About watermarking here

A mark in the corner stays subtle. Tiling repeats it across the whole image, which makes it much harder to crop out or remove.

The watermark becomes part of the pixels at full quality, so it survives in every format you download.

Common questions

Is the watermark tool free?

Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.

Are my files uploaded to a server?

No. The watermark tool runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.

Where should I put a watermark so it is not annoying?

A corner at low opacity is the usual answer for photos you want people to enjoy, and it's enough to say who made it. Tiling it across the whole image is for proofs and previews you don't want used as they're. The trade is always the same: the harder a watermark is to remove, the more it gets in the way of the picture.

Can someone remove my watermark?

A corner mark at low opacity can be cropped or painted out by anyone with a little patience, so treat it as a credit rather than a lock. A tiled watermark over the middle of the picture is much harder to remove cleanly. Nothing you put into an image is truly permanent, which is why proofs are usually sent at a low resolution as well.
