📖 What is Image Watermark?
Image watermarking is a technique of adding text or image identifiers to images, used to protect copyright, identify sources, or increase brand exposure. Haoyi Network's online image watermark tool supports adding text and image watermarks, with customizable position, opacity, size, rotation angle, and other parameters to meet various watermarking needs.
In the internet age, image theft is very common. Photographers' works, designers' creations, merchants' product images can all be used by others without authorization. Adding watermarks can effectively protect your original works while also increasing brand exposure.
