EPUB to CBR Conversion FAQ
How do I convert EPUB to CBR?

Drop your EPUB file onto the upload box (or click to browse), wait a few seconds while PDF.to converts it, and download the resulting CBR file. No account, plugin, or install required.
Is the EPUB to CBR converter free?
+
Yes. Basic EPUB to CBR conversions are free for everyone on PDF.to. Paid plans unlock larger files, batch jobs, and priority processing.
Will I lose quality going from EPUB to CBR?

Quality depends on the format pair. We use the best available encoder for CBR and pass through metadata when the target format supports it. For lossy targets, our defaults aim for the smallest noticeable difference.

Free users can convert EPUB files up to 100 MB. PRO subscribers can convert files up to 5 GB and run batches in parallel.

Yes — drag any number of EPUB files onto the page at once. Free accounts process them sequentially; PRO accounts process them in parallel for faster results.
Does PDF.to keep my EPUB files?
+
No. Your EPUB uploads and the resulting CBR files are deleted from our servers within an hour of the job finishing. We do not read, index, or share their contents.
Does the EPUB to CBR converter work on mobile?
