Source format

What is TEX?

LaTeX Source (.tex). A .tex file is LaTeX source: plain text with commands that the TeX typesetting system turns into a finished document. It is the standard for mathematics and scientific papers; converting covers text, structure and maths, while custom packages and macros may not carry over.

Common use: Scientific papers, theses, mathematics

Output format

What is FB2?

FictionBook 2 (.fb2). FB2 (FictionBook) is an XML e-book format popular in Russia and Eastern Europe. It describes a book's structure (chapters, notes, cover) rather than its layout, with the whole book in one file.

Common use: E-books, especially from Russian-language libraries
