This tool converts OGV to MKV 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 OGV to MKV Online
With this convertor, you can easily convert multiple OGV files to MKV 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 MKV files.
Additional Settings:
Video Size: Set the width and height for the output MKV 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 MKV files will be saved. Each OGV file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.
Save All: Once all OGV files are converted, click
Save All to instantly save all MKV files to your selected folder.
About OGV files
OGV (Ogg Video) is an open-source video format based on the Theora codec, part of the Ogg multimedia container. It is commonly used for web videos, especially where royalty-free codecs are preferred, such as in Mozilla Firefox and other open-source projects. OGV supports high-quality video with efficient compression and is widely supported by HTML5-compatible browsers. It is often used for free and open-content videos, offering an alternative to proprietary formats like MP4 or H.264.
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.
