How to resize a photo to 3.5×4.5 cm
- Click Select images and choose a front-facing photo with a plain, light background.
- The size is preset to 413×531 pixels, which is 3.5×4.5 cm at 300 DPI.
- Keep Crop to fill selected so the photo is trimmed to the right shape instead of stretched.
- Click Resize and download. Print at 300 DPI or upload directly.
3.5×4.5 cm in pixels
| Resolution | Pixels (width × height) | Typical use |
|---|---|---|
| 300 DPI | 413 × 531 | Printing, most online forms |
| 200 DPI | 276 × 354 | Online forms with small KB limits |
| 150 DPI | 207 × 266 | Very small uploads (under 20 KB) |
If your form specifies pixels, type them into the width and height boxes instead.
Passport photo checklist
- Background: plain white or off-white, no shadows.
- Face: looking straight at the camera, eyes open, neutral expression, head covering only for religious reasons.
- Framing: the face (chin to top of hair) should fill roughly 70–80% of the photo height.
- Glasses: many countries now ask you to remove them.
Rules differ by country and by form, so check the official requirements before you submit.
Why DPI matters for a 3.5×4.5 cm photo
Centimetres describe a printed size, while a digital file only has pixels. DPI (dots per inch) connects the two: one inch is 2.54 cm, so at 300 DPI a 3.5 cm width needs 3.5 ÷ 2.54 × 300 ≈ 413 pixels. Photo labs and passport offices print at 300 DPI, which is why 413×531 pixels is the safe default. Online forms do not print anything, so they often accept a lower resolution; choosing 200 or 150 DPI simply gives a smaller file that is easier to fit under a KB limit.
Printing several passport photos
Most photo shops print on 10×15 cm (4×6 in) paper, which fits six to eight 3.5×4.5 cm photos. Place copies of the resized image side by side in any photo editor or document at 300 DPI and print at 100% scale, not "fit to page", so each photo keeps its exact size. Cut along the edges with a ruler for a clean result.
Next steps
Exam and job portals often add a file-size limit. After resizing, use Compress to 50 KB or 20 KB, and the Signature Resizer for the signature. Need another size? Use the full Image Resizer.
Private by design
Your photo is resized on your own device. Nothing is uploaded, stored or shared.
Frequently asked questions
How many pixels is 3.5×4.5 cm?
At 300 DPI, the usual print resolution, 3.5×4.5 cm is 413×531 pixels. At 200 DPI it is about 276×354 pixels, and at 150 DPI about 207×266 pixels.

Yes. It is the standard passport photo size used by India, Nepal, the UK, the EU, Australia and many other countries. The US uses 2×2 inches instead.
Will my photo be stretched?
No. Keep Crop to fill selected and the photo is cropped from the centre to the 7:9 shape before resizing, so faces are never distorted.
My form also has a KB limit. What next?
Resize here first, then compress the result to the required size, for example with Compress to 50 KB or Compress to 20 KB.
