Convert FictionBook 2.0 (.fb2) e-book XML documents into clean GitHub Flavored Markdown with preserved YAML frontmatter, chapters, epigraphs, poems, and embedded illustrations directly in your browser. 100% private with zero server uploads.
Detailed side-by-side format architecture for FB2 Document (.fb2) and Markdown Document (.md). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .fb2 file onto the working surface or use the system file dialog. File magic bytes are verified locally on device.
Select a quality preset (Lossless, Visually Lossless, Balanced, Smallest) or adjust advanced encoding switches in the options panel.
Click CONVERT to execute local WebAssembly compilation. Save the finished .md directly to local storage, or stage it for chaining.
Prefer local shell scripting? Run this standard POSIX command on your machine to achieve equivalent transcoding without a web interface:
# Convert FB2 to MD locally
pandoc input.fb2 -o output.mdWorking with files across multiple web pages? The official convrtr Chrome Extension adds native Side Panel docking, right-click context menu media extraction, and visible viewport capture. Powered by the same zero-upload client-side WebAssembly engine.
FictionBook 2.0 (FB2) is an open XML-based e-book format created by Dmitry Gribov and Michael Matsnev. It encodes structured literature containing bibliographic metadata, hierarchical sections, epigraphs, poems, citations, and base64-encoded binary images directly inside a single document.
Modern personal knowledge management (PKM) systems like Obsidian, Logseq, and Notion, as well as e-readers and note-taking apps, rely on standard Markdown. Converting FB2 e-books into Markdown allows readers to annotate literature, cross-reference quotes, and build private digital libraries without proprietary e-reader software.
convrtr preserves book structure by mapping <section> and <title> tags to proportional Markdown headings (# and ##), formatting <epigraph> and <cite> as blockquotes (>), converting <poem> stanzas into formatted verse, and decoding embedded base64 <binary> cover and inline illustrations into clean Markdown images.
Never. All XML decoding, text normalization, and Markdown generation happen 100% in your browser's local memory using pure TypeScript. Your books and reading materials are never transmitted to any third party.
FB2 Document (FB2) and Markdown Document (MD) serve distinct roles across the digital workflow. Converting to MD provides optimized compatibility, modern compression efficiency, or standardized playback across web browsers, operating systems, and media production environments.
The output format (MD) is inherently lossless or supports lossless operation. Your original visual or audio fidelity is mathematically preserved without quantization artifacts.
Never. convrtr is architected with a strict zero-upload model. All processing, decoding, decompression, and encoding happen 100% locally on your machine using sandboxed WebAssembly and Web Workers. Your data never touches an external server, database, or analytics collector.
You can execute this conversion locally via command-line utilities such as ffmpeg, cwebp, or ImageMagick. For example: see the developer terminal recipe provided in the technical specifications dossier above. convrtr provides the identical local-first capability directly inside your browser without installing CLI packages.
Yes. You can drop multiple .fb2 files into the instrument to process them concurrently in browser Web Workers, or click 'Open in Master Studio' to queue mixed formats, configure individual targets, and export as a single ZIP archive.
