The Image Watermark Adder is a private, client-side utility designed to safeguard your documents and digital media. Whether you are submitting identity documents with "FOR VERIFICATION ONLY" notices or protecting photography portfolios with copyright stamps, this tool processes everything right on your computer.
Protect identity cards and certificates before uploading them to job portals, banks, or rental applications.
Repeated 45° tiled watermarks make document manipulation or unauthorized cropping virtually impossible.
Your sensitive photos never leave your device. The rendering runs entirely within HTML5 Canvas in browser memory.
Recommended Watermark Practices
Government & Bank Verification
When submitting Aadhaar, PAN, or Passport scans, write the exact recipient and purpose: "FOR VISA APPLICATION ONLY - JAN 2026".
Creative Portfolios & Mockups
Use a semi-transparent (40-60% opacity) center stamp or bottom-right signature to discourage image scraping without obstructing design review.
