Free PDF Compressor — Reduce PDF Size Online

Compress PDF files online in seconds. Our free PDF compressor shrinks file size without watermarks and keeps your documents readable. Choose from three presets: Smallest size (maximum compression), Good quality (balanced), and High quality (larger size, best visuals).

Why compress a PDF?

• Faster sharing by email and chat
• Quicker downloads on mobile networks
• Lower storage and bandwidth usage

How it works

1. Drag & drop your PDF or click to select
2. Pick a compression level: Smallest, Good, or High
3. Click Upload & Compress and download your optimized PDF

Tip: If your PDF is mostly text/vector, “Good” or “High quality” often looks better while still reducing size.
