Foire aux questions

Is my original image overwritten or modified on a server?

No. The watermarked image is rendered locally in your browser memory. Your original file remains untouched on your device.

Can I create a repeated pattern watermark across the entire image?

Yes! Select the 'Tile Grid' position option to automatically repeat your text or logo watermark across the entire image canvas.
