Frequently asked questions
- Which compression level should I choose?
- Ebook (150 dpi) is the best choice for most documents — significantly smaller size while remaining readable. Choose Screen for maximum compression, or Printer when you need high-quality output for printing.
- Why is my PDF not getting smaller?
- PDFs that are already compressed or contain mostly text may see modest reductions. Scanned documents and image-heavy PDFs compress the most.
- What technology powers the compression?
- We use Ghostscript, an open-source and industry-standard PDF processing engine trusted by professionals worldwide.
