Add Watermarks to Images
Apply brand watermarks or copyright overlays to images for protection and brand consistency.
Quick answer: Use the Image Ops tool through ToolRouter to add watermarks to images directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolWatermarking is essential for protecting visual intellectual property while still being able to share and distribute images publicly. Photographers, designers, and content creators need to mark preview images with their brand to prevent unauthorized use, while marketing teams need consistent brand watermarks on assets shared externally.
ToolRouter's transform_image skill can overlay text or image watermarks with precise control over position, opacity, size, and style. You can add a subtle corner logo, a diagonal text overlay, or a repeating pattern depending on your protection needs. The watermark settings can be standardized across your entire image library for brand consistency.
This is especially important for businesses that share product images with retailers, distribute press photos, or showcase portfolio work online. The watermark protects the image while still allowing viewers to evaluate the content. Automated watermarking ensures every image that leaves your organization carries your brand, without relying on manual processing.

Claude makes watermarking an iterative terminal workflow. Describe your watermark requirements -- logo placement, opacity, style -- and Claude asks clarifying questions about the intended use case before applying. Preview the result on a test image first, adjust positioning and transparency with conversational feedback, then batch-apply the finalized settings across your library.
