Compress PDF without losing quality when you need smaller files but must preserve readable text and clear images. Start with balanced compression and review output before sharing.

True lossless compression is rare for scanned pages—balanced presets trade some image detail for smaller size.

Born-digital text PDFs often compress modestly without visible quality loss.

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 your PDF, choose balanced or light compression, preview output, then download if quality is acceptable.

Worked example

Example: compress a 25 MB image-heavy brochure with balanced settings to 8 MB while keeping product photos sharp enough for client review.

When to use this

  • Client-facing documents that must stay sharp.
  • Legal or financial scans with fine print.
  • Marketing PDFs where image clarity matters.

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

Is lossless PDF compression possible?

Text-only PDFs may shrink slightly without visible change. Scanned images always involve some tradeoff.

Which preset preserves quality best?

Start with balanced or light compression. Increase strength only if size is still too large.

Will fonts stay embedded?

Born-digital PDFs keep embedded fonts through standard compression paths.
