Add your MOBI file
Drop one or more .mobi 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 .mobi ebook to .md 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 .mobi ebook to .md carries the book's reading-order content into a different package. The .mobi extension belongs to Mobipocket, one of the earliest commercial ebook formats and the direct ancestor of Amazon's Kindle files. A .mobi book packs compressed HTML-style markup and images into a Palm database shell, a design inherited from the handheld organizers it originally targeted.
A .md file is a Markdown document: plain text with lightweight conventions — # for headings, ** for bold, - for lists — that convert cleanly to HTML. It stays readable as raw text, which was the entire point of the design. For this route the practical draw is legible both raw and rendered and ideal for version control — diffs read like prose edits — balanced against dialect fragmentation: tables, footnotes, and highlights differ per flavor, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .mobi, dRM-protected copies cannot be converted; only DRM-free files are usable outside the Kindle ecosystem. Switching to .md buys you legible both raw and rendered, which is why it is the better fit for rEADME files and documentation in code repositories. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.

Select .md in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if MD 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 MD file. Outputs keep the original filename with the .md extension.
There is no visual quality to lose — mobi is text-oriented and md 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 .mobi 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.
GitHub, GitLab, and most developer platforms render .md automatically, editors like VS Code preview it live, and every plain-text editor can modify it. Dedicated Markdown apps exist on all desktop and mobile platforms.
It depends on the content: inline HTML is legal Markdown, providing an escape hatch for anything the lightweight syntax lacks. Convert one representative file first and compare before batch-processing a large set.
In .mobi, title, author, description, ISBN, and publisher data are carried in EXTH header records, and most conversion tools read and rewrite them. 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.
