The PSD format is Adobe's proprietary format for Photoshop documents.

Format contentsEdit

Format history and limitationsEdit

Although the PSD format can be opened by all recent versions of Photoshop, newer versions have features and increased limits that may be troublesome for older versions.

PSB formatEdit

More recent versions of Photoshop can make use of the PSB (Photoshop Big) format, which is mainly designed for the larger filesizes and more powerful processing available on 64-bit systems.
