Keep the label short
A short name or web address is easier to read at multiple image sizes than a full paragraph.
Use only a label you have the right to place. A watermark does not establish that the underlying image belongs to you.
Choose contrast and placement
Check the label over both light and dark areas. The tool adds a subtle outline to help separate text from the image, but busy backgrounds can still reduce readability.
Keep the main subject visible. A large opaque watermark may obscure information or make an image harder to use.
Understand the saved result
The watermark is drawn into raster pixels; it is not stored as an editable text layer. Keep the original and source text separately.
A visible mark can be cropped, blurred, or removed. Use appropriate licensing, contact details, or rights-management processes for stronger protection.
Common questions
Can a watermark stop someone from copying an image?
No. It can deter casual reuse or identify a source but is not technical access control.
Will the watermark preserve the original file's metadata?
The exported canvas image is a new raster file and should not be relied on to retain original metadata.
