# MHTML Device Information Settings
The following table lists the device information settings for rendering reports in Web archive (MHTML) format.
|Setting|Value|
|-------------|-----------|
|**JavaScript**|Indicates whether JavaScript is supported in the rendered report.|
|**OutlookCompat**|Indicates whether to render with extra metadata that makes the report look better in Outlook. The default value is `true`.|
|**MHTML Fragment**|Indicates whether an MHTML fragment is created in place of a full MHTML document. An MHTML fragment includes the report content in a TABLE element and omits the HTML and BODY elements. The default value is `false`.|
|**DataVisualizationFitSizing**|Indicates data visualization fit behavior when inside a tablix. This includes chart, gauge, and map.
The possible values are **Approximate** and **Exact**.
The default value is **Approximate**. If the setting is removed from the **rsreportserver.config** file then the default behavior is **Exact**.
Enabling **Exact** may have performance impact because the processing to determine the exact size may take longer.|
