Read the form first
Note the two numbers the form gives you: the dimensions (for example 200 x 230 pixels) and the size cap (for example 50 KB). You need to satisfy both.
The order that works
- Crop to the required framing — usually head and shoulders for a photo, or a tight box for a signature.
- Resize to the exact pixel dimensions.
- Compress until you are under the KB cap. If you cannot get there, reduce the dimensions slightly and repeat.
Signatures
Scan or photograph on white paper in good light, crop tightly, convert to a small JPG, and compress. Signature caps are often 10–20 KB.
Common reasons a form rejects your photo
- Wrong format: the form wants JPG/JPEG but the file is PNG or HEIC (iPhone).
- Dimensions off by a few pixels: many portals check the exact width and height, not just the KB size.
- Background: most forms want a plain white or light background with no shadows.
- Framing: the face should be centred and fill most of the height, with the top of the head and shoulders visible.
The Passport Photo Maker handles framing, background and exact sizing in one go - then check the final file against the form's numbers before you submit.
