Passport sizes made simple
Passport photo requirements differ from country to country, and getting the size wrong is the most common reason an online application is rejected. This tool removes the guesswork with ready-made presets for the most-used standards: the 2×2 inch (51×51 mm) square used by the United States and India, and the 35×45 mm portrait used across the UK, the EU/Schengen area and many Asian countries. Tap a preset and the width and height are filled in for you.
Size, shape and file limit together
An accepted passport upload normally has to satisfy three things, and this tool covers all of them:
- Dimensions — set by the preset (or type your own in pixels).
- Aspect ratio — keep "maintain aspect ratio" on so the photo is scaled, not stretched. If your source photo is the wrong shape, crop it to the target ratio first using our crop tool.
- File size — most online portals cap the file between 20KB and 100KB; choose the matching target and the tool compresses to fit.
mm, inches and pixels explained
Forms quote passport sizes in millimetres or inches, but uploads are measured in pixels. The conversion depends on DPI (dots per inch). At the print standard of 300 DPI, one inch is 300 pixels and one millimetre is about 11.8 pixels — so 35×45 mm becomes roughly 413×531 px, and 2×2 in becomes 600×600 px. The presets already use these values, so you can simply pick the one your form names. If a portal specifies an exact pixel size instead, type it directly.
Your photo stays on your device
Passport photos are personal identity documents, so privacy matters. This resizer processes everything locally with the Canvas API — your photo is never uploaded, stored or shared, and it disappears from memory when you close the tab. You can resize as many versions as you need (different portals, different sizes) at no cost and with no watermark.
Frequently asked questions
What is the standard passport photo size?
It varies by country. The two most common are 2×2 inches (51×51 mm, about 600×600 px at 300 DPI) used by the US and India, and 35×45 mm (about 413×531 px) used across the UK, EU/Schengen and India. Pick the matching preset.
Does this tool make my photo meet official biometric rules?
It handles the size and file requirements (dimensions, aspect ratio and KB limit). It does not check biometric rules such as head position, neutral expression or background colour — make sure your original photo already meets those guidelines.
What DPI should a passport photo be?
Printed passport photos are usually 300 DPI. The presets here use 300 DPI pixel sizes (for example 35×45 mm = 413×531 px), which also work for online uploads. For purely online portals, the pixel size is what matters.
Are my photos uploaded to a server?
No. Every step — resizing, cropping and compression — happens locally in your browser using the HTML5 Canvas API. Your image never leaves your device, and nothing is stored or transmitted.
Which output format should I choose?
Choose JPG for photographs and most form uploads because it gives the smallest file size. Use PNG only when you need a transparent background or razor-sharp line art. WebP gives excellent compression but some older government portals do not accept it — check the form requirements first.
