DocBook is a semantic XML markup language for technical documentation. It separates content from presentation, allowing multiple output formats.
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.
FreeFileConvert uses tuned encoding for DBK to FB2 conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload DBK files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized FB2 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 FB2 audio with dependable progress tracking.
DocBook documents can be transformed to HTML, PDF, EPUB, and man pages using XSLT stylesheets.
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.
Upload your document file in the DBK format from your device, Dropbox, or Google Drive.
