How do I convert an MKV file to AVI using LetsConvert?

Visit LetsConvert's MKV to AVI page, upload your MKV file, and select AVI as the output. If your target device is old, enable Stream Copy mode to avoid re-encoding and keep the original H.264 video and AC3 audio. Start conversion and download the resulting AVI file.

Why should I convert MKV to AVI instead of keeping the original MKV?

MKV is a flexible container for HD video, multiple audio tracks, subtitles, and chapters, but many DVD players and legacy editors cannot open it. AVI is widely supported by older hardware and video software. Converting to AVI makes your file playable in those environments, often with a smaller metadata overhead, though AVI may not support advanced subtitles.

Does the conversion preserve video and audio quality, subtitles, and metadata?

Our converter keeps the original video resolution, frame rate, and color space. With Stream Copy, audio streams (AC3, MP3, PCM) are copied without re-encoding, so bitrate and channel map remain identical. However, MKV's soft subtitles, chapter points, and chapter names are discarded because AVI lacks those container features. If you choose re-encoding, video is recoded using standard MPEG-4 codecs, which may reduce file size at some quality cost.
