AI Training Opt-Out Watermark Generator

The AI Training Opt-Out Watermark Generator helps creators, photographers, and artists protect their work by adding visible watermarks that signal images should not be used for AI or machine learning training. While metadata-based opt-out methods like robots.txt and the C2PA standard exist, a visible watermark adds an unmistakable human-readable layer of protection that survives file conversions, screenshots, and metadata stripping.

This tool offers several preset messages including "DO NOT USE FOR AI TRAINING", the Japanese equivalent "避トレーニング禁止", "NOT FOR AI/ML", and customizable copyright notices. Beyond text, you can overlay built-in SVG symbols — a robot-prohibition icon, a "NO AI" badge, or a shield icon — to convey the message without relying on any specific language.

Watermarks can be placed in four layout modes: repeating tile (which covers the entire image making it nearly impossible to crop out), centered, diagonal, or in the four corners. Adjust opacity from 10–90%, choose white, black, or red coloring, and rotate from −45 to +45 degrees. Band mode adds a semi-transparent stripe across the image for additional emphasis.

Batch processing is fully supported. Upload multiple images at once and the same watermark configuration is applied to every file. Download individually or all at once. Everything runs entirely in your browser using the Canvas API — no image data is ever uploaded or transmitted.

If you need a general-purpose text watermark, try the Image Watermark tool. To inspect or strip metadata before sharing, use the Image Metadata Viewer. For verifying file integrity after watermarking, the Hash Generator can produce checksums of your output files.

1. Click the upload area or drag and drop one or more image files (PNG, JPEG, WebP, GIF, BMP). Multiple files enable batch mode.
2. Choose Text or Symbol watermark type. For text, pick a preset message or switch to Custom to enter your own. For symbols, select from the robot-prohibition icon, NO AI badge, or shield.
3. Optionally enter a name in the copyright field and click Apply to use a "© Name" watermark.
4. Select a Position: Tile for full-image coverage, Center, Diagonal, or Corners.
5. Adjust Opacity (10–90%), Font Size (auto-scale or manual), Color (white/black/red), and Rotation (-45° to +45°) to balance visibility and aesthetics.
6. Toggle Band Mode to overlay a semi-transparent stripe for added emphasis.
7. Choose PNG or JPEG output, then click Download (or press Ctrl+Enter). For batch processing, click All to download every watermarked image. Use Copy (Ctrl+Shift+C) to send the current image to your clipboard.
