How It Works

Step 1: Upload Your PDF

Drag and drop any PDF file. There are no size limits — compress 1MB or 100MB files.

Pick Light (10-30% smaller), Medium (30-60%), or Heavy (60-90%) compression.

Step 3: Download Compressed PDF

Your smaller PDF downloads instantly. Text stays sharp, images are smartly optimized.

  • 3 compression levels: light (max quality), medium (balanced), heavy (smallest size)
  • No watermarks, no daily limits, no signup — free forever

Common Use Cases

Compress PDF files for email attachments, cloud storage optimization, website uploads, and portal submissions. Essential for sharing large reports, scanned documents, and image-heavy presentations. Works behind corporate firewalls since no files are uploaded — perfect for organizations using Zscaler, Cisco Umbrella, or other proxy-based security.
