EPUB to HTML Transformation FAQ

Is the EPUB to HTML 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.

Will the HTML be properly editable?

Yes — that is the point of converting out of EPUB. The output opens as a real document with live paragraphs, styles and tables rather than a frozen page image, so you can edit it directly instead of retyping. Heavily designed source layouts convert less cleanly than plain prose, so expect to tidy spacing on anything built on a complex grid. HTML is readable in every browser on every device with no software install, and it reflows properly on a phone screen.

Will the HTML open directly in a browser?

Yes, and the EPUB would not have. Browsers ship a decoder for HTML and none for EPUB, so an EPUB link forces a download while an HTML renders inline. That is usually the deciding factor when the file is going onto a web page rather than into an application.

Why does my EPUB file refuse to convert?

DRM, in almost every case. A protected EPUB 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. EPUB has no fixed pagination, so page numbers are meaningless, and complex layout — tables, equations, multi-column — degrades badly.

How big an EPUB file can I convert to HTML?

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 EPUB files to HTML 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 EPUB to HTML 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 EPUB and download the HTML.

Are my EPUB files kept private?

Yes. Uploaded EPUB files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted HTML are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy. 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.

What if the HTML 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 EPUB.

EPUB

EPUB constitutes a reflowable eBook format that adjusts to different screen sizes and reading preferences.

HTML

HTML (Hypertext Markup Language) is the standard language for establishing web pages. HTML files contain structured code with tags that define the structure and substance of a webpage. HTML is crucial for web development, enabling the creation of interactive and visually appealing websites.
