Compress PDF is an online PDF application on MiOffice AI that reduce your PDF file size while maintaining readable quality. Files never leave your browser — private and secure.

Reduce your PDF file size while maintaining readable quality. Choose from four compression levels — smart compression targets embedded images for maximum size reduction.
Image-heavy PDFs typically shrink 50-90%. Text-only PDFs see smaller reductions since text is already compact. The "maximum" setting is most aggressive.
Text stays razor-sharp — only embedded images get re-encoded. The "medium" setting is a good balance. Use "low" compression if image clarity is critical.
No. Compression runs entirely in your browser via WebAssembly. Your file never leaves your device — unlike iLovePDF or Smallpdf which upload to their servers.
Up to 100MB per PDF. No daily limits, no signup, no watermarks.
Yes. Text, hyperlinks, and searchability are fully preserved. Only embedded images are re-encoded.
Use "high" or "maximum" to get under most email size limits (25MB for Gmail, 20MB for Outlook). Check the output size before sending.
Yes, and these benefit the most since they're essentially large images. Expect 60-90% size reduction on scanned documents.
Similar quality results, but MiOffice is free, needs no account, and processes locally. Adobe requires a paid subscription.
Yes. Works in any modern browser — Chrome, Safari, Firefox on iOS and Android. No app needed.
The compressor handles one PDF at a time for optimal results. Process as many as you need — no daily caps.
Reduce your PDF file size dramatically while maintaining readability. Perfect for email attachments, uploads, and storage.
