Safe ID copy

The photo is loaded in your browser via Canvas, it doesn't go to our server. The black bars you drag over the ID number or signature get burnt into the output. On top of that the watermark is rendered: red diagonal text repeated across the whole image. You download a new JPG/PNG; your original stays put.

The approach is the same (watermark + redaction), the execution is different. The KopieID app requires DigiD, an install, and links to a government account. This tool runs in your browser, no install, no account, no registration. For heavy ID work (BSN requests at the Belastingdienst) keep using the official app. For landlord/bank purposes, this is fine.

At minimum the BSN/citizen number (back of the ID card, in the MRZ strip at the bottom of a passport) and your signature. Some advise covering the photo too, but landlords/banks may actually want to see it. What you don't need to cover: name, date of birth, nationality, gender, those are usually already in your rental/bank application form anyway.

Repeating diagonal text is harder to crop out than a straight bar. Someone who tries to reuse your KopieID despite the warning can't snip 'just past' the watermark, it runs across the whole image. Same approach the official KopieID app uses.
