FB2 to LaTeX Converter
Processing entirely on your device — large files may take a moment.
FB2 (FictionBook 2) is the e-book format of the Russian-speaking world and many indie e-reader apps: a single XML file with strict semantic markup — sections, titles, epigraphs, poems. Readers like FBReader and older PocketBooks prefer it. Convert Markdown, Word or EPUB content to LaTeX when the destination is arXiv, a journal submission or a thesis template.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How FB2 compares to LaTeX
| FB2 | LaTeX | |
|---|---|---|
| Layout | Reflowable, semantic | Compiled typesetting |
| Editability | Any text editor (XML) | Any text editor |
| Structure | Strict FictionBook schema | Macro markup language |
| Best for | Russian-language & indie e-readers | Papers, theses, preprints |

About the FB2 format
FB2 (FictionBook 2) stores a whole book as one strictly-structured XML file: <section> for chapters, <title>, <epigraph>, <poem>, even <table>. That semantic rigour — not just styled text — is why FBReader, AlReader and older PocketBook devices favour it, and why conversions out of FB2 preserve the chapter tree cleanly.
Its weakness is reach: mainstream ecosystems (Kindle, Kobo, Apple Books, Google Play Books) do not accept it. Converting to EPUB moves the book into every modern reader; TXT/HTML covers plain reading, note-taking and long-term archiving.
+ Strengths
- ✓Strict semantic markup — chapters, poems, epigraphs
- ✓Single XML file, easy to validate and archive
- ✓Native to FBReader and many indie e-readers
! Limitations
- −Rejected by mainstream e-book ecosystems
- −Verbose XML makes files larger than EPUB
- −Metadata and cover support vary across apps
About the LaTeX format
LaTeX is how academia writes: preprints, theses, journal submissions and most of arXiv and Springer's back-catalogue are LaTeX sources. A .tex file is plain text with markup commands — \\section{…}, $math$, \\cite{…} — that a compiler turns into perfectly typeset PDF with numbered equations, cross-references and bibliographies.
Converting into LaTeX is the boring 80% of the academic workflow: your Markdown notes, Word draft or EPUB becomes a .tex skeleton with proper sectioning and math, ready to paste into the journal's template. The output here is source, not a compiled PDF — the final typesetting happens in the journal's or arXiv's own compiler.
+ Strengths
- ✓The required format for arXiv and most journals
- ✓Math, cross-references and citations as first-class citizens
- ✓Plain text — version-controllable and diff-able
! Limitations
- −Not directly viewable — needs a LaTeX compiler
- −Steep learning curve for manual editing
- −Complex layouts may need template tweaks
Why convert FB2 to LaTeX?
Converting makes sense where the strengths of LaTeX meet what FB2 cannot give you. The required format for arXiv and most journals Meanwhile Rejected by mainstream e-book ecosystems One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this FB2 to LaTeX converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for FB2 to LaTeX?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does the conversion work offline?
Yes. Once the page has loaded, the conversion itself runs entirely inside your browser — you can even disconnect and keep converting. No file ever touches a server.
Can I edit the LaTeX result afterwards?
That depends on the target: LaTeX is designed for what it does, and this converter reproduces its content faithfully rather than inventing editable structure. For heavy re-editing, work from a format built for editing and export the final version here.
