AsciiDoc to Org Converter
FileFlip converts AsciiDoc to Org 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 Org?#
- 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 Org 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 Org file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting AsciiDoc to Org lose quality?#
Not in the sense of pixels or samples. Converting AsciiDoc to Org rebuilds the file in Org's own model rather than re-encoding it, so everything Org 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 Org actually does to the file#
Converting AsciiDoc to Org 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.

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 Org file?#
An ORG file holds Org mode markup, Carsten Dominik's 2003 outlining format for Emacs where headings can double as a to-do list, an agenda entry and, through Org Babel, an executable code block, none of which survive being read as plain markup elsewhere.
Use Org mode inside Emacs for notes that mix prose, a to-do list and code you actually want to run, not just display.
Convert Org to Markdown or another format when sharing the content outside Emacs, since the agenda, TODO states and live code execution have nowhere to go in plain markup.
AsciiDoc to Org 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 is an ORG file and what opens it?
An ORG file is plain text written in Org mode, Emacs' outlining and notes format, so any text editor shows the raw markup. Reading it as intended, with folded headings, clickable links and a working agenda, means opening it in Emacs, which has Org mode built in.
