Compression Levels

🤖 Smart (AI-Powered) - Recommended

AI analyzes your PDF and automatically selects optimal compression settings based on content type, image quality, and file structure.

Low Compression

Best for documents with important images or graphics. Minimal size reduction (10-20%), maximum quality (95%).

Medium Compression

Balanced option for most documents. Good quality (85%) with reasonable size reduction (30-50%).

High Compression

Suitable for text-heavy documents. Significant size reduction (50-70%) with acceptable quality (75%).

Extreme Compression

Maximum size reduction (70-90%). May noticeably affect image quality (60%). Use only when file size is critical.

100% Secure & Private

All compression happens in your browser. Your files never leave your device, ensuring complete privacy and security.

About Compress PDF

Compress PDF shrinks file size so email and government portals accept your upload. It balances image quality against size—perfect after scanning or merging. Start with a moderate setting; go stronger only if the portal still rejects the file.

When to use it

  • Email a scan that is tens of megabytes
  • Meet a 2MB–10MB portal limit
  • Archive older PDFs without huge storage use

Tips for better results

  • Preview text sharpness after strong compression
  • Compress once—repeated passes rarely help much
  • For text-only PDFs, compression gains may be small

Limitations

  • Already-optimized PDFs shrink less
  • Extreme compression can soften small text in scans

Privacy

Compression is processed for your session only; we do not retain compressed or original copies.

Frequently asked questions
