What is a PSB file?

An Adobe Photoshop Large Document file, recognized by the PSB (Photoshop Big) file extension, is a manifestation of digital grandeur. The nomenclature itself hints at the expansive nature of PSB files, where “big” alludes to their voluminous reservoirs of digital data.



The architecture of PSB files closely mirrors that of standard Photoshop PSD files. Both act as containers for Adobe Photoshop images, preserving creative endeavors within their digital confines. However, it’s within the realm of substantial proportions that PSB files truly shine, accommodating the grandest of visual ventures.
