What is the Watermark Image?
Watermark Image overlays text or a logo onto a photo and lets you download a PNG. Controls cover font size, opacity, rotation and placement (corners, centre or tiled pattern).
Creators use watermarks to discourage casual reuse of portfolio shots or to brand sample previews sent to clients. Because processing is canvas-based, images stay on your device.
You already have PDF watermarking elsewhere on ToolSink — this tool focuses on raster photos and graphics instead of document pages.

Frequently asked questions
Does this upload my photo?
No. Drawing and export happen in the browser canvas.
Can I watermark many images at once?
This version handles one image at a time.
What file type downloads?
PNG for predictable transparency support with logos.
Will tiling slow the page?
Large images with dense tiling do more canvas work; give it a moment on slower devices.
