FAQ

What opacity should I use for a subtle watermark?

For a subtle, professional watermark, use 30–50% opacity. Higher values (70–100%) make the watermark more visible and harder to remove, which is better for copyright protection.

Can I add a logo or image watermark?

This tool currently supports text watermarks only. For image-based watermarks, you can use the Text Overlay tool with a transparent PNG.

Is my image uploaded to a server?

No. All watermark processing happens locally in your browser using HTML5 Canvas. Your images never leave your device.
