IDML (InDesign Markup Language): This is an open-source, XML-based format. Think of IDML as the "universal translator" for InDesign. It strips away version-specific metadata and saves the file’s core content—text, images, styles, and pages—into a readable code. Any version of InDesign from CS4 onward can open an IDML file. Furthermore, IDML is the standard format for importing into alternative layout software like QuarkXPress, Affinity Publisher, and Scribus. indd to idml online converter
