txt2tags to FB2 Converter
FileFlip converts txt2tags 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 txt2tags file to FB2?#
- Drop your txt2tags 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 txt2tags to FB2 lose quality?#
Not in the sense of pixels or samples. Converting txt2tags 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 txt2tags files online?#
Yes, because nothing is uploaded. FileFlip converts txt2tags 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 txt2tags file?#

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.

txt2tags to FB2 questions people ask#
What is a T2T file?
A T2T file holds txt2tags source, a lightweight plain-text markup created by Aurelio Jargas in 2001. It's meant to be compiled, not opened directly, since the txt2tags command-line tool turns one .t2t file into whichever output format the document actually needs.
What formats can txt2tags convert to?
txt2tags compiles a single .t2t source file to HTML, LaTeX, MediaWiki, DokuWiki, man pages, and several other targets, which is the whole point of the format: write once, generate whichever output a given publishing destination needs.
Is txt2tags still maintained?
Yes, though slowly. txt2tags reached version 3.9 in October 2023 under maintainer Jendrik Seipp, well over two decades after Aurelio Jargas' original 2001 release, and the format itself has changed very little in that time.
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.
