💡 Compression Tips

  • Low: Best for PDFs with important images that need to stay sharp
  • Medium: Balanced option for most documents (recommended)
  • High: Good for text-heavy PDFs or when file size is critical
  • Maximum: Most aggressive compression, may affect image quality

Did you know? Most PDF file size comes from embedded images. Our compressor intelligently recompresses images while preserving text quality. PDFs with scanned images can often be reduced by 70-90% without visible quality loss!
