Protect copies of your ID
Landlords, letting agents, employers, banks and online services often ask for a copy of your passport, driving licence or ID card. Once you've sent it, you can't control where it goes. If a copy is leaked or stolen, a clean scan can be reused for identity fraud.
A watermark that says who the copy is for and when it was sent makes it far less useful to anyone else. Choose the ID / passport copy preset and replace [who], for example "Copy for ABC Lettings only · 26/10/2026". The tiled layout covers the whole document so it can't simply be cropped off. Keep the opacity low enough that the details stay readable, so the copy is still accepted.
Only share what's needed. If they don't need your document number or signature, drag a box over it to hide it.
Uploading your ID to a website to protect it would defeat the point. This tool runs entirely in your browser: the image is never sent anywhere.
Watermarking photos and product shots
- Photographers: a small corner watermark or a faint centred logo on proofs and previews.
- Online sellers: a shop name on listing photos so they're harder to copy.
- Documents: "Draft", "Confidential" or "Sample" across every page of a PDF.
Add as many files as you like; the same watermark is applied to all of them, and several files download together as a ZIP. Re-saving photos also removes hidden location data.
PDF watermarks: overlay or flatten?
By default the watermark is added as a transparent layer on each page, and the original text stays sharp and selectable. That's right for drafts and confidential documents. For ID copies and anything you want to be hard to tamper with, tick Flatten: each page becomes a single image with the watermark baked in, so it can't simply be deleted in a PDF editor.
FAQ
Can a watermark be removed?
No watermark is impossible to remove, but a tiled watermark across the details, flattened into the image, takes real effort to remove cleanly. That's usually enough to make a stolen copy not worth using.
Does it work with any language?
Yes. The watermark is drawn with your device's fonts, so any language or symbol your device can display works.
Is the pixelation safe for hiding numbers?
The pixelation is very coarse, so individual characters can't be read. For the strongest protection, choose "Black box".
