JPEG files 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.
The following properties are available when exporting to a JPEG file:
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.
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 additional pixels and get a higher resolution output.
The number of bits to describe color in a pixel. Choose from the following:
Embed color profile
Include the color profile set for the map or layout in the exported file. This helps create consistency in colors when the file is viewed on different devices. If the profile is not embedded, or a non-color-managed viewer is used, the colors may be significantly different than what is seen on-screen.
This option is only available when color management is enabled. If color management is not enabled and your colorspace is set to CMYK, the CMYK colorspace is still included in the export. This may cause some colors to appear differently when viewing the exported file.
