Djot to Markua Converter
FileFlip converts Djot to Markua 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 a Djot file to Markua?#
- Drop your Djot 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 Markua 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 Markua file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting Djot to Markua lose quality?#
Not in the sense of pixels or samples. Converting Djot to Markua rebuilds the file in Markua's own model rather than re-encoding it, so everything Markua 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 Djot files online?#
Yes, because nothing is uploaded. FileFlip converts Djot 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 is a Djot file?#
A DJ file holds a Djot document, a lightweight markup that reads like Markdown but is built on an unambiguous grammar, so it parses the same way in every implementation.
Write in Djot when Markdown's readability is wanted without its parsing ambiguities, and broad tool support isn't a requirement yet.
Convert Djot to another format when sharing with tools or people that only handle Markdown, HTML, or another mainstream format.
What is a Markua file?#
A MARKUA file holds Markua, Leanpub's Markdown dialect for writing books and courses, adding parts, chapters, asides, quizzes and other publishing structure that plain Markdown has no syntax for.
Write in Markua when the book or course is being authored and published on Leanpub.
Convert a manuscript to Markua when importing it into Leanpub from another format, since Leanpub's build pipeline is built around it.
Djot to Markua questions people ask#
What is a .dj file?
A .dj file is a Djot document, a lightweight markup language that looks like Markdown but parses under a stricter, unambiguous grammar. It was designed in 2022 by John MacFarlane, who also created Pandoc and co-authored the CommonMark specification.
Who created Djot and why?
Djot was created by John MacFarlane, drawing on his essay 'Beyond Markdown' about the parsing problems built into Markdown and CommonMark. Djot keeps Markdown's familiar look while fixing the ambiguities that make CommonMark hard to parse efficiently, and adds features like footnotes and definition lists.
Is Djot the same as Markdown?
No, Djot only looks similar to Markdown. It derives most of its syntax from CommonMark but changes several rules to remove parsing ambiguities, so a document written for one won't reliably render correctly in the other.
What is a Markua file used for?
A Markua file holds the source of a book or course written for Leanpub, using Markua, the publishing platform's own Markdown dialect. Leanpub builds the finished EPUB, PDF and MOBI editions directly from this source.
