Watermark Adder

A watermark adder overlays custom text on your image to protect or brand it. You can set the watermark text, position, font size, color and opacity, then download the watermarked picture — all rendered locally with the Canvas API so your image is never uploaded.

How to Use the Watermark Adder

Select the image you want to watermark.
Enter your watermark text.
Adjust position, size, color and opacity.
Download the watermarked image.

Frequently Asked Questions

Can I control where the watermark appears?

Yes. Choose a corner or the center, and adjust size and opacity so the watermark is visible without overpowering the image.

Does it change my original file?

No. The tool creates a new watermarked copy; your original image is untouched.

Are my images private?

Yes. Watermarking is done in your browser with the Canvas API, so images never leave your device.
