网之映 is a short-link service that helps individuals and businesses create concise URLs for sharing and campaign tracking. Its online generator offers free link creation, with tools designed to support fast redirects and reduce the likelihood of links being blocked on platforms such as WeChat and QQ. The service is intended for social media promotion, SMS marketing, e-commerce referrals, affiliate campaigns, and QR codes used on printed materials.

Users can access API tools for batch link generation, add a custom dedicated domain, and choose from several redirect methods. Professional plans include access statistics such as page views, unique visitors, geographic distribution, and traffic sources, while enterprise customization is also available. The site describes its infrastructure as cloud-accelerated and reports handling more than two million redirect requests per day. In addition to short-link creation, 网之映 offers external-link QR code services and a short-link system for purchase. The company states that its service is free to use and asks users not to create links to prohibited content, which it says may be removed and reported to relevant authorities.
