# Page Load Tests

A ThousandEyes page load test measures the performance of an individual web page. This test uses a Chromium-based browser running on a Cisco ThousandEyes Cloud or Enterprise Agent. In addition to showing total page load time, the page load test shows the load times for each of the Document Object Model (DOM) components on the page.

The view for this test includes a special **Waterfall** tab that only appears for page load and transaction tests. See [Navigating Waterfall Charts for Page Load and Transaction Tests](https://docs.thousandeyes.com/product-documentation/browser-synthetics/navigating-waterfall-charts-for-page-load-and-transaction-tests) for more information.

Page load tests only work for HTML pages or XHTML applications. When you create your test, you can't point the URL to an image such as a **.jpg** or **.png** file. See [Permitted Content Types for Page Load Tests](https://docs.thousandeyes.com/product-documentation/browser-synthetics/page-load-tests/permitted-content-types-for-page-load-tests) for more information.
