The .fb2 filename extension refers to the open XML based eBook format known as FictionBook. The file format was developed by Dmitry Gribov with an initial release in 2004, quickly gaining popularity in Russia. The format is open which in this context means it has no compatibility with digital rights management technologies. The structure of the format splits the contents of the data into three sections; title information, XML document information, and finally information about the paper edition which is optional.
From the 70's to 2007 the open source .txt filename extension format commonly referred to plain text documents encoded using the ASCII character set. To support internationalization and localization, .txt text documents are today text files encoded using the UTF-8 or UTF-16LE standard which is a superset of the ASCII character set. Text documents of type .txt typically have minimal formatting for example no support for bold or italic characters or support for bullet points etc. This allows .txt documents to use minimum storage space and be platform independent as long as the operating system supports the underlying encoding character set used to create the .txt document. On windows .txt file support has existed since 1985 when Windows 1.0 was released and since then has been mostly associated with the notepad application on Microsoft Windows.

Upload FB2 files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized TXT results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent TXT audio with dependable progress tracking.
Being extended from the XML format, the FictionBook file format describes the structure of the documents content, supporting metadata such as author, title, as well as special tags for quotations and epigraphs. Unicode is the supported character set used with the format. To display supported raster images, the images are first converted to a base 64 stream and contained within a binary tag. Plain text data typically loads first, being located at the top of the file with images allowed to load later in sequence.
Unicode (UTF-8 or UTF-16LE) is the defacto character encoding set for .txt files. It is supported by all major operating systems, with many having native applications that can open .txt documents.
