How do I make a passport size photo online?
Upload a front-facing photo to this passport photo resizer and choose a size: 3.5 × 4.5 cm (the common Indian exam and document size), 2 × 2 inch or 51 × 51 mm. Drag the crop box so your face sits in the centre, set a KB limit if your form has one, and download. The tool sets the exact pixels for 300 DPI, so the photo prints at the right size too.
What is "passport size" in cm, mm and pixels?
"Passport size" is not one fixed size worldwide. In India, most exam forms, ID cards and admission forms mean 3.5 cm wide × 4.5 cm tall (35 × 45 mm). Some visa forms use a square 2 × 2 inch photo. On screen, these sizes are measured in pixels, which depend on the DPI (dots per inch):
| Photo size | At 200 DPI | At 300 DPI (print quality) | Common use |
|---|---|---|---|
| 3.5 × 4.5 cm (35 × 45 mm) | 276 × 354 px | 413 × 531 px | Exam forms, ID cards, Indian documents |
| 2 × 2 inch (51 × 51 mm) | 400 × 400 px | 600 × 600 px | Some visa and travel forms |
| 3 × 4 cm | 236 × 315 px | 354 × 472 px | Some school and office ID cards |
| 4 × 6 inch postcard | 800 × 1200 px | 1200 × 1800 px | Postcard-size photo uploads |
For an online upload, the pixel size and KB matter. For printing, 300 DPI gives the sharpest result.
How to get the face position right
Most passport and exam rules ask for a similar look. Use these checks before you download:
- Face covers about 70–80% of the photo height, from chin to the top of the hair.
- Eyes open, looking straight at the camera, with a neutral expression.
- Plain white or light background, with no shadows behind the head.
- Both ears visible where possible, and no caps or dark glasses.
- Even lighting on both sides of the face.
The crop box in the tool always keeps the correct shape, so you only need to move and resize it until your head is centred with a little space above.
Steps to resize a passport photo
- 1Upload a photo
Take it against a wall in daylight, at eye level, from about 1–1.5 metres away.
- 2Pick the passport size
3.5 × 4.5 cm is selected by default. Choose another preset or Custom for different numbers.
- 3Adjust the crop box
Drag to move it and pull the corner to resize. The shape stays locked to the chosen size.
- 4Set a KB limit (optional) and download
Turn on "Limit file size" if your form says, for example, "below 50KB".
Passport photo for an Indian passport application
If you are applying for an Indian passport, check the current photo guidance on the Passport Seva website. Photos are often taken at the Passport Seva Kendra itself. For visa photos, always follow the embassy's official specification. The US Department of State, for example, publishes detailed passport photo rules.
