FB2 to DOCM Converter
Processing entirely on your device — large files may take a moment.
Convert DOCM exactly like DOCX — text, tables and images extract the same way. If your files are still in FB2 format, this page is the shortcut: 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.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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 DOCM format
DOCX is the modern Microsoft Word format (Office Open XML, default since Word 2007). A file is actually a ZIP package of XML parts — document body, styles, numbering, headers, embedded media — which is what lets Word, Google Docs, LibreOffice, WPS and Pages all open it natively. Text flows around styles rather than absolute positions, so a document adapts to the page it is rendered on.
It is the format of collaboration: tracked changes, comments, styles and templates are first-class citizens, and office ecosystems assume it. The trade-off is layout drift — the same DOCX paginates slightly differently across renderers, and very complex layouts (exact positioning, text over images) can shift. For contracts in progress it is ideal; for the signed final, export a PDF.
+ Strengths
- ✓Fully editable with styles, track changes and comments
- ✓Opens natively in Word, Google Docs, WPS, LibreOffice
- ✓Flowing layout adapts to any page size
! Limitations
- −Pagination and layout shift between renderers
- −Complex layouts may not survive round-trips
- −Not suitable as a final, fixed distribution format

Frequently asked questions
Is this FB2 to DOCM 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 DOCM?
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 DOCM result afterwards?
That depends on the target: DOCM 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.
