Why you should watermark every copy of your ID you send
Landlords, employers, online marketplaces, car rentals and banks all ask for a photo of your ID. It feels routine, so we send it without thinking. But that image is one of the most valuable things a fraudster can get.
How ID copies get misused
- Account fraud: a clear ID photo plus a selfie trick can be enough to open bank accounts, phone contracts or buy-now-pay-later plans in your name.
- Fake verification: scammers reuse ID photos to look trustworthy on marketplaces and dating apps.
- Leaks: your copy sits in email inboxes, chat histories and shared drives you'll never see again. When a small business is hacked, those folders go with it.
What a watermark changes
A copy that says “COPY for ACME Rentals — lease application — 21/10/2026” only makes sense for that one purpose. Anyone trying to reuse it elsewhere would have to explain the text — or try to remove it, which leaves visible traces.
How to watermark properly
- Open the document watermark tool and drop the photo or PDF.
- Write who it's for and why. Keep the date on.
- Choose the repeated layout. A single mark in the middle can be cropped away; a pattern over the whole page can't.
- Check that the data is still readable — the receiver needs it — and download.
The mark is burned into the pixels, and PDF pages are rebuilt as images, so there's no layer to delete.
Send less, too
Ask whether they need both sides, or the whole document. Black out what isn't needed — the document number, a barcode, your signature — with the redaction tool. And if you send a phone photo, wipe its location data first.
Never upload your ID to a random watermark site
It defeats the purpose. Everything on Pandoo runs in your browser: the file never leaves your device.
