Convert MKV to AVI Online

About MKV (source)

MKV (Matroska) is an open, highly flexible container built for archival and home theater use. It supports multiple video, audio, and subtitle tracks in one file, plus chapters and attachments. MKV is common for Blu-ray rips, anime fansubs, and Plex/Kodi libraries.

Where MKV shows up:

• Blu-ray and DVD rips with commentary and multiple languages
• Anime and foreign films with soft subtitles
• Plex, Jellyfin, and Kodi media servers
• Preserving multiple audio tracks without splitting files

About AVI (target)

AVI (Audio Video Interleave) is a legacy Microsoft container from the 1990s. It appears in old camcorder exports, downloaded videos, and industrial capture systems. AVI often contains DivX, Xvid, or uncompressed video with MP3 or PCM audio.

Where AVI is used:

• Legacy security DVR and industrial camera exports
• Old downloads and camcorder archives
• Software that never added MP4 support
• Embedded systems with AVI-only playback

Converting MKV to AVI

Pros

• Runs on legacy AVI-only software and hardware

Cons

• Obsolete for modern sharing and streaming
• Poor subtitle and multi-track support

Caveats

• AVI is legacy output. Expect MPEG-4 Part 2 or Xvid-style video unless you choose H.264 in settings. Multi-track audio and modern subtitles are poorly supported in AVI.
• Muxara maps the primary video and audio streams. Extra subtitle or audio tracks may not carry over unless you choose subtitle handling in the converter settings.
• Uploads are processed on dedicated workers and deleted within 24 hours. For offline batch work, use the free Muxara Mac app.
