When you need to register for an exam, apply for a document, or send a resume, you suddenly realize you don't have a ready ID photo and no time to visit a photo studio. What's worse, there are so many sizes — 1-inch, 2-inch, small 1-inch — and when you upload a regular photo it always gets flagged with "does not meet size requirements."
The good news is you can crop a normal photo into a standard ID photo yourself at home. Here are the common ID photo dimensions, plus how to crop them with an online tool.
Standard ID Photo Sizes at a Glance
Different uses and scenarios call for different ID photo sizes. Here are the most common:
| Type | Size (mm) | Pixel equivalent (300dpi) | Common uses |
|---|---|---|---|
| 1-inch | 25×35mm | 295×413px | Resume, registration |
| Small 1-inch | 22×32mm | 260×378px | Driver's license |
| Large 1-inch | 33×48mm | 390×567px | Passport, Hong Kong/Macau permit |
| 2-inch | 35×49mm | 413×579px | Diploma, onboarding |
| Small 2-inch | 35×45mm | 413×531px | Civil service exam |
Note: different organizations may have slightly different pixel and resolution requirements, so always follow the specific rules of the agency you're applying to.
Ways to Make an ID Photo from a Regular Photo
| Comparison | Online crop tool | Photo studio | Mobile editing app |
|---|---|---|---|
| Cost | Low | Higher | Low |
| Time | Minutes | Need to go out and wait | Minutes |
| Precise sizing | ✅ By spec | ✅ | ⚠️ Manual |
| Background handling | ✅ | ✅ | ✅ |
| Privacy | ✅ Local processing | — | ⚠️ Some upload to cloud |
ID photos need "precise sizing + proper background," so cropping by standard specs with an online tool is more reliable than manually adjusting in a mobile app.
ID Photo Cropping Notes
- Keep the background simple — white or blue backgrounds are the most universal; cluttered backgrounds tend to fail
- Front-facing, no hat — face the camera, ears visible, no headwear, to meet the basic rules
- Natural expression — look level at the camera with a natural expression
- Crop to spec — crop to the standard size first, then compress the file as needed
- Plenty of pixels — crop from a high-res original to avoid blur when printing or enlarging
How to Crop an ID Photo with PixelForge
Open the PixelForge multi-size crop tool. Everything runs locally in your browser, so your ID photo is never uploaded to a server — your privacy is protected.
Step 1: Upload a regular photo. Pick a clear, front-facing photo with a simple background.
Step 2: Choose the ID photo size.
- The tool has common sizes like 1-inch and 2-inch built in — just select one
- Or enter custom width and height pixels to match your specific organization's requirements
Step 3: Adjust the crop box and export. Place your face in the right spot within the crop box, confirm the size and position, then download. If the file is too large, run it through a compression tool to bring it within the platform's limits.
Summary
The key to cropping an ID photo is "crop to a standard size + keep the background simple + start from a high-res original." With an online crop tool that has common sizes built in, you can make a spec-compliant ID photo at home in minutes.
