What Are HAR Files

HAR, short for HTTP Archive, is a format used for tracking information between a web browser and a website. A HAR file is primarily used for identifying performance issues, such as bottlenecks, slow load times, and page rendering problems. The HAR file keeps track of each resource loaded by the browser along with timing information for each resource.
