Frequently asked questions

How can I reduce PDF file size without losing quality?
The free Quick mode compresses images and strips waste in your browser for a smaller file that still looks right. Smart and Max modes use stronger, server-side compression for the largest savings.
Is the free PDF compressor private?
Quick compression runs on your device with no upload. Smart and Max upload over a secure connection and the file is deleted right after processing.
Why is my PDF so large?
Usually high-resolution scanned images or embedded fonts. Compression re-encodes images to a sensible resolution, which is where most of the size goes.
