使用指南
Most ID photos get rejected for the same handful of reasons: too small, too dark, busy background, wrong head proportion. This tool checks the four key metrics locally — no upload — and tells you in seconds, so you do not waste a trip.
1. One-click checkup
- Upload your ID photo (front-facing, plain background preferred).
- Click Run check for instant results across 4 items (pass / warning / fail).
- Fix as advised: use a larger original if too small, relight if too dark, reshoot or use the background-changer for a busy backdrop.
2. What the four checks cover
Size (at least 295x413 px for 1-inch, below that prints blur); aspect ratio (close to 3:4, the common ID composition); average brightness (100-210 is the safe zone); background uniformity (solid-backdrop requirement). Passing all four is not a guarantee — head proportion, expression and dress code are not judged here; follow the issuing authority.
3. A screening tool, not a ruling
- It catches: too-small files, severe under/over-exposure, obviously busy backgrounds — the top rejection causes.
- It cannot judge: head-to-frame ratio, ear visibility, expression, attire — those need a human check against the specific requirements.
- Use it to filter obvious failures fast instead of reviewing every candidate by hand.
FAQ
Four items: size (meets 1-inch 295x413), aspect ratio (close to 3:4), average brightness (100-210 range), and background uniformity (solid backdrop).
No. It is a practical reference against common requirements — it catches obvious failures (too small, too dark, busy background), but follow the issuing authority's exact rules for formal documents.
