Compress PDF
Most email providers cap attachments around 25 MB, and plenty of upload portals are stricter than that. Compress shrinks a PDF to fit, with a choice of how much you’re willing to trade quality for size.

Frequently asked questions
Will compression make my text blurry?
Lossless keeps text sharp and selectable. Balanced and Strong re-render pages as images, which trades selectable text for a much smaller file.
How much smaller will my file get?
It depends on the source — scanned, image-heavy PDFs shrink the most; already-optimized text PDFs shrink the least.
Which mode should I use for a scanned document?
Balanced is the best starting point; use Strong if size matters more than clarity.
Does compression change the content, or only the file size?
Balanced and Strong re-render pages, so very fine print can look slightly softer. Lossless never changes how pages render.
