this tool

Upload the PDF, select compression strength, and download. Check readability before sending important documents.

Worked example

Example: a camera-scan PDF at 18 MB drops to about 4 MB on Balanced compression—small enough for most email providers.

When to use this

  • Fixing 'attachment too large' email errors.
  • Meeting LMS or application upload limits.
  • Speeding up sharing on slow connections.

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.

FAQ

Frequently asked questions

What compression level should I use?

Balanced is a good default. Use Basic for minimal quality change; Strong when size matters more than image fidelity.

Does reducing size remove pages?

No pages are removed—compression targets images and redundant objects within the file.

Is there a maximum file size?

Large files may take longer or hit browser memory limits. Split very large PDFs first if needed.
