How sizes convert to pixels
Printing and online applications often ask for centimetres, millimetres or inches. At 300 dpi they correspond to:
| Size | Pixels (300 dpi) |
|---|---|
| 2 × 2 inch | 600 × 600 |
| 35 × 45 mm | 413 × 531 |
| 45 × 60 mm | 531 × 709 |
| 50 × 60 mm | 591 × 709 |
| 40 × 60 mm | 472 × 709 |
How to use it
- Choose the size with the buttons above.
- Drop the photo in and convert. The photo is cropped from the centre to fill the exact size.
- Check the result with “Compare”. If the head and shoulders are not framed correctly, crop the photo in another app first, or use “Fit without cropping” to add white padding.
Important notes
- The tool does not detect or centre the face; it only sets the pixel size. Framing, face proportion and background rules vary by authority.
- For a passport, ID, driving licence or visa, always check the issuing authority’s current photo requirements; a correctly sized photo can still be rejected for other reasons.
- There is no background removal here; use a photo taken against a plain background.
- EXIF data (location, camera) is removed from the output.
If there is a file-size limit (for example 200 KB), turn on “Target file size”. You can prepare several people’s photos in one batch. To print them on one sheet, try combining images into one PDF.
