About the formats

Extension opus
Category Audio file formats
Developed by Xiph.Org Foundation
Mime type audio/ogg

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.
Extension webm
Category Video file formats
Developed by Google
Mime type video/webm

Description

WebM is a relatively recent video file format for storing high-quality, highly compressed videos with very little quality loss. Because it is also royalty-free, it is frequently used on the web for HTML5 video playback. Its container is based on a Matroska (MKV) profile. It used the VP8 and VP9 technologies for video, and Vorbis and Opus for audio.

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!

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.
