About PSB

Overview

PSB (Photoshop Big) is an extension of the PSD format designed to break the barriers of the 2GB file size limit and 30,000 pixel dimension limit of standard PSD files. It is structurally almost identical to PSD but uses 64-bit offsets inside the file to support massive files up to 4 Exabytes (theoretically) and 300,000 pixels in width/height.

Technical Details

Internally, a PSB file mirrors the block structure of a PSD (Header, Color Mode, Image Resources, Layer and Mask Info, Image Data). The key difference is the bit-width of length integers; PSB uses 8 bytes (64-bit) where PSD uses 4 bytes (32-bit) for describing file offsets and dimensions.

History

Introduced in Adobe Photoshop CS (v8.0) in 2003 to support the growing needs of astronomical imaging, billboard printing, and HDR photography.

Common Use Cases

  • Billboard Design: Designing a 50-foot wide banner at 300 DPI.
  • HDR Compositing: Multi-layer 32-bit float compositions often exceed 2GB quickly.

Advantages

  • Massive Scale
  • Full Feature Set

Limitations

  • Compatibility
  • Slow
