Frequently asked questions
How much smaller will my PDF get?
It depends on the file, but the Low setting often cuts size by 70% or more. Medium is a good balance, and High keeps near-original quality.
Will compression hurt quality?
Pages are re-rendered as optimized images, so some fine detail is lost. Choose High quality if sharpness matters most.
Is it free and private?
Yes. No signup, no cost, and your file never leaves your device — compression happens in your browser.
Is there a file size limit?
No hard limit, but very large PDFs with hundreds of pages may take a while and use significant memory.
