Watermark Tool Guide
Draw a text watermark onto a picture, choosing the corner, size, colour and opacity.
A short companion for Watermark Tool: when it is useful, what it expects, and what to check before using the result.
What it does
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.
Use the tool
Open Watermark Tool, add the input the tool asks for, run it, and check the output before using it elsewhere.
Input and output
- Input: text.
- Output: text.
- Category: Web.
Privacy and processing
Processing happens locally in your browser. This tool does not upload the input to ilham.dev.
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.
