21×30 mm photo requirements

A 21×30 mm photo is 21 × 30 mm (248 × 354 pixels at 300 DPI) on a white or off-white background, saved as a JPEG under 300 KB. The head must measure 24 mm (80% of the height) from chin to crown, which is the part most photo tools ignore — a photo can be exactly the right size and still be rejected for a head that fills too much or too little of the frame.

How to make one

  1. Choose a well-lit, front-facing photo of yourself — a phone photo is fine.
  2. The head is measured and framed to the 21×30 mm rule automatically.
  3. The background is replaced with white or off-white by a matting model.
  4. Download one photo for an online application, or a print sheet with cut lines.

Is my photo uploaded anywhere?

No. There is no server to upload it to — the cropping, face detection and background removal all run inside this browser tab, and nothing is stored. Turn off your Wi-Fi once the page has loaded and it still works.
