Online form preparation

Get photos, scans and PDFs through upload portals: the right format, the right size, and one file where one is expected.

Upload a file

Before you start

Upload portals check files automatically. They test the format, the pixel dimensions and the file size against fixed rules, and reject anything outside them, usually without saying which rule failed. Read the portal's requirements first, then change only what they ask for.
