About the Watermark Tool

ResizeKit's watermark tool lets you protect your images with customizable text watermarks — from simple corner stamps to full-image diagonal tiling. Works smoothly on desktop and mobile browsers.

Watermark Modes

Corner / Edge positions: Single watermark placed at any of 9 grid positions.
Diagonal (Single): One watermark rotated diagonally across the center.
Full Image Tiling: Repeats the watermark across the entire image for maximum protection.

FAQ

Does watermarking work on mobile phones?

▼

Yes! The live preview is optimized for all screen sizes and stays fixed near the top of your mobile screen so you can see changes in real time.

Are my images uploaded anywhere?

▼

No. All watermarking happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
