Compress PDF — frequently asked questions
How much smaller will my PDF get?
It depends on the file — scanned and image-heavy PDFs shrink the most (often 40-70%), while a PDF that's mostly text is already small and changes less.
Will compression blur my text?
No. Text is kept sharp and selectable; compression mainly optimises the images inside the PDF, so it stays easy to read.
Why do portals reject my PDF for being too big?
Many government and job portals cap uploads at 1-2 MB. Compress PDF brings your file under that cap so it uploads successfully.
Is there a file size limit?
You can compress files up to 25 MB here, which covers almost every form and scanned document.
