Can I compress a PDF without losing quality?

Yes. ExactPDF uses smart compression that reduces file size by 50-90% while preserving text sharpness and image clarity. Choose from 3 compression levels.

How does PDF compression work?

PDF compression removes redundant data, optimizes fonts, and downsamples images proportionally. ExactPDF applies lossless compression to text and selective lossy compression to images.

What compression level should I use?

Use Light (10-30% reduction) for maximum quality, Medium (30-60%) for a balanced result, or Heavy (60-90%) when file size is the priority.

Why Compress PDFs?

Large PDF files can be problematic for email attachments, web uploads, and storage. Compressing PDFs helps you:

Reduce email bounce-backs - Many email servers limit attachment sizes

Speed up web uploads - Smaller files upload faster

Save storage space - Keep more documents without running out of space

Improve sharing - Faster downloads for recipients

The Secret to Quality Compression

The key to maintaining quality while reducing size is understanding what makes PDFs large:

High-resolution images - Often the biggest culprit

Embedded fonts - Can add significant size

Metadata - Hidden data you may not need

Redundant objects - Duplicate resources
