MOBI to EPUB Conversion FAQ
What does the MOBI to EPUB converter do?
+
It converts a MOBI file into EPUB format.
Will the data inside my MOBI be preserved when converting to EPUB?
+
Yes — the content is mapped to the EPUB equivalent. Format-specific extras that EPUB does not represent natively are omitted rather than corrupted.
Is the MOBI to EPUB conversion reversible?
+
You can convert the EPUB back to MOBI on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
What output quality should I expect from MOBI to EPUB?
+
Default settings target broadcast / web quality — visually identical to the source for most viewers. For archival use, pick the highest quality option in the converter settings.
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.
Why does my MOBI file refuse to convert?
+
DRM, in almost every case. A protected MOBI is encrypted and tied to an account, and no converter can decrypt it — ours included. Files you created yourself, or bought from a DRM-free store, convert without any trouble at all. Amazon stopped accepting MOBI for new publishing in 2022, and the format cannot express modern CSS, embedded fonts or fixed layout.
Is there a file-size limit when converting MOBI to EPUB?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several MOBI files to EPUB at once?
+
Yes. Drop or pick multiple MOBI files in one upload — the converter processes them in parallel and returns a ZIP of the EPUB results. There is no need to repeat the upload step per file.
What happens to my MOBI files after the conversion?
+
Uploaded files and EPUB outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
Where can I open my EPUB file?
+
EPUB opens in the standard tools for its category. Browsers and built-in OS viewers handle the common cases.
Do I need to install software to convert MOBI to EPUB?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert MOBI to EPUB?
+
No. MOBI to EPUB conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.
