How to convert FB2 to DOCX
- Add your .FB2 file - drop it in the box above or click to browse.
- Convert it to .DOCX in a few seconds.
- Download your new .DOCX file.
What to expect
- Layout fidelity is approximate: FB2 encodes logical structure, not page layout, so the DOCX output uses Word's default styles rather than any custom formatting.
- Embedded images and footnotes are preserved - Calibre decodes FB2's base64 images and maps footnotes to Word footnotes, though complex referencing may need manual cleanup.
- Compressed FB2 files (
.fb2.zip,.fbz) open directly in Calibre without any pre-extraction step.
Frequently asked questions
Do chapter headings survive the conversion?
Yes. FB2 section titles map to Word Heading styles (Heading 1, Heading 2, and so on) in the DOCX output.
The converted DOCX looks unstyled - is that normal?
Yes. FB2 carries minimal styling and Calibre applies Word's built-in defaults; apply a Word template or adjust styles manually if you need a specific look.
Can I edit the FB2 text before converting?
FB2 is plain XML, so you can open it in any text editor, make corrections, save as UTF-8, and then convert.
Will a `.fb2.zip` or `.fbz` file work?
Yes. Calibre opens compressed FB2 formats directly - just add the file to the library the same way as an uncompressed
.fb2.
