Secure ID copy stamping
Overlay a PURPOSE mark on an ID/document photo (face & number stay readable) plus a hidden trace mark — so you can send it without it being reused for other purposes. Processed on your machine; the image never leaves it.
Everything runs on your machine — no image is uploaded to a server
When you have to send a photo of your Vietnamese ID card (CCCD) or passport to a hotel, bank, or e-commerce platform, this tool lets you overlay a stamp that states the purpose (for example "FOR HOTEL BOOKING ONLY") onto the image while keeping the face and numbers readable, so that copy can't be reused for the wrong purpose.
Each image also gets an embedded invisible forensic watermark (purpose/date/recipient) so you can tell where a leaked copy came from if it ever gets exposed. Because these are personal identity documents, all processing runs right in your browser — your files never leave your device.
How to securely stamp your ID card before sending it out
- 1Select the document photo
Upload the Vietnamese ID card (CCCD) or passport photo you need to send (JPG/PNG).
- 2State the purpose
Pick a quick template (hotel booking, bank…) or type the purpose, and add the recipient. The date is added automatically.
- 3Stamp & download
Adjust the opacity so the face and numbers stay readable, then download the PNG that carries both the visible stamp and the invisible forensic watermark.
Frequently asked questions
After stamping, can the hotel still read my ID number and see my face?
Yes. The purpose stamp is a semi-transparent overlay, and you adjust its opacity so the recipient can still verify your face and numbers — it just makes that copy hard to reuse for a different purpose.
Does the tool send my ID card photo anywhere?
Everything runs right in your browser — your files are never uploaded to any server, keeping them completely private.
What if the image gets leaked?
Each image comes with an embedded invisible forensic watermark (purpose/date/recipient). When needed, use the Invisible Watermark tool to read it back and find out where the leaked copy came from.
