Resize Image to 3.5×4.5 cm (413×531 px)
Convert ruler measurements into pixels: 35 mm × 45 mm photo box at 300 DPI maps to roughly 413×531. Built for biometric passport layouts — always verify head-size rules with official overlays.

What this tool solves
Applicants think in centimetres; portals ask for pixels. This URL bridges that gap without mixing unrelated social presets. It complements — not replaces — exam-specific guides like NEET when you need neutral passport wording.
Specification table
| Item | Detail |
|---|---|
| Physical format | 35 mm wide × 45 mm tall |
| Typical DPI assumption | 300 DPI |

How to use
- Shoot or select a high-resolution frontal portrait.
- Use Cover if you must fill the frame; Contain if head already framed loosely.
- Resize, inspect eyes/chin positioning, download.
- If the portal caps file size, chain target-size compressors.
Best practices
- Plain light background behind subject.
- Neutral expression unless guidance allows a smile.
- No heavy filters — skin texture must look natural.
Common mistakes
- Tilting the camera — keep horizon level.
- Casting coloured lights on the face — causes rejection even if pixels are correct.
Privacy
Biometric photos stay offline during editing.
Frequently Asked Questions
Is 3.5×4.5 cm the same everywhere?
Many countries use the 35×45 mm biometric standard for passport booklets, but digital upload limits (KB) and background colour rules still vary. Always read your issuer’s PDF guidance.
Why 413×531 pixels?
At 300 pixels per inch, 3.5 cm ≈ 413 px width and 4.5 cm ≈ 531 px height. That is the math behind most “ICAO photo” generators.
How is this different from the NEET-specific page?
NEET adds exam-year instructions and combined signature workflow. This page targets generic searches for **3.5×4.5 cm** without tying copy exclusively to NTA.
Are uploads stored?
No — everything stays local.
Does this enforce head-size ratios?
No automated tool replaces official overlay templates. Use government PDF overlays when provided.
JPEG only?
Downloads follow the resize pipeline JPEG settings — fine for most portals; confirm allowed formats.
