Applying online: check, don't crop
For an online application, HM Passport Office wants the original photo: in colour, unaltered by software, at least 600 pixels wide and 750 pixels tall, between 50 KB and 10 MB, against a plain light-coloured background that contrasts with you. Include your head, shoulders and upper body. The service crops the photo itself, so cropping it beforehand can make it fail.
Choose Check for online application and select the photo you plan to upload. The tool checks the file size and pixel dimensions, whether your head and shoulders are in view, whether your eyes are open and your mouth is closed, and whether the background looks plain and light. Nothing is changed; upload the same original file.
Paper applications: 35 × 45 mm prints
Printed photos must be 45 mm high and 35 mm wide, with your head 29–34 mm from the bottom of the chin to the crown, meaning the top of the head rather than the top of the hair. Choose Make printed photos: the tool aims for about 31.5 mm and lays out eight photos on a 6 × 4 inch sheet with cut guides.
HM Passport Office asks for professionally printed photos on plain white photo paper, two identical copies, with no border. Take the downloaded sheet to a photo lab rather than printing it on a home inkjet printer, then check the head size on the print with a ruler.
Frequently asked questions
Should I crop my photo for an online application?
No. HM Passport Office wants an unedited photo of your head, shoulders and upper body, at least 600 × 750 pixels and 50 KB to 10 MB, and crops it for you. Check your original here, then upload that file.
When do I need printed 35 × 45 mm photos?
Paper applications need printed photos 45 mm high and 35 mm wide, with your head 29–34 mm from chin to crown. HM Passport Office asks for professional-quality prints on plain white photo paper, so take the sheet to a photo lab.
Is my photo uploaded?
No. Checking and cropping run in your browser. The face and person models download from Google's model host and the runtime from jsDelivr on first use.
