Usage Guide

ID photos get rejected for the same handful of reasons: wrong size, too dark, busy background, awkward file size. This tool checks size, ratio, brightness, background uniformity and file size locally against your chosen spec — no upload. Screen before you submit.

1. One-click screening

  1. Upload a frontal portrait (plain background works better).
  2. Pick the target PHOTO_SIZES spec and choose ≥ floor vs exact pixels.
  3. Press Run check and fix per the hints: undersized → resizer; dark → more light; busy bg → background tool; oversized → JPG quality or image compressor.

2. What each of the five checks covers

Size — against the selected PHOTO_SIZES entry (≥ or exact). Aspect ratio — relative to that target, not a hard-coded 3:4. Average brightness — roughly 100–210. Background uniformity — top 10% sample; solid backdrops usually stay under ~25 std. File size — advisory ~10–200KB band (portals vary). Passing all five is not acceptance: head proportion, expression and dress code stay manual — the issuing authority has the final word.

3. It is a pre-screen, not an official verdict

  • Catches: wrong size, severe under/over-exposure, cluttered backgrounds, awkward file sizes — high-frequency rejection causes.
  • Cannot judge: head-to-frame proportion, visible ears, expression, dress code — check those against the specific document rules.
  • Use it to filter out clearly doomed candidates in seconds instead of eyeballing each one.

FAQ

Five items: size (against your chosen spec, either “≥ target pixels” or “exact match”), aspect ratio, average brightness (roughly 100–210), background uniformity (sampled along the top band), and file size (an advisory ~10–200KB band).

No. It is a practical pre-screen built from common requirements — it catches wrong sizes, underexposure, busy backgrounds, and abnormal file sizes — but formal documents follow the issuing authority's rules.

Triage by the hint: re-crop with the resizer when size or ratio is off, swap the background or reshoot when it is too busy, reshoot for darkness, and drop JPG quality one notch on export when the file size is out of band — then re-run the check.

Gray zones exist: brightness sitting right at the threshold, mild background gradients, or a file size just on the line. Treat those results as advisory — retest with another sample or defer to the accepting authority.

No — all five metrics are computed on the spot inside the browser.
