PNG is a versatile raster format that can be displayed in web browsers and inserted into other documents. It supports high-bit-depth color and uses a lossless compression. For maps, PNG is often the best raster format, since the lossless compression keeps text and line work legible by preventing the compression artifacts that can occur in JPEG format. PNG files also have the ability to define a transparent color; part of the image can be displayed as transparent in a web browser, allowing backgrounds, images, or colors to show through. PNGs can be generated with an accompanying world file for use as georeferenced raster data.
To export a PNG 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 PNG. 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 PNG file:
Export a layout with a transparent page instead of a white page.
Transparent backgrounds are only supported when Color depth is set to 32-bit with Alpha.
This option is not available for maps, but transparency on a map is honored on export.
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.
PNG files don't support the CMYK colorspace. If your map or layout is in this colorspace and this option is checked, the RGB color space will be embedded.
