Add a watermark to photos you choose.
Help for the AIDWatermark iOS app.
Create watermarked photos
- Tap + and select up to 20 photos at a time with the system photo picker.
- Enter your watermark text or choose a template. Adjust opacity, density and angle.
- Preview each photo, select the results you want, then tap Save or Share.
Exports are new PNG images. Your original photos remain unchanged. A watermark can communicate a usage restriction, but it cannot prevent every form of cropping, editing or misuse.
Saving and sharing
To save results to Photos, allow AIDWatermark to add photos when iOS asks. If you declined, you can change that permission in iOS Settings. Sharing uses the system share sheet and is available separately from saving to Photos. If a source photo is stored in iCloud, your device may need a network connection to retrieve it; watermark processing takes place on your device.
