Frequently Asked Questions

What opacity should I use for a watermark?

A good starting point is 30–50% opacity — visible enough to identify your work but subtle enough not to ruin the viewing experience. For bold branding on commercial images, 70–80% is more common.

Can I use my logo as a watermark instead of text?

Yes. Upload a PNG version of your logo with a transparent background as the overlay. The tool will composite it onto your photo at the size and position you choose.

Does the watermark permanently alter my original image?

The watermark is applied to the downloaded copy. Your original file on your device is untouched, so you can always re-watermark or share the clean original.

Can I watermark multiple photos at once?

Yes, batch mode lets you upload several images and apply the same watermark settings to all of them in one go — useful for photographers processing a full shoot.

What file format should my logo be for best results?

A PNG file with a transparent background (alpha channel) is ideal. A white or solid-color background on your logo will appear as a solid box over your photo, which usually looks unprofessional.
