Thirty-five by forty-five millimetres is the passport photo standard across the United Kingdom, the European Union, India, Australia and most of the Commonwealth. This tool produces exactly 413x531 pixels, cropping from the centre so faces stay centred and nothing is stretched.
At 300 DPI that is 413x531 pixels. UK passport rules additionally require the face to occupy 29–34 mm from chin to crown, a plain light-grey or cream background, and no shadows. Indian portals frequently add their own file size cap of 20–50 KB.
The resize happens in your browser and your photo is never uploaded — which matters when the photo is attached to a passport or visa application.
Crop or pad?
Unless your original happens to share the 413:531 aspect ratio, something has to give. There are only two honest options, and the right one depends on what the image is for.
- Crop to fill scales the image until it covers the whole frame and trims the overflow from the edges. This is the default here, and it is what you want for portraits, profile pictures and passport photographs, where the subject is central and the edges are background.
- Fit inside scales the image until it fits entirely, leaving bars at the sides or top. Use it when losing any part of the picture is unacceptable — product photography, diagrams, screenshots, artwork.
What this tool will never do is stretch. A distorted face is instantly obvious and gets official photographs rejected, so squashing to fit is not offered at all.
Why downscaling quality matters
Reducing a 4000-pixel photograph to 413 pixels means throwing away roughly98% of the original pixels, and how you throw them away is visible. A naive one-step resize samples too sparsely and produces aliasing — jagged diagonals, shimmering fine detail, moiré on fabric.
This tool steps down in halves instead, resampling repeatedly until it is close to the target and then making the final adjustment. Each halving averages neighbouring pixels properly, so detail is condensed rather than discarded at random. It is slightly more work and noticeably sharper, particularly on text and textures.

Resizing runs inside this page. For identity photographs in particular this matters: your passport photo is a biometric record, and it should not be sitting in a stranger's temporary folder because you needed to change its dimensions.
Frequently asked questions
How do I resize an image to 35x45 mm (413x531 px)?
Drop your photo above and it is resized immediately. The tool scales the image to fill 413x531 pixels and crops whatever falls outside, so you get exactly those dimensions rather than something merely close. Switch to "fit inside" if you would rather pad the edges than lose any of the picture.
Will resizing to 35x45 mm (413x531 px) make my photo blurry?
Only if the original is smaller than 413x531, in which case pixels are being invented and softness is unavoidable. Coming down from a larger photo is safe: the tool downscales in halving steps rather than one jump, which preserves noticeably more detail than a naive resize.
Does the aspect ratio change?
The output is exactly 413x531. To reach that without distorting anybody's face, the image is scaled until it covers the frame and the overflow is cropped from the edges. Nothing is ever stretched — a squashed passport photo is rejected everywhere.
What file size should the result be?
Most official portals want the finished photo somewhere between 20 KB and 240 KB. Once you have the dimensions right, run it through the compression tool to hit whatever number your form demands.
