How do I convert WMV to MKV in a few steps?

Upload your WMV file to LetsConvert, select MKV as the output format, choose a conversion mode (Stream Copy for lossless remux if your WMV uses VC-1 or VP8, or Transcode for max compatibility), then click Convert. Download your new MKV with the same resolution, frame rate, and—unless re-encoding—identical audio/video streams.

Why convert WMV to MKV instead of keeping the original WMV?

WMV files are tied to the old ASF container and Windows Media screen—many 2024 smart TVs and media players (VLC, Roku, Kodi) refuse to read them. MKV is an open Matroska container that plays anywhere, supports embedded subtitles, multiple audio tracks, and can carry modern codecs like H.265/AV1 for up to 50% file-size savings at similar quality.

What happens to audio bitrate and video data when converting WMV to MKV?

In Stream Copy mode, LetsConvert remuxes the WMV streams into an MKV wrapper without re-encoding—video and audio stay bit-perfect, preserving VC-1/MP3 or WMA data, resolution, frame rate, and color metadata. In Transcode mode, we re-encode to a chosen codec (e.g., H.264/H.265), which can lose generational quality unless you set a high bitrate; color profiles and DPI are carried over when the target container supports them. Subtitle and chapter cues are preserved in both modes.
