Add Watermark - Protect Your Images
In the era of rapid content sharing, protecting your digital intellectual property is more important than ever. Our professional watermarking tool allows you to overlay custom branding, copyright notices, or identifiers onto your images with surgical precision. You have full control over font selection, text size, rotation, and alpha transparency—allowing you to create watermarks that act as a deterrent to theft without ruining the viewer's experience. Strategically place your name or site URL in high-detail areas of the photo to ensure it remains even after aggressive cropping. Process dozens of images in a single session, all while maintaining complete privacy.

Questions
Frequently asked questions
Can a watermark be removed?
A watermark is a deterrent, not absolute protection. Place it across detailed parts of the image if you need stronger proofing.
Does the watermark tool upload my image?
The watermark is drawn locally in the browser for supported files, so basic watermarking does not require a server upload.
What text should I use?
Use your name, brand, website URL, copyright notice, or client proof label depending on how the image will be shared.
