What is checked
Format is read from the file’s content, not its name, so a PNG renamed to .jpg is caught. Size is checked against the minimum using 1024 bytes per KB and the maximum using 1000, so it passes either way a portal counts. Pixels must match the exam’s size (within 2 px). DPI is shown with the printed size in cm; most portals don’t check it, but some ask for a size in cm.
