Resize Your UK Passport Photo to 35x45 mm at 600 DPI
Applying for a UK passport or visa requires a photo that meets strict government specifications. HM Passport Office uses automated facial recognition to validate photos, and incorrect sizing is the most common reason for photo rejection.
This free UK passport photo resizer tool helps you resize your photo to exactly 35x45 mm at 600 DPI with no server uploads.

Why UK Passport Photos Get Rejected
HM Passport Office rejects nearly 1 in 10 passport photos due to incorrect specifications. The automated facial recognition system measures head height, eye position, and background uniformity. Photos with the wrong dimensions, low resolution, or shadows are rejected outright, causing delays of up to 10 weeks in passport processing.
Common Mistakes to Avoid
- Wrong dimensions: 35x45 mm is the standard — even 1mm off can trigger rejection
- Low resolution: UK Gov requires 600 DPI for digital uploads — lower DPI photos fail
- Incorrect background: Light grey or cream is required, not pure white
- Glasses on: All glasses must be removed, even if worn daily
- Shadows on face: Even lighting is critical — no shadows behind the head or on the face
