Print and Web File Formats In Adobe Photoshop
Most of the images produced in Adobe Photoshop are destined for export. The native file format of Adobe Photoshop documents is “.psd”. This is the only format which supports all of Photoshop’s features: layers, layer masks, layer comps, etc. If you have used these features in creating your final artwork, it is always a good idea to retain the “.psd” version and use File – Save As to export your work in any other format.
