Frequently asked questions
How much smaller will my file be?
Typically 20–70% smaller. Image-heavy PDFs compress the most. Text-only PDFs with no embedded images may see only modest reduction.
What is the difference between Standard and Strong modes?
Standard reduces image quality while keeping text as vector (sharp at any zoom). Strong converts every page to a rasterised image for maximum size reduction but may slightly soften very small text.
Will compression affect text selection or search?
Standard mode preserves selectable text. Strong mode converts pages to images, so text is no longer selectable in the output - run OCR afterwards if searchability is needed.
