Watermark-free pictures refer to photos or image files without copyright protection marks and watermarks. Many people like pictures without watermark, because they will not affect the visual effect and can be freely used or shared. Watermark-free pictures are also more popular on websites or social media, because they are easier to be included by search engines. However, if you use someone else's watermark-free pictures without permission, it may infringe on others' copyright or portrait rights.

In order to prevent candid shots and protect intellectual property rights, many photographers, designers and websites will add watermarks to their pictures. Watermark can be text, icon or number, which helps to identify the author and copyright information. Some watermarked pictures will be affected visually, but watermarking is still one of the effective methods to protect copyright. At the same time, for pictures or design works that need commercial use, watermarking can also help reduce the risk of piracy.

In modern society, with the development of Internet and advertising, watermark-free pictures are becoming more and more common. In order to facilitate the dissemination and use, some well-known gallery websites highlight the characteristics of no watermark, and provide watermark-free picture downloads, which is conducive to promoting freedom of speech and cultural diversity. At the same time, these websites also need to abide by copyright law and strictly protect authors and intellectual property rights. The use of watermark-free pictures should abide by the ethics and legal provisions to ensure legal and prudent use.
