With Image Conversion Profiles you can specify a profile by which images are to be transformed. They can be used to do some (limited) optimization of PDF output (but mostly for low res files), but the main purpose is to provide image output for documents and assets, used for:

  • Allowing developers to get various thumbnail / medium / high res previews of assets and/or document, formatted in the best way to be embedded into a web portal

  • Generate image ouptut of CHILI documents (as a separate output format, or for embedding in other output formats such as the mobile reader in design mode)

See ? Extracting Preview Images for an overview on how to call Image Conversion Profiles using the API.
