Watermark Tool
Draw a text watermark onto a picture, choosing the corner, size, colour and opacity.
Watermark
The text is drawn straight onto the pixels, so it survives sharing and screenshots. The size is a percentage of the shorter side, which keeps it in proportion on a wide or a tall picture.

History for this tool
The most recent data you entered in this tool, stored only in this browser.
Save what you type here, in this browser? Your work would go into this browser's local storage, so a refresh or a trip to another tool does not wipe it. You also get a short list of previous entries under the form, each one restorable with a click. Nothing is ever uploaded, and there is no account.
Being straight about the trade-off: anything kept there can be read by anyone who can use this browser profile, and by any script that later runs on this site. A tool page can hold a private key, a password or a signed token. Saving is convenient; it is not private.
About this tool
Put a name, a site or a date onto a picture so it travels with the image. You choose a corner, a size as a share of the shorter side, a colour and an opacity, and the text is drawn into the pixels when you download.
Questions
- How large should the watermark be?
- Four per cent of the shorter side is small enough to stay out of the way but large enough to read on a phone. Raise it toward ten per cent when the picture will be shown at a large size.
- Why is there a dark outline?
- White text disappears on a bright sky and black text disappears in shadow. A thin dark stroke around the letters keeps them readable on either, and it can be turned off when the background is known.
- Can someone remove the watermark?
- The text is part of the pixels rather than a separate layer, so removing it means editing the image. A determined person still can, which is why a watermark deters rather than prevents.
