AI Labeling & Watermark Guidelines
Visible Overlays vs Metadata
Visible watermarks are pixel badges burned into corners. This browser tool re-renders image pixels onto an HTML5 canvas to strip local EXIF/JFIF metadata and blend corner badge regions.
Provenance & Transparency
Cryptographic provenance standards (such as C2PA signatures) are maintained for content authenticity. Creators should always adhere to platform AI disclosure guidelines for synthetic media.

Frequently Asked Questions
How does this tool clean images?
The image is loaded into your local browser session and rendered onto an HTML5 Canvas. The canvas rasterizer strips EXIF/JFIF header metadata and applies localized edge-gradient blending to corner badge zones before exporting a clean PNG.
Are my images uploaded to any server?
No. All processing happens 100% locally inside your browser client memory. No files or images are sent to any external server or stored in any database.
