Understanding PSD and PGM Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

Photoshop Document

image/vnd.adobe.photoshop

PSD (Photoshop Document) is the native file format for Adobe Photoshop, capable of storing layered images with full editing capabilities. It preserves layers, masks, adjustment layers, blend modes, text layers, vector paths, and smart objects in a single file. PSD supports color depths up to 32 bits per channel and multiple color spaces including RGB, CMYK, and Lab.

Advantages

  • Preserves all Photoshop layers, masks, effects, and editing history
  • Supports very high bit depths and multiple color spaces for professional work
  • Widely supported for import by other design and image editing applications

Limitations

  • Large file sizes, especially with many layers and high-resolution images
  • Maximum file size of 2 GB (PSB format required for larger files)
  • Full editing capability requires Adobe Photoshop or compatible software

Common Uses

  • Professional photo editing and retouching with layered workflows
  • Graphic design source files for print and digital media
  • Design handoff files between designers and production teams

Target Format

PGM Image

image/x-portable-graymap

PGM (Portable Graymap Format) is a grayscale image format in the Netpbm family, storing single-channel pixel intensity values. Like other Netpbm formats, it supports both ASCII (human-readable) and binary (compact) encoding modes. PGM is commonly used in academic and scientific contexts where simplicity and ease of programmatic manipulation are priorities.

Advantages

  • Very simple specification that is trivial to parse and generate
  • Lossless storage of grayscale image data
  • No external library dependencies required for reading or writing

Limitations

  • No compression results in large file sizes
  • Limited to single-channel grayscale images only
  • Not supported by web browsers or most consumer software

Common Uses

  • Computer vision research and academic image processing
  • Grayscale image data interchange in scientific computing
  • Input and output format for command-line image manipulation tools
