Use this page when you need a UK baby passport photo with a 35 x 45 mm output, plain light background, and a clear face suitable for online renewal or other passport application workflows.

The final file should match the standard UK passport photo size used for babies and infants.
Keep the background light and uncluttered, with no visible objects, patterns, or extra hands in frame.
Aim for a sharp image with even light, visible facial features, and no filters or red-eye effects.
Place the baby against a plain light sheet or blanket with no visible texture.
Avoid hard flash and heavy side shadows so the face stays evenly lit.
Take multiple frames to improve your chance of getting a clean face and stable head position.
Use the maker to clean the background, set the crop, and export the required file.
Blanket folds, visible support items, or dark shadows can make the image non-compliant.
Blur, poor lighting, or partial obstruction can make the facial features hard to assess.
The source photo may be usable, but the final crop can still fail if the framing is off.
