This article covers everything about PSB files, including how to open a PSB file and what conversion options you have to save the file in a format that is easier to open and share.

A file with the PSB (Photoshop Big) file extension is an Adobe Photoshop Large Document file. The format is nearly identical to Photoshop's more common PSD format, except that PSB supports significantly larger files, both in image dimension and in overall size.

More specifically, PSB files can be as large as 4 EB (over 4.2 billion GB) with images that are up to 300,000 pixels high and wide. PSDs, on the other hand, are limited to 2 GB and image dimensions of 30,000 pixels.

Some subtitle files use the same file extension, but they are text files used by the PowerDivX multimedia player as the format for storing subtitles.
