FAQ

How do I add a watermark to a photo?

Upload your image, type your watermark text, choose position (center, bottom-right, etc.), adjust opacity (30–50% is typical for subtle watermarks), and download.

What opacity should a watermark be?

For protective watermarks: 30–50% opacity keeps the image visible while making the mark clear. For copyright notices on stock photos: 60–80% opacity makes removal harder.

Is my image uploaded to a server?

No — all processing happens in your browser via HTML Canvas. Your images never leave your device.
