FAQ

Can I use a transparent PNG logo instead of text?

Yes. Choose the image watermark mode and select a PNG logo image. The transparent alpha channel will be preserved cleanly.

How can I create repeated diagonal watermarks across the whole image?

Check the 'Tile' position setting and adjust the rotation angle (e.g. 45 degrees) with semi-transparent opacity to protect full images against theft.

Does Add Watermark to Images upload my photos to a server?

No. TrueFree Tools processes all image layers directly in your local browser using Canvas APIs. None of your photos leave your device.
