How to Turn a HAR File into a JMeter Test

Creating a HAR to JMeter JMX plan is ideal when you want load tests that mirror real user flows. Follow this quick checklist to move from capture to execution.

  1. Record the user journey in your browser and export the session as a HAR file.
  2. Upload the archive, filter noise such as static assets, and configure thread groups plus ramp-up pacing.
  3. Download the generated JMX and run it in Apache JMeter or your preferred distributed runner.

You can always revisit the dashboard to perform deeper HAR analysis online or export the same traffic as a k6 script for comparison.
