About MKV to MP4
MKV can contain multiple tracks and attachments. This converter writes the first video stream and, when present, its first audio stream into an MP4 container for a simpler playback copy.
Common questions
Does MKV to MP4 preserve every track and subtitle?
No. This tool selects the first video stream and the first audio stream when present. It does not include every language track, subtitle, attachment or metadata field in the source container.
Will MKV to MP4 improve the original video?
No. Transcoding can improve compatibility, but it cannot restore detail that was absent from the recording. Compare playback, sound and file size before choosing the new copy.
Does MKV to MP4 upload my selected file?
No. The selected file is processed in your browser rather than uploaded to a conversion server. The page may download processing software or models, and ordinary website connection requests still occur.
Why can the first use take longer?
The browser may first download a processing engine. Speed depends on your browser, available memory and the file's complexity. Keep this tab open until the result is ready.
