HM Passport Office Verified Specifications: Printed 35 × 45 mm & Digital 600 × 750 px
Separate printed photo standards from online digital passport photo rules
Printed photo requirements: For postal paper applications, HM Passport Office mandates physical photos measuring 35 mm wide by 45 mm high, with the distance from the crown of your head to the bottom of your chin measuring precisely between 29 mm and 34 mm (70% to 80% of total print height).
Digital photo requirements (Online Applications via gov.uk): When applying or renewing a British passport online, the digital photo upload must be at least 600 pixels wide by 750 pixels tall, between 50 KB and 10 MB in file size, and taken against a plain light-grey or cream backdrop with head, shoulders, and upper body clearly visible.
GOV.UK No Self-Cropping Instruction: For digital applications on gov.uk, official guidance specifically advises applicants who take their own digital photo not to crop it themselves. The GOV.UK application service automatically crops the portrait during submission. Modifyle helps you verify framing, lighting, and resolution (at least 600 × 750 px, 50 KB–10 MB) beforehand, but we advise uploading the full uncropped portrait to GOV.UK.
Important distinction: The printed 29–34 mm head-height measurement applies specifically to physical paper submissions and must not be described as a digital upload requirement. Modifyle provides guides for both workflows while processing 100% locally in your browser, but cannot guarantee government acceptance.
What Can You Use This Tool For?
Real-world problems solved and intended workflows for this tool.
Digital Photo Requirements for Online Passport Applications (gov.uk)
For digital photos submitted through the gov.uk online passport application portal, HM Passport Office requires images at least 600 pixels wide by 750 pixels tall, file size between 50 KB and 10 MB, showing head, shoulders, and upper body on a plain light-grey or cream background. Note: GOV.UK explicitly advises applicants taking a digital photo on their own device NOT to crop it themselves, as the online system performs automatic cropping. The printed 29–34 mm head-height measurement applies to physical paper photos only.
Printed Photo Requirements for Paper Applications (35 × 45 mm)
Printed photo requirements for paper applications submitted by post mandate physical dimensions of 35 mm wide by 45 mm high, with head height from crown to chin between 29 mm and 34 mm (70%–80% of photo height).
Plain Light-Grey or Cream Backdrop Framing
HM Passport Office specifically rejects pure stark white backdrops, dark backgrounds, or patterned walls with shadows behind the head.
UK Visas & Immigration (UKVI) Application Photos
Prepare standard 35×45 mm biometric photos for biometric residence permits (BRP), graduate visas, and skilled worker visas.
How It Works in 3 Simple Steps
Upload Portrait for Verification
Choose a sharp headshot taken against a plain light-grey or cream backdrop.
Select Workflow (Print vs Digital)
For paper prints, align head between 29 mm and 34 mm. For online digital renewal, verify that head, shoulders, and resolution (≥ 600×750 px) meet GOV.UK standards.
Submit According to Workflow
For paper printing, export the 35×45 mm crop. For online digital renewal, upload the uncropped photo directly to GOV.UK to allow their system to crop it.
- GOV.UK officially instructs applicants taking a digital photo on their own device NOT to crop the photo themselves — the online application tool crops it automatically during upload.
- The 29–34 mm head-height measurement is a printed-photo requirement for paper submissions; do not describe it as a digital upload requirement. Digital uploads require at least 600×750 px (50 KB–10 MB) with head and shoulders visible.
- HM Passport Office strongly advises removing eyeglasses (even clear prescription glasses) to eliminate glare and automated validation failure risk. Background must be plain light-grey or cream, not pure white.
- Modifyle assists with sizing and framing previews but cannot guarantee government acceptance. HM Passport Office has final authority on photo compliance.
