Watermark ID Document — Protect Passports, Licenses & ID Cards
Add protective watermarks to passport scans, driver licenses, and national ID cards before submitting them for identity verification. Tiled, diagonal semi-transparent text covers portrait photos and document numbers so unauthorized parties cannot repurpose your credentials. Replace <PURPOSE> in the default watermark with your specific reason, such as bank KYC, employer I-9 verification, or hotel check-in.
Use Cases
How to watermark an ID document
Select or drag your passport, driver license, or national ID photo. Your document is processed locally in memory and never uploaded to any server.
In the watermark text field, replace <PURPOSE> with your actual recipient or reason—such as "Bank KYC", "Employer I-9 Verification", or "Hotel Check-in"—along with the date.
The default tiled diagonal layout spans across portrait photos and identification numbers, stopping cropping attempts while keeping essential fields legible.
Save the watermarked image to share with the verifier, keeping your clean original image safely stored on your device.
Frequently Asked Questions
- What should I replace <PURPOSE> with in the watermark text?
- Replace <PURPOSE> with the specific organization and reason you are submitting the ID for. Common examples include "Chase Bank KYC", "Acme Corp Employer I-9", "Hotel Registration", or "Car Rental Check-in". Pinning the copy to one recipient and purpose prevents identity thieves from opening loans or accounts in your name.
- Why should I watermark ID documents before sending them online?
- Plain scans of driver licenses and passports are high-value targets in data breaches and phishing scams. A clear, indelible watermark tied to a specific organization and date renders the copy useless for unauthorized credit applications or fraudulent account creation.
- Why does a tiled diagonal watermark resist cropping and editing?
- Watermarks placed only in margins or corners can be easily cropped out or digitally erased. A semi-transparent diagonal pattern repeats across your facial photo, birthdate, and ID number, ensuring that any tampering visibly breaks the document verification markers.
- Is it safe to process sensitive government IDs on this website?
- Yes. All image manipulation and canvas rendering happen 100% locally in your browser. No files, metadata, or document contents are ever transmitted over the network or saved to our servers.
- Should I keep my original unwatermarked ID photo?
- Always keep your unwatermarked master file in secure personal storage. Never overwrite it. Generate a tailored, watermarked copy for each individual entity that requests identity verification.
Your ID document or passport photo is processed entirely in your browser — images are never uploaded to a server.
