PSBAdobe Photoshop Image File
Adobe photoshop saves files in two formats. Files having 30,000 by 30,000 pixels in size are saved with PSD extension and files larger than PSD upto 300,000 by 300,000 pixels are saved with PSB extension known as “Photoshop Big”. More specifically, PSB files can be as large as 4 EB (over 4.2 billion GB) with images that have a height and width of up to 300,000 pixels. PSDs, on the other hand, can be at maximum upto 2 GB and image dimensions of 30,000 pixels.
