Learned why we need to convert EPUB to Mobi Calibre, it’s time for us to start converting. Next part, I will tell you the detailed information about converting EPUB to Mobi Mac Calibre.

How to convert EPUB files to Mobi with Calibre

Before converting EPUB files to Mobi with Calibre, we must get the tool ready. If you have not installed Calibre on your computer, please download Calibre and install it at first.

Next please follow steps below to start converting eBook format.

Step1: Run Calibre and add books to it

We can click “Add books’ button at the left navigation bar to add books, or just drag EPUB books from the folder which saves them to the main interface of Calibre. We can see the added books in the middle panel.

Step2: Convert EPUB to Mobi

If you want to convert all your added EPUB files, please press “Ctrl+A” to select all of them. And hit “Convert books” on the navigation bar, then a window below will appear, just select Mobi as output format, click “OK” button to start conversion.

Then you can see a process of converting at the bottom right corner, when it turns to “Zero”, it shows all the books have been converted successfully. Just click “Click to open” to find your converted Mobi files. Then you can send the converted mobi to Kindle .

Note: One thing I must point out is that every converted file is saved in different folders. If you have converted many EPUB books to Mobi, you may have to open many folders to find all your converted files, which is very inconvenient.

But during the conversion, if you see an alert below, which shows the file is protected with DRM and cannot convert DRMed files, to change EPUB to Mobi file successfully, you’d better remove DRM from EPUB books first and then start conversion.

So here I strongly recommend you another powerful EPUB to Mobi converter Epubor Ultimate , which has DRM decryption and eBook conversion features. It supports batch convert EPUB to Mobi. With this tool, we can convert both DRM-free and DRM protected EPUB files. And unlike Calibre, when the conversion has been finished, we need not to find converted files by ourselves, a window will pop up, which shows us all the converted files.
