Image Watermark

Add a text or logo watermark to an image with custom placement, tiling, rotation, opacity, and PNG, JPEG, or WebP output.

How to use

1. Upload the source image.
2. Upload a logo to watermark, or enter watermark_text.
3. Adjust the options and run the model.

Options

• Place one watermark in a fixed or custom position.
• Repeat the watermark with mode=tiled.
• Adjust scale, opacity, rotation, spacing, margin, shadow, and backing plate.
• Render Latin or CJK text when no watermark image is provided.

Notes

• If both a watermark image and text are provided, the image takes priority.
• Use PNG or WebP when transparency matters; JPEG uses a white background.
• Metadata preservation is disabled by default for privacy.
• Images are limited to 50 million pixels and 4,096 tiled elements.
• This adds visible watermarks and is not proof of ownership.
• Only process images you have the right to use.
