# Create an HAR File

An HAR file (History Activity Report) is a log file generated by web browsers that records browsing history, including URLs, timestamps and other details. HAR files can be used to understand browsing patterns, diagnose issues or analyse web performance. The HAR files can provide valuable information to our technical support teams when troubleshooting complex issues.

When contacting Zeotap Support with you HAR file, kindly provide a concise and comprehensive description of the issue, complemented by relevant screenshots. Note that if the HAR file exceeds a shareable size, then we suggest compressing it before forwarding it to us.
The HAR file can capture Personal Identifiable Information (PII) that you enter into your browser. To protect your privacy, ensure that you exclusively perform actions related to your support concern when generating the HAR file.
Below, you can find information about creating HAR files for some of the commonly used browsers.
