How to Reduce PDF File Size

Large PDF files can be difficult to share. Browser-based tools can help reorganize and optimize PDFs without desktop software.

Common Causes of Large PDFs

High-resolution embedded images, uncompressed scans, and unnecessary metadata all increase file size.

Strategies

  • Split large documents into smaller parts
  • Convert scanned pages to compressed images before creating PDFs
  • Remove unnecessary pages
  • Re-create PDFs from optimized images

For merging and splitting, use our PDF Merger and PDF Splitter tools.
