The main function of an image watermark is to protect the copyright and ownership of digital images by embedding a visible or invisible mark that identifies the creator or owner. It serves as a deterrent against unauthorized use, reproduction, or distribution of the image. Additionally, watermarks can be used for branding purposes, adding a logo or signature to enhance the visual identity of the content.
For example, a photographer might add a watermark to their photos before uploading them to a stock photo website to prevent others from using the images without permission. The watermark could include the photographer's name or logo, making it clear who the original creator is.
In the context of cloud services, Tencent Cloud offers image processing capabilities that can help users add watermarks to images efficiently. Services like Image Processing (IMG) allow users to automate the watermarking process, ensuring consistent branding and copyright protection across large volumes of images. This is particularly useful for businesses that manage extensive image libraries, such as e-commerce platforms or media agencies.
