Frequently asked questions
- What format should my logo be in?
- PNG with a transparent background works best. The transparent areas of your logo will remain transparent in the watermark, allowing the underlying image to show through. SVG also works well.
- Can I control where the logo is placed?
- Yes. Choose from a 9-point grid (corners, edges, center) or use the tiled mode for full-image coverage. You can also control the size relative to the image and the margin from edges.
- How do I watermark 500 product images at once?
- Upload your logo, set the position, size, and opacity, then drop all 500 images into the upload area. They will all be processed with the same watermark placement.
