Quickly Save Individual Layers as a PNG

In Photoshop CC 2015 and newer, you can right-click on a layer and chose “Quick Export as PNG” to save individual layers in your document as a PNG.

You can also export as a JPG, GIF, or SVG by changing the default export file type. To do so, open the preferences panel Ctrl K (Mac: Command K). Under the Export tab use the drop-down in the Quick Export Settings to select a different file type.
