Passport and ID Photo Size in Pixels: 35×45 mm, 2×2 in and 3×4 cm Explained
On this page
Short answer: a passport photo of 35 × 45 mm is 413 × 531 pixels at 300 DPI, and a 2 × 2 inch photo is 600 × 600 pixels. Imgovo’s DPI & Size Calculator has presets for both, Crop Image can cut your photo to the exact pixel size, and the Image Compressor can bring the file under an upload limit. Everything runs in your browser, so your face is never uploaded. Imgovo does not check whether the photo meets the rules of an authority; that is your responsibility.
Why the size differs from country to country
A passport photo is defined in millimetres or inches by the issuing authority. To turn that into pixels you need a resolution: pixels = inches × DPI, and 1 inch = 25.4 mm. At 300 DPI, 35 mm is 413 pixels and 45 mm is 531 pixels.
Common sizes in pixels
| Photo | Size | 300 DPI | 600 DPI |
|---|---|---|---|
| Germany, France, Italy and many other EU countries; UK | 35 × 45 mm | 413 × 531 px | 827 × 1063 px |
| United States (passport) | 2 × 2 in (51 × 51 mm) | 600 × 600 px | 1200 × 1200 px |
| Brazil (ID and document photo) | 3 × 4 cm | 354 × 472 px | 709 × 945 px |
These are examples. Other countries, and other documents such as visas, residence permits, driving licences and ID cards, can use different sizes, and rules change. Always check the current requirements of the authority that issues your document.
For any other country or document, use the size published by the issuing authority and enter it in the calculator under Custom.
Step by step
- Find the pixel size. Open the DPI & Size Calculator and pick “Passport photo 35 × 45 mm (EU)” or “US passport photo 2 × 2 in” from the “ID photos & cards” group of print sizes. For another size, choose Custom and type the width and height in mm, cm or inches. The calculator shows the pixels at your DPI (300 is the usual choice for printing).
- Crop to the right proportions. Open Crop Image. For 35 × 45 mm choose a custom ratio of 7:9; for 2 × 2 inches choose Square 1:1. Move and resize the box so the face is centred, as the rules require.
- Set the exact pixels. In the output size, choose “Crop and resize to exact pixels” and enter 413 × 531 (or 600 × 600). If your selection has fewer pixels than the target, the tool asks whether to enlarge it (the result may look soft) or keep the selection’s own pixels. It never decides this silently.
- Save as JPG. Most online forms and print services accept JPG.
- Reduce the file size if the form requires it. Open the Image Compressor, choose “Target file size” and enter the limit, for example 200 KB. See also How to compress an image under 100 KB.
For online applications
Some portals ask for an exact pixel range, a file format and a maximum file size, and they can reject a photo that does not fit. Read the instructions of the portal you are using, because requirements change. Typical things to match are the pixel dimensions, the file format (usually JPG), the file size limit and the proportions of the picture.
For printing at a shop or at home
Print at the exact size (for example 35 × 45 mm) without letting the shop scale or crop the picture. A photo with enough pixels is not enough on its own: a print of 35 × 45 mm needs at least 413 × 531 pixels to reach 300 DPI. If you set the DPI label with “Download with DPI” in the “Change DPI label” tab of the calculator, only the label in the JPG header changes; the pixels stay the same. For more on this, see How many pixels you need to print a photo.
What Imgovo cannot do
- It does not check head position, background colour, shadows, expression, glasses or any other rule of a passport authority.
- It does not change your appearance, and you should not retouch a document photo in a way the authority forbids.
- It does not know the requirements of every country. The table above shows examples only.
Privacy
A passport photo is sensitive personal data. All the steps above run locally in your browser, your photo is never uploaded, and the saved file contains pixel data only, so camera details and GPS location are not carried over.

Frequently asked questions
How many pixels is a 35×45 mm passport photo?
At 300 DPI a 35 × 45 mm photo is 413 × 531 pixels. At 600 DPI it is 827 × 1063 pixels.
How many pixels is a 2×2 inch passport photo?
At 300 DPI a 2 × 2 inch photo is 600 × 600 pixels. At 600 DPI it is 1200 × 1200 pixels.
Does Imgovo check whether my photo is accepted?
No. Imgovo gives you the exact pixel size and crops the picture, but it does not check head size, background, lighting or expression. Those rules come from the authority that issues the document.
My application form asks for a maximum file size. What can I do?
Crop to the required pixel size first, then use the Image Compressor with a target file size (for example 200 KB). If the target cannot be reached, the tool tells you and gives the smallest result it could make.
Can I use a selfie?
That depends on the authority. Many require a neutral expression, even lighting and a plain background, and some do not allow filters or retouching. Check the official rules before you use any photo.
Is my photo uploaded to a server?
No. The DPI & Size Calculator, Crop Image and Image Compressor run in your browser, so your photo never leaves your device.
