About the formats

File extension .m4a
Category Audio file formats
Developed by Apple
Mime type audio/m4a

Format description

M4A files store audio using the AAC codec. M4A stands for MPEG-4 Audio. It is very similar to MP4 with the difference being the lack of a video/subtitle track in the file.
File extension .opus
Category Audio file formats
Developed by Xiph.Org Foundation
Mime type audio/ogg

Format description

OPUS files contain audio in the lossy Opus format. It was developed for online streaming and supports variable bitrates. Similarly to MP3, which is also lossy, OPUS files do not contain an exact copy of the original audio recording. This is done to take up less space.

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 or it as well. Good job to the owners/writers! And, sincere 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.
