Muse to FB2 Converter
FileFlip converts Muse to FB2 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 Muse file to FB2?#
- Drop your Muse 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 FB2 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 FB2 file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting Muse to FB2 lose quality?#
Not in the sense of pixels or samples. Converting Muse to FB2 rebuilds the file in FB2's own model rather than re-encoding it, so everything FB2 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 Muse files online?#
Yes, because nothing is uploaded. FileFlip converts Muse 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 Muse file?#
A MUSE file holds Emacs Muse markup, the plain-text syntax of an Emacs authoring mode that publishes a single source file to HTML, LaTeX, and other output formats.
Write in Muse when authoring inside Emacs and publishing the same document to more than one output format from a single source.
Convert Muse markup to another format when the document needs to leave Emacs, since almost nothing else reads it directly.
What is an FB2 file?#
An FB2 file is a single XML document that holds an entire book's text, metadata and base64-encoded cover images, in the FictionBook format that originated in the Russian-language ebook scene.
Keep a book as FB2 when it is sourced from a Russian-language ebook library and the reader is FB2-native, such as FBReader or a PocketBook device.
Convert FB2 to EPUB to read the book on a device or app outside the small set of readers that understand FictionBook directly.
Muse to FB2 questions people ask#
What is a .muse file?
A .muse file is written in Emacs Muse, a lightweight markup for authoring documents inside Emacs that publish to HTML, LaTeX, and other formats from one source file. It predates most of today's lightweight markups and is closely tied to the Emacs text editor.
Do I need Emacs to open a Muse file?
A .muse file is plain text, so any text editor displays it, but only Emacs with the Muse mode installed understands the markup and can publish it to HTML, LaTeX, or another output format. Converting it to a mainstream document format is the practical way to read it elsewhere.
What's the difference between Muse and Org-mode?
Both are Emacs markup languages for writing plain text that publishes to multiple formats, but Org-mode, created in 2003, has a far larger and more active community and covers far more ground than authoring, including task management and literate programming. Muse remains a narrower, publishing-focused tool with a much smaller following.
What is an FB2 file?
An FB2 file is an ebook in the FictionBook format, a single XML document that holds the full text, metadata and any cover image in one file rather than the zipped archive EPUB uses. It was created in 2004 and is most common in Russian-language ebook collections.
