Because I had never used a conversion tool before, I thought I should choose this one as its interface was quite simple, and my decision really helped me later. During the conversion process, I got access to many useful features such as bulk conversion, date filter, preview feature, and more. It also allowed me to save the converted files at my desired location.
The only minus point I found was compatibility, as it is not compatible with Mac. I needed to convert some files on Mac as well, but it was okay because the Windows version worked really well.
