Source Format

Canon Raw Image

image/x-canon-cr2

CR2 (Canon Raw version 2) is Canon's proprietary raw image format used by Canon DSLR and mirrorless cameras. It stores unprocessed sensor data with full bit depth, white balance, and exposure settings as metadata rather than baked-in adjustments. CR2 files provide maximum flexibility for post-processing, preserving all the data captured by the camera sensor.

Advantages

  • Preserves complete unprocessed sensor data for maximum editing flexibility
  • Widely supported by major photo editing software including Lightroom and Capture One
  • Contains extensive EXIF metadata including camera settings and lens information

Limitations

  • Proprietary format controlled by Canon with no public specification
  • Large file sizes, typically 20-30 MB per image for modern cameras
  • Requires specialized raw processing software to view and edit

Common Uses

  • Professional and enthusiast photography with Canon cameras
  • Non-destructive photo editing and raw development
  • High-quality image archival preserving maximum sensor data

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
