FAQs
How much smaller will my PDF get?
It depends on the file. Scanned and image-heavy PDFs often shrink dramatically; documents that are mostly text are already small, so gains are modest. If compression wouldn't help, the original is kept.
Will compressing hurt the quality?
Higher-compression settings reduce image detail to save space; choose a gentler level to keep pages crisp. Text stays sharp either way.
