Understanding PCX and ICO Formats

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

Source Format

PCX Image

image/x-pcx

PCX (PiCture eXchange) is one of the earliest widely used bitmap image formats, originally developed by ZSoft Corporation for its PC Paintbrush program in the 1980s. It uses a simple run-length encoding (RLE) compression scheme and supports color depths from 1-bit to 24-bit. PCX was once the dominant bitmap format on DOS and early Windows platforms but has been largely superseded by PNG and JPEG.

Advantages

  • Simple RLE compression is fast to encode and decode
  • Lossless compression preserves image quality
  • Widely supported by legacy imaging software

Limitations

  • Largely obsolete, replaced by modern formats like PNG
  • RLE compression is inefficient for complex photographic images
  • Limited to 24-bit color with no alpha transparency support

Common Uses

  • Legacy application compatibility and file conversion
  • Historical document archival from older systems
  • Retro computing and DOS-era software

Target Format

ICO Image

image/x-icon

ICO is an image format used to store icons in Microsoft Windows and for website favicons. A single ICO file can contain multiple images at different sizes and color depths, allowing the operating system or browser to select the most appropriate version. ICO files support sizes from 16x16 up to 256x256 pixels with up to 32-bit color depth including alpha transparency.

Advantages

  • Can store multiple resolutions and color depths in a single file
  • Universal support as favicons in all web browsers
  • Native format for Windows application and system icons

Limitations

  • Limited to relatively small image dimensions (max 256x256)
  • Larger file sizes than PNG when embedding multiple resolutions
  • Primarily Windows-centric with less relevance on other platforms

Common Uses

  • Website favicons displayed in browser tabs and bookmarks
  • Windows application and shortcut icons
  • Desktop and toolbar icons in Windows environments
