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.
Images are usually compressed with PackBits, or uncompressed. "Zip" compression, by which it apparently means zlib, is also supported.
