EPUB to CBZ Transformation FAQ
Is the EPUB to CBZ 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.
How big an EPUB file can I convert to CBZ?
+
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 CBZ 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 CBZ 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.
Which browsers does the EPUB to CBZ 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 conversion servers, no person reviews them, and they are never shared. The upload and the converted CBZ are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
What if the CBZ 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.
How long does EPUB to CBZ 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.
Do I need to install software to convert EPUB to CBZ?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no extension. Just upload, wait, download.
Can I convert EPUB to CBZ without an account?
+
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.
