Is my file uploaded to a server?

No. This tool runs entirely in your browser via WebAssembly — your file never leaves your device. You can verify this in your browser's DevTools Network tab.

Can I see the watermark before applying it?

Yes — a live preview updates as you change text, size, opacity, position, and color.

Can I tile or angle the watermark?

Yes — center, tiled, or diagonal, with adjustable rotation.
