What Is PDF Compression?

PDF compression is the process of reducing the file size of a PDF document while maintaining acceptable readability and layout quality. This is useful for sharing files via email, messaging apps, or online platforms.

Why Can a PDF Become Larger After Compression?

  • The PDF contains mostly text that is already optimized
  • Images are re-rendered at higher resolution
  • The original file was already compressed

This compression tool works best with scanned documents or PDFs that contain large images.
