Compress PDF

Reduce PDF file size by compressing images and cleaning up

Large PDF files can be difficult to email, upload, or share. Our PDF compressor reduces file size by optimizing images and removing unnecessary data while keeping your document readable. Choose from three compression levels to balance file size and quality.

Compression Levels

  • Maximum compression: Smallest file size. Best for archiving and emailing. Images may show some quality reduction.
  • Medium (recommended): Good balance. Significant size reduction with minimal visible quality loss.
  • Minimal compression: Lightweight optimization. Preserves near-original quality while slightly reducing size.

When to Compress

  • PDF exceeds email attachment size limits (typically 10-25MB)
  • You need to upload a PDF to a site with file size restrictions
  • You want to save storage space for document archives
  • You need faster upload/download times for large documents
