VimWiki to FB2 Converter
FileFlip converts VimWiki 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 VimWiki file to FB2?#
- Drop your VimWiki 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 VimWiki to FB2 lose quality?#
Not in the sense of pixels or samples. Converting VimWiki 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 VimWiki files online?#
Yes, because nothing is uploaded. FileFlip converts VimWiki 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 VimWiki to FB2 actually does to the file#
Converting VimWiki to FB2 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 a VimWiki file?#
A file with VimWiki's default .wiki extension holds a page in VimWiki's markup, the syntax the VimWiki plugin uses to turn a folder of plain-text files into a personal wiki inside Vim.
Keep notes as VimWiki while they're actively edited inside Vim, where the plugin provides links, checkboxes, and folding for free.
Convert VimWiki files to another format to share notes with someone who doesn't use Vim, or to publish them somewhere VimWiki's own HTML export doesn't reach.
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.
VimWiki to FB2 questions people ask#
What program opens a .wiki file from VimWiki?
A VimWiki .wiki file is plain text, so any text editor displays it, but the VimWiki plugin for Vim or Neovim is what turns it into a linked, navigable wiki page with folding and to-do checkboxes. Without the plugin, it just looks like text with visible markup characters.
Do I need Vim to read a VimWiki file?
No, since a VimWiki file is plain text underneath, but reading it comfortably without Vim usually means converting it to a format like Markdown or HTML first. Vim with the VimWiki plugin is what's needed to edit and navigate it as an actual wiki.
Why does my .wiki file look like Markdown instead of VimWiki syntax?
VimWiki supports three syntax dialects: its own native syntax, Markdown, and MediaWiki, chosen in the plugin's configuration rather than by the file extension. A .wiki file set to the Markdown dialect is written in Markdown syntax even though it keeps the .wiki extension.
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.
