Frequently Asked Questions
Will compression reduce text quality?
Each page is turned into a compressed image, so text will still be readable at Low/Medium levels but won't be selectable or searchable afterward.
What's the difference between compression levels?
Low keeps pages near original resolution and quality with modest size reduction. High reduces both resolution and image quality for maximum size reduction, with more visible quality loss.
Is my PDF stored on your servers?
No. Everything happens locally in your browser — your file is never uploaded anywhere.
Why didn't my file get smaller?
PDFs with mostly text and few images have little room for compression, and rasterizing them can sometimes increase size — try "Low" or keep the original.
