Format description

MOBI is a Mobipocket e-book file. Even though it was originally made for the Mobipocker Reader for PDAs (now defunct), it is supported by other e-book readers. MOBI is specifically designed for low-bandwidth mobile devices. In addition to storing the contents of digital books, MOBI files may include bookmarks and DRM protection. The latter prevents creating unauthorized copies of the book and acts as copyright protection.

This app is exactly what I asked for and is super easy to use. I am not a big time computer wizard so I need apps that do what they say do in a straightforward process. This app does just that! I love it and will continue to use it and will advise others of it as well. Good job to the owners/developers! And, sincere THANK YOU!

Finally found a converter that did webp to gif without killing the animation. I tried around 12ish different converters and this is the only one that works so far. Hats off to you dev, thank you.

AMAZING! This is the perfect file converter! The first thing I used it for was to convert WMV files to MP4 and it worked flawlessly. I then realized it supports all kinds of formats and is basically unlimited. The UI is very user-friendly and super easy to navigate. Incredible app, MConverter!

Although there are occasional errors, I was very impressed with the efforts of the developers to receive feedback from users and to improve the inconveniences quickly. I will be using it more often in the future.
