JPEGs are compressed image files. They support 24-bit color and have been a popular choice for use on the web because .jpeg file size is often substantially smaller than many other image formats. However, the JPEG compression algorithm is lossy and is not recommended for many map images, as line drawings and text or iconic graphics become blurred by compression artifacts. Thus, PNG is usually a superior format for map images. JPEGs can be generated with an accompanying world file for use as georeferenced raster data.
To export a .jpeg file, ensure that a map or layout view is active. On the Share tab, click Export Map 
or Export Layout 
, depending on the active view, to open the Export pane. Change the File Type parameter to JPEG. Set a name and location for the file, as well as any other properties, and click Export.
Note:
Certain options are only available when exporting a map or layout. When exporting a map, you can set the size of the map export. When exporting a layout, you can clip to graphics extent.
The following properties are available when exporting to a .jpeg file:
| Property | Description |
|---|---|
Show selection symbology | Show selected features in the map or map frame as selected in the output file. Unchecking this option does not affect selection within the view, only in the output file. |
Quality | The amount of image compression applied to the export. Low quality has a smaller file size but less clear data; max quality has a larger file size but crisper data. |
DPI | The resolution of the export file in dots per inch (dpi). DPI is only available when exporting a layout. When exporting a map, the dpi is calculated automatically. For map exports, increase the Width and Height values to add more pixels and get a higher-resolution output. |
Write world file | In the same location as the exported map, generate a separate world file that contains georeference information. This allows the exported image to be used as raster data in ArcGIS AllSource or other GIS applications. When exporting a layout, set Map frame to the 2D map frame you want the world file georeferenced information to be based on. This option is not available in 3D views. |
Color depth | The number of bits to describe color in a pixel. Choose from the following:
