Per GB 45438-2025, write an implicit metadata label into an AI-generated image in one call, and optionally add a visible badge and an invisible watermark.
Need your AI-generated images to meet labeling requirements before publishing? This tool applies GB 45438-2025 labels: it writes an implicit file-metadata label by default and can optionally add a visible corner badge and an invisible watermark.
The service provider code is required by the standard — you can generate one quickly with the companion tool. If you turn off the default metadata label, you must enable at least the visible badge or the invisible watermark so the image still carries a compliant label.
