Compress PDF

Reduce file size without sacrificing readability.

Compress PDF files online without sacrificing readability

PDF compression reduces file size by optimizing images, embedded fonts, and object streams while preserving a clean reading experience.

Use this when upload limits block sharing, email servers reject large attachments, or storage costs become a concern.

When to use this tool

  • Prepare reports and invoices for email attachment limits.
  • Reduce document payloads before uploading to client portals.
  • Optimize PDFs for faster downloads on mobile networks.

Best-practice tips

  • Start with balanced compression, then move to extreme if needed.
  • Image-heavy PDFs usually shrink much more than text-only files.
  • Preview the output before sending legal or compliance documents.

Quality and limits notes

  • Extreme compression can reduce image quality in scanned documents.
  • Recompressing the same file repeatedly can introduce visible artifacts.
  • Retry with less compression when visual quality matters more.

Privacy and trust

Files are processed automatically and removed after processing windows complete.
