Add "for filing only" style text watermarks to images · anti-theft, traceable · runs locally
When applying for banking, renting or onboarding, you often submit ID card copies. Adding a watermark like "For X Bank 2026 mortgage only" prevents the ID being repurposed for loans, account opening, etc. Use tile mode with 30–50% opacity.
When sending business licenses, account-opening permits or contract scans to partners, a "for X purpose only" watermark restricts reuse. Same applies to electronic copies of diplomas, driver's licenses and passports.
In ICP filing materials, ID documents and authorization letters need watermarks. Common format: "For example.com website ICP filing only". Red tile is the recommended style across major Chinese cloud providers.
Adding author signature or domain to photos, product shots and illustrations before posting on social platforms substantially reduces direct theft. Use corner for subtle copyright marks; tile for strong anti-theft coverage.
Yes, and widely recommended. Adding a "for X use only" text watermark to an ID card photocopy or scan is an effective way to prevent the document being misused, and many regulators have published similar guidance.
Include three elements: purpose + recipient + date. For example "For X Bank 2026 mortgage only". The more specific, the harder to misuse. For website filings, use "For yourdomain.com ICP filing only".
Tile mode is safest — text is laid diagonally across the whole image and cannot be cropped out. Corner watermarks are easily cropped away. For ID cards or bank cards, use tile + semi-transparent gray for both safety and legibility.
No. All processing happens locally in your browser (Canvas 2D draws pixels directly). Image files and watermark text never leave your device. You can even use this tool offline.
Text watermarks are visible pixel changes; a skilled user can erase them in Photoshop, but it takes time and leaves traces. For everyday misuse (chat-app forwarding, hot-linking), text watermarks are deterrent enough. For removal-resistant invisible signatures, use our Hidden Watermark tool.
This tool exports PNG (lossless, sharpest edges). If the file is too large to upload or send, run it through PNG Compress to shrink further, or use PNG to JPG to switch to a smaller format.
