ID Photo (idphoto.bnj.app) is a web tool that turns an ordinary photo into a passport, visa or ID photo at the exact size an official standard requires. The user picks a photo from their device; the browser measures the face (chin, eye line, top of the head), levels the eyes, and crops/scales the image so the head height and eye-line position match the chosen country standard (Türkiye, United States, Schengen/EU, United Kingdom, Canada, Australia, Japan, India, China, plus a generic ICAO 35x45 mm size). It also runs measurable compliance checks (head size, resolution/effective DPI, head tilt, face angle, eyes open, mouth closed, sharpness, exposure, background uniformity) and shows a report. ALL IMAGE PROCESSING HAPPENS LOCALLY IN THE BROWSER using WebAssembly models (MediaPipe face landmarks and person segmentation) that are downloaded from our own server and executed on the user's device; photos are never uploaded, never transmitted, never stored on any server. Free tier: measuring, all country standards, the full on-screen compliance report and a watermarked, reduced-size preview download. Paid tier (subscription: 24-hour free trial, then weekly / monthly / yearly plans billed through Stripe): watermark-free downloads at true print resolution (300/600 DPI with DPI written into the JPEG), printable sheets (10x15 cm and A4 with cut marks), background replacement, a printable compliance report, batch export of several standards at once, JPEG and PNG output. There are NO user accounts, NO passwords and NO email sign-up: after payment the user gets a licence code in the form BNJ-XXXXXXXX which is stored in their browser localStorage and can be typed on another device to restore access. The site is not affiliated with any government; it follows published official photo requirements but the reviewing authority makes the final decision. The tool must not be presented as an official approval service.
