Question 1

How do I add a watermark to my photo?

Accepted Answer

Upload your image, type your watermark text, then customize font size, color, opacity, position and rotation. The preview updates instantly and you can download the watermarked image as PNG.

Question 2

Is my photo uploaded to a server?

Accepted Answer

No. All watermark processing happens entirely in your browser using HTML Canvas. Your photos never leave your device.

Question 3

Can I add a tiled (repeating) watermark?

Accepted Answer

Yes. Enable Tile mode to repeat your watermark text across the entire image in a diagonal pattern — ideal for protecting images from unauthorized use.

Question 4

What is the best opacity for a watermark?

Accepted Answer

A watermark opacity of 30-50% is usually best. It’s visible enough to deter theft but subtle enough not to distract from the image content.
