Supported Formats & Limitations
- Input: PDF files.
- Output: Compressed PDF.

Privacy: What Happens to Your Files
Server-Side Processing: Your PDF is securely uploaded to our server for compression via advanced processing tools. The file is encrypted during transit and automatically deleted from our servers immediately after the download.
Common Problems & Fixes
- File Size Didn't Change: If the PDF is already highly optimized or contains mostly text, further compression is difficult.
- Blurry Images: High compression levels aggressively reduce image resolution. Try Medium or Low compression.
