About image watermarks

Why watermark?

A watermark discourages unauthorized reuse and signals ownership. It is especially useful for portfolios, product shots, and shared previews.

Interactive editing

After adding text you can drag it anywhere on the canvas to fine-tune the position before saving. Adjust size, color, and opacity to match your style.

FAQ

Is my image uploaded anywhere?
No. Editing runs entirely in your browser with Fabric.js. Your image never leaves your device.
Can I move the watermark after adding it?
Yes. Once added, the text becomes draggable on the canvas so you can place it exactly where you want.
What format is the output?
You get a PNG, which preserves quality and supports the watermark overlay.
