Instructions
- Choose image and enter Watermark text.
- Set Position, Opacity, Text size and Text colour; click Create output.
- Inspect the preview and save the PNG download.
Understanding your result
Watermark text such as SAMPLE appears as visible pixels in the downloaded PNG. Position and Opacity affect how clearly it is seen. Check it against both light and dark areas of the image before sharing the copy. A watermark does not restrict access to the file.
What to do if you have a problem
If the label is clipped or difficult to read, shorten Watermark text, change Position or adjust Text size and Text colour. Click Create output after changing options. Keep the original for future edits because the saved watermark becomes part of the image pixels.
What to know before using the result
Processing happens on this device. Keep your original file. Images are limited to 20 MB and 16 million decoded pixels; animation and original image metadata are not preserved.
