FAQ

Can I use a logo or image as the watermark?

Not in this tool, which only draws text. For a logo, use the Add Logo to Image tool, which works on one image at a time.

Why is my watermark cut off or tiny on some images?

The font size is in pixels and is the same for every image, so it looks large on a small image and small on a big photo. The text is also not wrapped or scaled to fit, so long text on a small image can run past the edge. Try a smaller size for small images or process them in separate batches.

Can someone remove the watermark?

The watermark is drawn into the pixels, so it cannot be toggled off, but a low-opacity mark in one corner can be cropped or retouched out. A centred, larger mark is harder to remove but more intrusive.

Are my photos uploaded?

No. The watermark is drawn on a canvas in your browser and the files stay on your device.
