FAQ

Is the photo uploaded anywhere?

No, everything happens in your browser.

What size should I use?

Whatever the form states. If it says centimetres, multiply by 10 and use millimetres (3.5×4.5 cm = 35×45 mm).

What does “Crop to fill” cut?

The extra at the edges, keeping the centre. If your head gets cut, choose “Fit whole photo” or crop the photo first.

Does this make it a valid passport photo?

No. This only adjusts the file; each document’s rules about background, lighting and framing still apply.
