Free ComfyUI Workflow: Batch Watermark Remover & Adder with AI

Managing watermarks on images is a tedious, time-consuming task. Whether you're cleaning up source material or protecting your own creations, editing photos one by one is a workflow killer. This ComfyUI workflow is the ultimate solution, offering a powerful, one-click method to both remove and add watermarks across multiple images at once.

Forget manual masking and cloning. This advanced pipeline uses a combination of cutting-edge AI—SAM (Segment Anything Model) and GroundingDINO—to intelligently identify, segment, and inpaint over unwanted watermarks with incredible precision. For adding watermarks, it provides a streamlined process to apply your logo or text to an entire batch of images, saving you hours of work.

The AI Magic: How It Works

This workflow's power comes from its intelligent segmentation and inpainting process.

• GroundingDINO: You tell the AI what to find with a simple text prompt, like "watermark" or "logo." GroundingDINO scans the image and locates the object that matches your description.
• SAM (Segment Anything Model): Once GroundingDINO finds the watermark, SAM creates a pixel-perfect mask around it. This ensures that only the targeted area is affected, protecting the rest of your image.
• Inpainting: With the watermark perfectly masked, an inpainting model takes over. It intelligently rebuilds the area underneath the mask, seamlessly blending it with the surrounding image to make it look like the watermark was never there.

How to Use the Watermark Remover

This workflow makes removing logos, text, and other unwanted elements incredibly simple.

1. Load Your Image: Use the Load Image node to upload the photo containing the watermark.
2. Tell the AI What to Find: In the text prompt input for GroundingDINO, simply type what you want to remove (e.g., "watermark", "text logo", "person").
3. Queue Prompt: Run the workflow. The AI will automatically detect, mask, and inpaint the specified area, generating a clean version of your image.
4. Save the Result: The final, clean image is sent to the Save Image node, ready for you to use.

How to Add Watermarks in Bulk

Protecting your work is just as easy and can be done for an entire folder of images at once.

1. Load Your Images: Use the Load Image List From Dir node to select the folder containing all the images you want to watermark.
2. Load Your Watermark: In a separate Load Image node, upload your logo or watermark image (preferably a PNG with a transparent background).
3. Position and Apply: The workflow will overlay your watermark onto each image from the folder. You can adjust the position and scale within the workflow's nodes.
4. Save the Batch: The final watermarked images will be saved automatically, typically with a prefix or suffix to distinguish them from the originals.

Frequently Asked Questions (FAQ)

What custom nodes are required for this workflow? You will need nodes for GroundingDINO and SAM, which are often found in the "Grounded-Segment-Anything" custom node pack. You can install this through the ComfyUI Manager.

**How accurate is the watermark detection?**Thanks to GroundingDINO, the detection is highly accurate. It works best with clear text prompts that describe the watermark. For complex or semi-transparent watermarks, you may need to adjust the detection threshold within the node's settings.Can it remove things other than watermarks? Absolutely! This is a powerful object removal tool. You can use it to remove people, objects, text, or any other element from an image by simply changing the text prompt.

Is it legal to remove watermarks? You should only use this tool on images that you have the legal right to modify. Removing watermarks from copyrighted images without permission can infringe on the creator's rights. Use this workflow responsibly.
