Format description

Amazon's AZW3 e-book format is a successor to AZW for handling e-books on Kindle devices. Its newer features include support for more modern web standards, such as HTML5 and CSS3, allowing for better styling. Note that some AZW3 files are DRM-protected, meaning that MConverter is unable to process them.

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.
