About Compress PDF
Government and bank portals often cap uploads at 100 KB to 2 MB, while a phone scan of the same document can run to 10 MB or more.
Lowering the DPI has a bigger effect than lowering quality. Start at 150 DPI and 80% — if it still will not fit, step down to 72 DPI before sacrificing more quality.
Frequently asked questions
Will the text get blurry?
No. Unlike converters that turn pages into pictures, text and line art are kept as vectors at every level; only embedded photos are resampled.
Which level should I pick?
Recommended (150 dpi) suits email and web. Print quality keeps 300 dpi images. Maximum is for strict upload limits. Lossless changes nothing visible.
The file did not get smaller — why?
It was already optimised. The tool never returns a larger file than you gave it.
