Add your FB2 file
Drop one or more .fb2 files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Converting a .fb2 ebook to .txt carries the book's reading-order content into a different package. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting a .fb2 ebook to .txt carries the book's reading-order content into a different package. FictionBook 2.0, written to disk as .fb2, is an XML ebook format that describes a book's structure — chapters, epigraphs, poems, citations — rather than its visual appearance. Because everything including images lives in one XML document, an .fb2 file is easy to parse, validate, and transform.
A .txt file is plain text: nothing but a sequence of characters and line breaks, with no fonts, styles, or embedded objects. It is the lowest common denominator of documents — every computing device of the past several decades can open one. For this route the practical draw is opens everywhere, indefinitely — no format rot possible and the smallest possible representation of textual content — balanced against no formatting, images, or tables of any kind, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .fb2, base64-encoded images inflate the uncompressed size by roughly a third. Switching to .txt buys you opens everywhere, indefinitely — no format rot possible, which is why it is the better fit for notes, to-do lists, and drafts that must outlive any particular app. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | FictionBook ebook (.fb2) | Plain text (.txt) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | a single well-formed XML file; binary resources such as cover art are embedded as base64 inside binary elements | no internal structure at all — bytes plus an assumed text encoding are the entire format |
| Strongest at | ebook distribution in Russia and Eastern Europe, where it is a native store format | notes, to-do lists, and drafts that must outlive any particular app |
| Weak spot | base64-encoded images inflate the uncompressed size by roughly a third | no formatting, images, or tables of any kind |

Select .txt in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TXT is selectable, the route is real and validated.
Press Convert. The book package is parsed in your browser in spine order; DRM-free files only, and nothing is uploaded.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TXT file. Outputs keep the original filename with the .txt extension.
There is no visual quality to lose — fb2 is text-oriented and txt is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Yes — the .fb2 file is processed inside your browser tab and never uploaded. The book package is parsed in your browser in spine order; DRM-free files only, and nothing is uploaded. Close the tab and the file is gone from memory.
Notepad, TextEdit, every code editor, every browser, and every phone open .txt without hesitation. It is the one document format with genuinely universal support across operating systems and decades.
It depends on the content: no internal structure at all — bytes plus an assumed text encoding are the entire format. Convert one representative file first and compare before batch-processing a large set.
In .fb2, a mandatory description block records title, authors, genres, language, translator, and publishing history in structured XML — richer than most rival ebook formats. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
