AsciiDoc to ICML Converter
FileFlip converts AsciiDoc to ICML entirely inside your browser, using Pandoc compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an AsciiDoc file to ICML?#
- Drop your AsciiDoc file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to ICML and the conversion starts on its own. FileFlip downloads 65.8 MB of WebAssembly the first time and nothing after that, then runs Pandoc on your own machine.
- Save the ICML file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting AsciiDoc to ICML lose quality?#
Not in the sense of pixels or samples. Converting AsciiDoc to ICML rebuilds the file in ICML's own model rather than re-encoding it, so everything ICML can represent comes through exactly and anything it cannot has to be dropped. Expect the words to come through exactly and the page breaks to move.
Is it safe to convert AsciiDoc files online?#
Yes, because nothing is uploaded. FileFlip converts AsciiDoc files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What AsciiDoc to ICML actually does to the file#
Converting AsciiDoc to ICML runs on Pandoc, downloads 65.8 MB of WebAssembly the first time and nothing after that, rebuilds the file in the target's own model, keeps selectable text and page layout.
| Engine | Pandoc |
|---|---|
| Conversion path | One step: AsciiDoc → ICML |
| Downloaded to your browser | 65.8 MB, once, then cached by your browser |
| Quality | Rebuilt in the target's model |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Selectable text | Kept | Carried through into the converted file. |
| Page layout | Kept | Carried through into the converted file. |
What is an AsciiDoc file?#
An ADOC file holds AsciiDoc, a plain-text markup Stuart Rackham designed in 2002 with structural features like admonitions, includes and cross-references built into the syntax rather than bolted on afterward.
Choose AsciiDoc for technical documentation or a book that needs admonitions, includes and cross-references without hand-writing DocBook.
Convert AsciiDoc to Markdown when a document is moving to a tool or audience that only understands Markdown, accepting that admonitions, includes and cross-references have no Markdown equivalent.
What is an ICML file?#
An ICML file is a single XML document holding one InDesign story's text and its paragraph and character style names, with no page geometry, meant to be opened in Adobe InCopy or imported into an existing InDesign layout rather than viewed on its own.
Use ICML to move styled text into an InDesign layout from a source that can generate structured XML, keeping paragraph and character styles intact instead of retyping the copy.
Convert content out of ICML once it leaves the InDesign workflow, since almost nothing outside Adobe's own applications reads it.
AsciiDoc to ICML questions people ask#
What's the difference between AsciiDoc and Markdown?
AsciiDoc is a plain-text markup built for technical documentation, with admonitions, file includes and cross-references defined in the syntax itself, where Markdown has none of these without an extension or raw HTML. AsciiDoc is correspondingly more to learn, and far fewer tools render it without going through a processor like Asciidoctor first.
What program opens an ADOC file?
An ADOC file is plain text, so any text editor opens it, but seeing it rendered means running it through Asciidoctor or an editor with an AsciiDoc preview plugin, such as VS Code's AsciiDoc extension or IntelliJ IDEA's AsciiDoc plugin. GitHub also renders .adoc files directly in a repository.
Does AsciiDoc convert cleanly to Markdown?
Basic AsciiDoc, headings, paragraphs, lists, emphasis, converts to Markdown with little loss. Admonition blocks, include directives and cross-references have no Markdown equivalent, so a conversion either drops them or flattens them into plain text and a broken link.
What application opens an ICML file?
Adobe InDesign and Adobe InCopy are effectively the only applications that open ICML files, since the format exists specifically to move a story's styled text between the two. There is no independent viewer for it outside Adobe's publishing tools.
