When You Need a PDF Under 1MB

Some systems are stricter still — older government portals, certain exam boards and message attachments often cap at 1 MB. That's an aggressive target for anything scanned, so this page sets a 1 MB goal and pushes the compression harder to meet it.

A Realistic Expectation at 1MB

Reaching 1 MB means a real drop in image fidelity, which is fine for a readable scan but visible on photo-heavy pages. Everything runs in your browser, and you'll be told whether the 1 MB target was met or how close it got.
