About Compress PDF
Reduce the file size of your PDF documents without significant loss in quality. Choose from three compression levels: Low (best quality, moderate reduction), Medium (balanced quality and size), or High (maximum reduction, some quality loss). Ideal for email attachments, web uploads, or saving storage space.
Compression is performed using Ghostscript with different quality presets: screen (high compression), ebook (medium), and prepress (low) to suit your needs.
