Frequently asked questions

Is my photo uploaded to add the watermark?

No. The watermark is drawn onto the image on a canvas in your browser, so the photo never leaves your device.

What's the difference between single and tiled?

Single places the watermark once in a corner or the center — good for a signature or logo credit. Tiled repeats it diagonally across the whole image, which is harder to crop out and is typical for protecting stock photos.

Can I use a logo image instead of text?

Not yet — this tool currently supports text watermarks only.
