Reduce PDF File Size

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.

Secure Server-Side

Your file is uploaded securely for temporary processing. See the tool details below for retention behavior.

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.

How it works

Upload a PDF and choose Basic, Balanced, or Strong compression. The browser uploads your file directly to private temporary storage using a short-lived link. A secure Ghostscript container compresses the PDF, then you receive a temporary download link. Original and compressed files are automatically deleted within one hour.

Limitations

Files upload to a secure server for compression and are auto-deleted within one hour. Scanned PDFs may not shrink much without OCR.

Privacy and file handling

Your file is uploaded securely for temporary processing. See the tool details below for retention behavior.

Important notice

Compression runs on a secure server with Ghostscript. Your file is uploaded privately and automatically deleted within one hour. Already-optimized PDFs may not shrink much. Maximum 50 MB and 200 pages.

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.
