How to Add Watermarks to Your Stable Diffusion Images with Watermark Extras
If you’re a Stable Diffusion user on Civitai, you’ve probably created some amazing images with custom models that you’d love to share. But how do you protect your work or give it a personal touch? The Watermarker extension for the Stable Diffusion WebUI lets you easily add watermarks to your images, keeping all the original metadata intact. Whether you’re posting on Civitai, social media, or anywhere else, this extension makes watermarking simple and customizable.
What is Watermarker?
Watermark Extras is a handy extension for the Stable Diffusion WebUI (works with AUTOMATIC1111 and Forge versions) that adds a watermarking tool to the Extras tab. It’s perfect for anyone who wants to:
Overlay a custom image (like a logo or signature) onto their generated artwork.
Adjust the watermark’s size, transparency, and position.
Set a default watermark for quick use across multiple images.
Best of all, it preserves your image’s metadata—like prompts, seeds, and model details—so you don’t lose any of that valuable info when sharing online.
Why Use Watermarker?
Protect Your Work: Add a personal mark to your images to show they’re yours.
Keep Metadata Safe: Unlike some platforms that strip metadata, your generation details stay embedded in the image file.
Customize Easily: Change how big, see-through, or where your watermark sits with simple sliders and buttons.
How to Install Watermarker
Getting started is a breeze:
Download It:
Grab the extension from its GitHub page https://github.com/Xavia1991/Watermarker
Or, download the ZIP and unzip it into your WebUI’s extensions/ folder (e.g., C:\Stable Diffusion\forge\webui\extensions\).
Install via WebUI (Alternative):
Open the WebUI, go to the Extensions tab, click Install from URL, paste the GitHub URL above, and hit "Install."
Restart: Close and reopen the WebUI (e.g., run webui.bat on Windows).

How to Use Watermark Extras
Watermarking your images is super easy with this extension. Here’s how:
Open the Extras Tab:
In the Stable Diffusion WebUI, go to the Extras tab.
Upload the image you want to watermark.
Set Up Your Watermark:
Click the "Add Watermark" accordion to reveal the options.
Enable Watermark: Check this box to turn watermarking on.
Watermark Image: Upload your watermark file (PNG, JPG, JPEG, or GIF). If you don’t upload one, it’ll use the default from Settings (if set).
Watermark Scale: Slide from 0.1 (small) to 2.0 (big) to adjust the size. At 2.0, it can match your image’s width or height!
Watermark Alpha: Slide from 0.0 (fully transparent) to 1.0 (solid) to set how see-through it is.
Watermark Anchor: Pick one of five spots:
Top-Left
Top-Right
Bottom-Left
Bottom-Right (default)
Center
Apply It:
Hit "Generate" to process your image with the watermark added. The original metadata stays intact!
Set a Default (Optional):
Go to Settings > Watermarks.
Enter a file path (e.g., C:\Images\my_logo.png) in "Default Watermark Image." This becomes your go-to watermark if you don’t upload one in the Extras tab.
What You Can Do with Watermark Extras
Personalize Your Art: Add a logo, signature, or any image as a watermark to make your creations stand out.
Control the Look: Make it subtle with low alpha or bold with full size—your choice!
Place It Anywhere: Choose from five positions to fit your style, whether it’s tucked in a corner or smack in the middle.
Save Time: Set a default watermark path so you don’t have to upload the same file every time.
Keep Your Details: Share your images anywhere without losing the metadata that shows how you made them.
Why It’s Awesome
Watermark Extras is all about giving you control without the hassle. It’s perfect for Civitai users who want to showcase their work while keeping it theirs.
