ID Photo App handles the other ninety percent of ID photos — the badge shot for a new job, the student ID for enrolment, the membership card, the square headshot a portal demands without specifying. Passport tools cover one well-documented format; this site covers everything else, and it’s honest about how much less documented “everything else” is.

The problem it was built around

Search for how big a badge photo should be and you find confident answers that cite no source — because for most non-passport formats there is no binding source. Employers, schools and membership systems each set their own ask, and many never write it down. The honest tool isn’t the one that pretends a standard exists; it’s the one that encodes the common conventions, labels them as conventions, and gives you a custom-ratio escape hatch for whatever your issuer actually specified.

That’s the shape of the maker: six presets where exactly one (the 35×45 mm EU/ISO ID-card format) is a genuine international standard, the rest are labelled conventions, and the custom option covers the long tail.

What’s here

• The maker: upload (locally — nothing is sent anywhere), pick a preset, crop inside a head-position guide, get a background-neutrality reading, download the exact-size file plus a 4×6 print sheet at 300 dpi.
• Requirements by document type: the standard-vs-convention table — which numbers are real standards and which are starting points.
• Taking the photo at home: the eye-level, one-metre, window-light method that makes any recent phone good enough.
• Lighting and background: killing wall shadows and picking a backdrop that survives review.
• Digital vs print: pixels vs paper — file limits, formats, true-size printing, and the re-photograph trap to avoid.

How it’s built and maintained

ID Photo App is a static site on Cloudflare’s edge network — there is no image-processing server for anything to be sent to. The maker is dependency-free JavaScript that decodes, crops, samples and re-encodes inside your tab. It’s maintained by a small independent team that builds focused utility sites, and it is not affiliated with any employer, school, platform or government issuer.
