What is a HAR file?
Developed by World Wide Web Consortium, the HAR extension refers to an archive saved in the HTTP Archive format. It is a JSON-formatted file type mainly used in collecting HTTP performance data. The main task of the extension is to track the performance of web browsers. So it collects and stores information about the tracked webpages, such as their current version, response time, and the overall speed. HAR files are text-based and store metadata, which contain the format version and the name of the creator.
