MOBI to EPUB Conversion FAQ
Is the MOBI to EPUB converter free?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
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.
How big a MOBI file can I convert to EPUB?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I convert many MOBI files to EPUB at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Does the MOBI to EPUB converter work on phones / 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 without an app.
Which browsers does the MOBI to EPUB converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses a plain `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers convert MOBI to EPUB successfully.
Are my MOBI files kept private?
+
Yes. Uploaded MOBI files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted EPUB are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy. MOBI is readable by every Kindle ever made, including the earliest hardware that never learned any newer format.
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 fails mid-download you can re-trigger from the result page without re-uploading the MOBI.
How long does MOBI to EPUB conversion take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame. EPUB reflows text to any screen size and any font size, which is what makes it readable on a phone as well as an e-reader. EPUB has no fixed pagination, so page numbers are meaningless, and complex layout — tables, equations, multi-column — degrades badly.
Do I need to install software to convert MOBI to EPUB?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no extension. Just upload your MOBI, wait, download the EPUB.
