Frequently asked questions

Is it okay if the photos are different sizes?

Yes. Text/logo size and margins are set as a ratio of the photo's width, so they look consistent across any photo.

The logo's background comes out white.

Use a PNG logo with a transparent background. A JPG logo will include its background too.

Is the photo uploaded to a server?

No. Everything is processed in your browser, and files are never sent anywhere.

How do I make the watermark hard to remove?

Tiling it at an angle with 30–50% opacity makes it hard to crop out or remove.
