MTS to WMV Converter
Processing entirely on your device — large files may take a moment.
MTS is the raw AVCHD clip format Sony/Canon camcorders write — high-bitrate H.264 transport streams straight off the memory card. WMV barely plays outside Windows, so converting to MP4 makes these files usable again.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the MTS format
MTS is what actually comes off a Sony or Canon AVCHD camcorder's memory card: high-bitrate H.264 transport streams with AC-3/PCM audio, often split across a BDMV folder structure. The video inside is excellent — the container is what edit software refuses to import.
Converting MTS to MP4 remuxes or re-encodes into a container every device opens. Stream-copy is possible when the H.264 profile is baseline-compatible; otherwise a light re-encode fixes compatibility without visible loss.
+ Strengths
- ✓Native camcorder quality (24-28 Mbps)
- ✓Audio in AC-3/PCM survives remux
- ✓ffmpeg handles the transport stream natively
! Limitations
- −AVCHD H.264 profiles not always stream-copyable
- −Interlaced variants need deinterlacing
- −60p modes confuse older editors
About the WMV format
WMV (Windows Media Video) is Microsoft's codec family, most commonly WMV3/VC-1 inside an ASF container. In its Silverlight-era heyday it delivered good quality at dial-up-to-DSL bitrates and DRM for Windows Media services. Today it survives mainly in corporate archives, old training videos and PowerPoint embeds from the 2000s.
Non-Windows playback was always its weakness and remains so: macOS and Linux need workarounds, phones and web platforms ignore it. Converting WMV to MP4 is the standard exit, and usually saves space at the same time.
+ Strengths
- ✓Good quality-per-bit for its era
- ✓Native Windows Media integration
! Limitations
- −Poor non-Windows and mobile support
- −Obsolete next to H.264
- −DRM variants are device-locked

Frequently asked questions
Is this MTS to WMV converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MTS to WMV?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does converting MTS to WMV re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
