# Add Watermark to Image

Stamp custom text or image watermarks with precise opacity, rotation and positioning. Free, private, and processed locally without uploading files.

## What is Add Watermark to Image?

Protect your creative photography and intellectual property from unauthorized copying. Stamp semi-transparent copyright notices, names, URLs, or PNG company logos directly over your photos.

## How to use Add Watermark to Image

1. **Add your file or input** — Choose a supported file, drag it onto the upload area, or type/paste the data this tool works with.
2. **Adjust the options** — Pick the output format, quality, size or other settings the tool offers. Defaults work well for most files.
3. **Process and download** — Run the tool and save the result. Processing happens in your browser, so nothing is uploaded to a server.

## Frequently asked questions

### Can I watermark multiple photos simultaneously?

Yes. Set your watermark text, font, opacity, and positioning once, and apply it in batch mode across all selected photos in your browser.

### Does the watermark support custom transparent PNG logos?

Yes! You can upload a company logo PNG with an alpha channel, scale it, adjust opacity, and position it in any corner or center of your image.

### Can someone easily erase a stamped watermark?

Once exported, the watermark pixels are permanently flattened and merged into the underlying raster photo, making removal without visible distortion extremely difficult.
