This tool re-renders each PDF page as an optimized image, with quality and resolution controls. It is the most effective approach for scanned or photo-heavy PDFs — exactly the ones that balloon in size. Note: text is no longer selectable in the output file.

Frequently asked questions

How much smaller does the file get?

Scanned PDFs typically shrink 60–90% at the default setting. Text-only PDFs may shrink little — in that case the original is probably already small.

Why is text no longer selectable?

To reach maximum in-browser compression, each page is converted to an image. If you need searchable text, only compress scanned PDFs (which are already images).

Which setting should I use for e-mail?

The "E-mail" profile (quality 60, 110 dpi) gets most documents under 10 MB while staying readable on screen.
