EPUB to ZIP Conversion FAQ

Is the EPUB to ZIP 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 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.

Will the ZIP be much smaller than the EPUB files that went into it?

Barely smaller, and that is expected. An EPUB already holds its contents in compressed form, so general-purpose compression has almost nothing left to find and the archive lands within a few per cent of the total it was given. Pack it anyway for the reasons that have nothing to do with size: one file to send instead of forty, one download, one checksum, and the folder layout preserved on the way out. An EPUB is a ZIP archive of XHTML and CSS with a manifest — essentially a small website packaged as a book.

Is there any point putting an EPUB inside a ZIP when it is already an archive?

For handling rather than for size. An EPUB is a ZIP container with a different extension and a required internal layout, so wrapping it in another one compresses essentially nothing — the second layer is there to bundle several files into one, to survive a mail system that mangles unusual extensions, or to stop a browser trying to open the file instead of downloading it. Unpacking gives back the original file untouched, not its insides.

How big an EPUB file can I convert to ZIP?

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 ZIP 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 ZIP 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 EPUB to ZIP converter support?

Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers work.

Are my EPUB files kept private?

Yes. Uploaded EPUB files are processed on our own servers and are never viewed or shared. Uploads and results are deleted automatically about 24 hours after conversion. See /privacy/ for the full policy.

What if the ZIP download doesn't 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 EPUB.

EPUB

EPUB is known as a reflowable eBook format that adjusts to different screen sizes and reading preferences.

ZIP

ZIP is a widely used compression and archive format. ZIP files group a variety of files and folders into a single compressed file, reducing storage space and facilitating easier distribution. They are commonly used for file compression and data archiving.
