Questions
Something missing? Send feedback →Will my text get blurry?
No. Only the pictures inside the PDF are recompressed. Text, fonts and drawings are copied as they are.
Why didn't my PDF get smaller?
Most of a PDF's size is usually its pictures, so a PDF that is mostly text has little to shrink. If the result isn't smaller, the app keeps your original and saves nothing. A PDF already under your size limit is skipped too.
What if it can't reach my size limit?
It saves the smallest version it could make and tells you it couldn't get under the limit.
Can it compress password-protected PDFs?
Not if the PDF needs a password to open. Those aren't supported.
