Yes — the NCX / nav.xhtml / inline TOC in the MOBI is parsed and re-emitted in the EPUB container's native TOC format. Nested chapters / sub-chapters survive the round-trip and remain clickable on every reader that supports EPUB.
Yes — the cover image and every embedded illustration in the MOBI is extracted and re-embedded in the EPUB container. We preserve original resolution and color profile; the cover is also indexed in the EPUB metadata so reader apps display it correctly in the library view.
Can I read the converted EPUB on my Kindle / Kobo / Nook?
+
Depends on the EPUB format. MOBI and AZW3 work on Kindle (Paperwhite, Oasis, Scribe). EPUB works on Kobo, Nook, Apple Books, and any reader except older Kindles. For Kindle compatibility specifically, target AZW3 (KF8) — it preserves layout better than legacy MOBI.
Does the EPUB preserve MOBI CSS styling (italics, bold, drop caps)?
+
Yes — inline CSS and stylesheet rules in the MOBI are translated to the EPUB stylesheet equivalent. Drop caps, small caps, italics, bold, and inline color all survive. Reader-side overrides (e.g. Kindle ignoring publisher fonts) are out of our control.
Yes — uploaded MOBI files are processed in isolated workers and deleted within minutes. We never read the manuscript content, store the file long-term, or share it. The full data-retention policy is at /privacy/.
