How to: Watermark Image
- Select your images.
- Type watermark text or choose a logo, then set position and opacity.
- Click Start and download.
Watermarks deter people from reusing your photos without credit and promote your brand when images are shared. Add a name, website or logo to a whole batch at once, privately on your device.
Common uses
- Brand product photos for an online shop.
- Protect photography portfolios.
- Mark property or rental photos with your agency name.
Tips for best results
- Tiled, semi-transparent marks are hardest to remove.
- Keep watermarks subtle so the photo is still enjoyable.
Watermark placement
A corner watermark is subtle and good for portfolios; a centred or tiled watermark is better protection for preview images. Use 20–40% opacity so the photo remains enjoyable.
