MD to EPUB Transformation FAQ
How do I convert an MD file to EPUB?
+
Upload your MD file using the picker above and the converter detects the source type and runs the MD → EPUB pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions. MD is Markdown, John Gruber’s 2004 plain-text syntax for writing structured documents that stay readable as source. EPUB is the open ebook standard from the International Digital Publishing Forum, now maintained by the W3C.
Can I still edit the content after converting MD to EPUB?
+
Not the way you edit the MD. The EPUB is a delivery format: it fixes the layout so it renders identically everywhere, which is exactly why it resists editing. Keep the MD as the working copy and regenerate the EPUB whenever the content changes — round-tripping back out of EPUB always loses something.
Which Markdown dialect does this conversion use?
+
CommonMark plus the GitHub Flavored Markdown extensions, which is the combination almost every current tool understands. That matters because Markdown was never standardised in one place: tables, footnotes, strikethrough and raw HTML behave differently between dialects, and those are exactly the constructs that silently change meaning when a document moves between renderers.
Will the converted book keep its cover, chapters and table of contents?
+
Yes where both formats can express them. Cover art, chapter divisions and a navigable table of contents are structural metadata, so they carry across rather than being flattened into the text. Footnotes and index entries are the fragile parts — they degrade into inline text on targets with no anchor mechanism.
Is the MD to EPUB converter free?
+
Yes — basic MD → EPUB conversion is free with no registration required. Premium adds higher per-file size limits, more parallel batch workers, longer retention, and removes ads.
How big an MD file can I convert to EPUB?
+
Free accounts: up to 100 MB per MD file. Premium: typically 1 GB per file depending on the source type. Very large files are split into chunks server-side when the EPUB format allows.
Will conversion change the content of my MD?
+
Conversion preserves all information that both MD and EPUB can represent. Format-specific features the EPUB cannot represent (e.g. vector data in raster output, formulas in plain-text output) are rasterized or stripped — the result page lists what changed. Markdown is plain text with lightweight conventions — hashes for headings, asterisks for emphasis, hyphens for lists. An EPUB is a ZIP archive of XHTML and CSS with a manifest — essentially a small website packaged as a book.
Can I convert many MD files to EPUB at once?
+
Yes — drop multiple MD files into the upload zone and they are queued in parallel. Premium runs more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
Does the MD to EPUB converter work on phones and tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end.
Which browsers does the converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependency — so even older browsers work to upload an MD and download the EPUB.
Are my MD files kept private?
+
Yes — uploaded MD files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. The retention window is at /privacy/. Markdown is the lingua franca of documentation, README files, static site generators and note-taking apps, and it diffs cleanly in git.
What if the EPUB download does not start automatically?
+
Disable any pop-up blocker, then click the download button manually. The result link stays active for 24 hours, so if your network drops mid-download you can retry from the result page without re-uploading the MD.
