Compress scanned PDF
Scans are the heaviest PDFs there are. fits shrinks them to portal-ready sizes — text stays readable, the file stays on your device.
Why scans are huge — and how fits shrinks them
A scanned PDF stores every page as a photograph, usually captured at 300 or 600 DPI. A ten-page contract that would be 200 KB as a normal text PDF easily reaches 20–50 MB as a scan — which is exactly what visa portals, government forms, and email attachments reject. The fix is not to zip the file (PDFs barely zip) but to re-encode the page images at a resolution that still reads cleanly on screen and in print.
fits detects scanned documents and offers modes built specifically for them. For black-and-white paperwork, Sharp & small re-encodes pages as crisp 1-bit images — the same trick fax machines and office copiers use — which keeps letterforms sharp at a fraction of the size. For signed or stamped contracts, Crisp & colour keeps colour exactly where the stamp and signature sit and renders everything else as clean black-and-white text. And the regular size chips work on scans too: pick the portal ceiling and fits downsamples to fit it.
All of this happens in your browser. Scanned paperwork is usually the sensitive kind — contracts, IDs, medical letters — and with fits it never leaves your device: no upload, no server-side copy, and the byte counter at the bottom of the page stays at zero the whole time.
