Convert Indesign To Idml Updated May 2026

Run via Window → Utilities → Scripts . ❌ No direct free/converter tool can fully convert INDD to IDML without InDesign because .indd is a proprietary binary format.

#target indesign var folder = Folder.selectDialog("Select folder with .indd files"); var files = folder.getFiles("*.indd"); for (var i = 0; i < files.length; i++) var doc = app.open(files[i]); var idmlFile = new File(files[i].fullName.replace(/\.indd$/i, ".idml")); doc.exportFile(ExportFormat.INDESIGN_MARKUP, idmlFile); doc.close(SaveOptions.NO); convert indesign to idml
