This tool converts MKV to OGA completely free and without any functional limitations. Since it is based on the browser API, the processing speed is the fastest because all files are processed locally on your device and are not uploaded to our server.
Batch Convert MKV to OGA Online
With this convertor, you can easily convert multiple MKV files to OGA format directly in your browser — completely free. You can also customize the video resolution (width and height) during the conversion.
To access advanced settings, click the Options button in the top right corner. There, you can set the output size for your OGA files.
Additional Settings:
Video Size: Set the width and height for the output OGA file.
Encoding Speed:Controls how fast the video is encoded. Faster speeds may result in larger file sizes.
Video Bitrate:Set between 1–10,000 Kbps to control the video quality and file size.
Frame Rate:Defines the video’s FPS (frames per second). Higher frame rates produce larger files.
Audio Bitrate:Recommended range is 16–320 Kbps.
Cut Video: Trim the video using a start and end time in HH:MM:SS format.
For example, setting 00:00:05 to 00:00:08 will cut a 3-second clip from the video or animation.
Before converting, you can choose a folder on your device where the converted OGA files will be saved. Each MKV file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.
Save All: Once all MKV files are converted, click
Save All to instantly save all OGA files to your selected folder.
About MKV files
MKV (Matroska Video) is a flexible, open-source multimedia container that stores video, audio, subtitles, and metadata in a single file. It supports advanced features like multiple audio tracks, chapters, and modern video codecs such as H.265/HEVC. Widely used for HD movies, TV shows, and streaming, MKV is compatible with players like VLC. We can also convert MKV files to animated formats such as GIF, WebP, and APNG.
About OGA files
OGA (Ogg Audio) is an open-source audio format based on the Vorbis codec, part of the Ogg multimedia container. It provides high-quality sound at small file sizes, making it ideal for streaming and web audio. OGA is widely supported in Linux systems and open-source software, though less common on proprietary platforms. Licensed under the BSD license, it allows unrestricted use, making it a favorite for developers and content creators who prioritize freedom and quality.
