🗜️ How Does PDF Optimization Work?

PDF optimization reduces file size by restructuring the internal object streams, removing duplicate resources, and eliminating unnecessary data embedded during creation.

This tool works best on:

  • PDFs exported from design tools (InDesign, Illustrator, Canva)
  • Scanned documents with embedded images
  • Files with embedded fonts and metadata
  • Documents that have been edited multiple times

📊 Standard vs Maximum Optimization

Standard Optimization restructures the PDF's internal object streams for more efficient storage. This preserves all metadata, fonts, and document properties.

Maximum Optimization includes all Standard features plus removes embedded metadata like author info, creation dates, and application stamps for the smallest possible file.

Tip: Use Standard for documents you'll share professionally. Use Maximum for personal archiving or when file size is critical.
