About 35mm * 45mm Converter
What is a 35mm x 45mm Photo Converter & How Does It Work?
The ToolSpark 35mm x 45mm Photo Converter crops, resizes, and formats photographs to the exact $35 imes 45\text{ mm}$ ($3.5 imes 4.5\text{ cm}$) physical dimensions required for international biometric passports and visas. This size is the mandatory legal standard across the United Kingdom (HM Passport Office), European Union Schengen Visas, Canada, Australia, New Zealand, India, Pakistan, Singapore, and Schengen member states.
Biometric Standards & The ICAO 9303 Specification
International passport photographs are governed by the International Civil Aviation Organization (ICAO) Doc 9303 standard:
- Physical Dimensions: $35\text{ mm}$ width by $45\text{ mm}$ height.
- Resolution at 300 DPI:
$$\text{Width} = \frac{35}{25.4} \times 300 \approx 413\text{ pixels}$$
$$\text{Height} = \frac{45}{25.4} \times 300 \approx 531\text{ pixels}$$
(Commonly rendered as $413 \times 531\text{ pixels}$ or rounded to $415 \times 530\text{ pixels}$).
- Head Height Rule (70% - 80% Rule): The distance from the chin to the top of the crown of the head must measure between $32\text{ mm}$ and $36\text{ mm}$ (approximately 70% to 80% of the vertical image height).
- Top Margin: A minimum of $3\text{ mm}$ to $5\text{ mm}$ of clear space must exist between the top of the hair and the upper border of the photo.

Official Embassy Photo Rules
- Lighting: Even lighting across both sides of the face with no flash glare, redeye, or dark shadows behind ears.

- Plain Light Grey or Cream Background: Most European and UK passports require light grey or cream backgrounds rather than bright pure white.
