Passport Photo Size Tool | 3.5x4.5cm Resize
A passport photo is a standardized portrait required when you apply for or renew a passport. Exact rules vary by country, but the most widely used international size is 35×45mm (3.5×4.5cm) — the format accepted across the UK, the EU/Schengen area, Australia, India, South Korea, and most ICAO-aligned countries — which equals 413×531px at 300dpi. The United States is the main exception, using a 2×2 inch (51×51mm, about 600×600px) square photo. In most standards the face should fill roughly 70–80% of the frame height, sit centered with a small headroom margin, and appear against a plain white or light background. This tool lets you crop an existing photo to the 35×45mm passport spec, preview face position and head size, and download it instantly.

Passport Photo Size Guide (35×45mm & 2×2in)
Passport photo rules differ by country and are often checked for more than size alone — background, face ratio, and how recent the photo is all matter. Always confirm the exact requirements on your country's official passport or visa site before submitting.
| 35×45mm (3.5×4.5cm) is the most common size — used by the UK, the EU/Schengen area, Australia, New Zealand, India, South Korea, and most ICAO-aligned countries. |
| At 300dpi, 35×45mm equals 413×531px. |
| The United States is the main exception, using a 2×2 inch (51×51mm) square photo — about 600×600px at 300dpi. |
| Some portals set their own pixel or file-size limits, so verify your specific country's rules. |
| Keep the face centered rather than pushed to one side. |
| In most standards the head fills roughly 70–80% of the frame height, with balanced headroom and chin spacing. |
| Make sure hair does not cover the eyebrows or facial contour, and that the full face from forehead to chin is clearly visible. |
| Use a plain, light background (usually white or off-white) with even lighting and no strong shadows. |
| Confirm whether a recent photo (often within the last 6 months) is required. |
| Avoid heavily filtered images, glare on glasses, or photos with strong shadows. |
| Preview the saved file in the real upload form to catch awkward cropping or compression. |
Frequently Asked Questions
How many pixels is a passport photo?
It depends on the size. The international 35×45mm (3.5×4.5cm) format is 413×531px at 300dpi, while the US 2×2 inch format is about 600×600px. If a portal specifies other pixel or file-size rules, follow those first.
Can I use a phone photo for a passport photo?
Yes, but a well-lit photo with a clear front-facing pose is much safer. Images that include the upper body and shoulders are usually easier to crop than very close selfies.
Should I save a passport photo as JPG?
Many submission portals commonly accept JPG or JPEG. Some also accept PNG, but if the site does not specify otherwise, JPG is usually the safer default.
Is matching the size enough before submission?
Not always. Many passport photo rules also check the background, face ratio, headroom, and whether the photo is recent. Review the official guide after resizing.
Do the ears need to be fully visible in a passport photo?
Most authorities focus on the full face being clearly visible from forehead to chin with an unobstructed facial outline, rather than on the ears specifically. Accessories that reflect light or hide part of the face can still cause problems, so check your country's latest official photo guide before submitting.
Which countries use the 35×45mm passport photo size?
The 35×45mm (3.5×4.5cm) size is used by most of the world, including the UK, the EU/Schengen countries, Australia, New Zealand, India, and South Korea, and it aligns with the ICAO photo standard. The main exception is the United States, which requires a 2×2 inch (51×51mm) square photo.
