What is a PSB file?

The .psb file format is a file extension for the image files edited and/ or saved in Adobe Photoshop. Files with .psb extension constitutes data for a large document format similar to a typical .psd files,but made for a larger image size. PSD has a limit of image size of 30, 000 by 30, 000 pixels. Further pixels are not supported by .psd. PSB is designed to support images larger than .psd limits.

To utilize .psb, the user should enable the PSD file support (specifically, the File Handling option) that is located in Adobe Photoshop Preferences pane. After enabling the said feature, images can now be saved using the .psb extension. PSB files can be saved as an image size up to 300,000 by 300,000 pixels. PSB files can be opened by Adobe PhotoShop CS or later. Users can edit .psb files using programs other than Photoshop by exporting .psb files in .tiff format. There are a number of image editing applications that can recognize the .tiff format.
