PSD is the native layered raster graphics file format of the Adobe Photoshop program line. The format has gone through multiple versions, each being downwards (but not always upwards) compatible.
PSD is a partially-documented proprietary format. It is very large and complex. Despite this, decoding the primary image of a PSD file is often fairly simple. If an application claims to support PSD, that could mean just about anything.
 Format details
 Text encoding
PSD files often contain both Unicode and non-Unicode text. It's not clear whether there is a good way to determine the encoding of the non-Unicode text. Some sources claim MacRoman, which is true in many cases, but other encodings have been observed.
PSD files begin with bytes
'8' 'B' 'P' 'S' 0x00 0x01.
