FAQ
Can I change the watermark's position?
The watermark is placed in the bottom-right corner, a common convention that keeps it visible without covering the center of the image.
Can I use a logo instead of text?
This tool adds a text watermark; for a logo overlay, a general image editor is needed.
Is my image uploaded to a server?
No, the watermark is drawn entirely in your browser using canvas — your image never leaves your device.
