Passport Size Photo Online

A passport-size photo has a fixed shape — 35×45 mm, which works out to roughly 413×531 pixels at 300 DPI — and getting those proportions right is what makes the photo acceptable for passports, visas, exam forms and ID cards. This tool has the correct dimensions pre-filled, so you can turn an ordinary photo into a properly sized passport photo in a couple of clicks.

For the cleanest result, crop your picture to a head-and-shoulders shot near the 35:45 ratio first, then drop it here to resize to the exact pixel size. Everything happens in your browser, so the photo you are preparing for an official document is never uploaded to anyone.

What is the correct passport photo size?

The internationally common passport photo is 35×45 mm — 3.5 cm wide by 4.5 cm tall. To use that in a digital tool it needs to be expressed in pixels, and at 300 DPI (the print resolution most authorities expect) that comes to about 413×531 pixels. Those are the values pre-filled in the resizer below, so you do not have to calculate anything.

A few countries and specific forms use slightly different measurements, so always check the exact requirement for your document. Once you know the pixel size a form wants, you can type it straight into the width and height fields and resize to match — the 413×531 default simply covers the most common case.

Crop first for a photo that is not stretched

The one thing that ruins a passport photo is stretching. Because 35×45 mm is a fixed 35:45 proportion, forcing a photo of a different shape into those dimensions squashes or stretches the face. The fix is to crop before you resize.

Use the crop tool to select a head-and-shoulders area that is already close to the 35:45 ratio — head centred, a little space above the hair, shoulders at the bottom. Once the crop matches the target proportions, resizing to 413×531px keeps everything looking natural. This is why the aspect lock here is turned off: you crop to the right shape first, then set the exact pixels.

Tips for an acceptable passport photo

Beyond the size, most authorities share a similar set of expectations for the photo itself. Meeting them before you resize avoids a rejected application:

• Use a plain, light-coloured background with even lighting and no shadows.
• Face the camera straight on with a neutral expression and both eyes open.
• Keep the head centred with a little space above it and the shoulders visible.
• Avoid hats, heavy glare on glasses, and busy backgrounds.
• Confirm the exact pixel size and file limits your specific form requires.
