Compress PDF to Under 100 KB
Job portals and scholarship forms frequently cap attachments at 100 KB, which is brutal for a phone-camera scan. This page opens the scanner with the Under 100 KB preset selected. Drop your photos or an existing PDF, straighten the page with the perspective crop if the shot is tilted, then apply Auto Magic Clean so the background becomes pure white — white areas compress dramatically better than grey ones, which is how the text stays readable at such a small size. The exporter steps quality down first and resolution only afterwards, so words remain legible instead of dissolving. Every step runs inside your own browser using the Canvas API and Web Workers — no upload, no server, no account.

Frequently asked questions
Yes. Auto Magic Clean flattens the background to pure white and sharpens the ink, so the compressor spends its budget on the text rather than on paper noise.
