3MB: enough room to keep scans sharp
Insurance claims, university submissions and a long tail of older systems cap uploads around 3MB — awkward, because a phone-scanned document routinely comes out at 5–10MB. The silver lining is that 3MB is plenty when it's spent wisely.
Rather than one blunt quality setting, this tool divides your 3MB across the pages, finds the sharpest quality each page can afford, and carries unused budget forward — so text-light pages subsidize photo-heavy ones. You see the exact final size before downloading, and the file never leaves your device.
How it works
- Add your PDF — the 3MB target is preset (adjust it if your portal says otherwise).

Frequently asked questions
How do I reduce a PDF to under 3MB?
Just add it — the target is preset. A 3MB allowance usually means near-original quality even for long scans.
Where does the 3MB limit come from?
Insurance claim uploads, university submission systems and some older email gateways draw the line around 3MB.
Is my document uploaded during compression?
No. Everything runs in your browser — your documents never touch a server.
