Add Watermark to Images
Watermark a whole batch with your text or logo. You control opacity and placement.
Last updated
A watermark deters casual reuse of your product photography and keeps your brand attached to images as they get shared around. The trick is making it visible enough to matter without ruining the photo.
Set your text or upload a logo, then tune opacity, size, rotation and placement in the left panel. Around 50% opacity in a corner is the usual sweet spot. Every image in the batch gets the same treatment.
How to use it
- 1Drop your images onto the tool above.
- 2In the left panel (open on Watermark), enter your text or upload a logo.
- 3Adjust opacity, size, rotation and placement until it looks right.
- 4Download the watermarked batch as a ZIP.
Frequently asked questions
How do I add a watermark to many photos at once?
Add the whole batch, configure the watermark once, and it is applied identically to every image. There is no per-file work.
Should I watermark my product photos?
It depends where they are going. On your own site and social channels it deters casual copying. On marketplace listings it is usually a bad idea, and Amazon prohibits watermarks on main listing images outright.
What opacity works best for a watermark?
Around 40–60%. Below that it disappears against busy backgrounds; above it, it starts competing with the product itself.
Can I use my logo instead of text?
Yes. Switch the watermark type to image and upload a logo. A transparent PNG works best, since it blends over the photo without a visible box.
Does watermarking reduce image quality?
The watermark is composited before the final encode, so there is no extra compression pass. Output quality matches whatever you set in the Format panel.
