Compression rasterizes pages (text becomes an image) — perfect for portals with size limits, not for editing later.

Frequently asked questions
Do I need Preview or Acrobat on my Mac?
No — this runs in your browser (Safari, Chrome, or any modern browser on macOS), no other app required.
Is this different from Mac's built-in PDF compression?
Preview's "Reduce File Size" export gives you no control over the target — this tool lets you pick a KB target and binary-searches quality to hit it.
Does this upload my file from my Mac?
No. Everything runs locally in your browser — nothing is sent anywhere.
