Brand product shots with your logo so screenshots and reposts still point back to your store.

Add a subtle handle or logo to photos and graphics before posting so shares credit the source.

Stamp a tiled "Draft" or "Confidential" watermark across scanned pages or exported images.
Frequently Asked Questions
Are my photos uploaded to a server?
No. The watermark is drawn onto an HTML5 Canvas entirely in your browser. Your photo and logo never leave your device and are never uploaded anywhere.
What is the difference between a text and a logo watermark?
A text watermark stamps a string you type, with a chosen font, size, and color. A logo watermark overlays a second image, such as a transparent PNG of your logo, scaled and positioned on top of the photo.
Can I repeat the watermark across the whole image?
Yes. Turn on tiling to repeat the watermark in a diagonal grid across the entire photo, similar to how stock photo sites protect preview images, instead of placing a single mark in one corner.
What image formats and sizes are supported?
You can upload JPEG, PNG, and WebP photos up to 50 MB. The watermarked result can be downloaded as PNG (lossless, supports transparency) or JPEG with adjustable quality from 60% to 100%.
How do I make the watermark less intrusive?
Lower the opacity slider so the watermark is visible but subtle, and use a light or dark color depending on the photo. A rotation of 30 to 45 degrees also reads clearly without covering the main subject.
Does the watermark keep transparency on PNG logos?
Yes. When you upload a logo with a transparent background, the transparent areas stay transparent and only the logo's visible pixels are drawn onto the photo.
