Drop one or more .ts files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
TS to WMV

Pulling the soundtrack out of a .ts video into .wmv audio keeps what you can hear and drops the picture entirely. A .ts file is an MPEG transport stream, the packetized format built to carry television through unreliable channels like antennas, satellites, and cable. DVR recordings, IPTV captures, and HLS streaming segments all use .ts, making it one of the most common raw broadcast formats people encounter.
A .wmv file contains Windows Media Video, Microsoft's proprietary codec family, almost always wrapped in an ASF container. The extension was everywhere on Windows XP-era PCs, from downloaded clips to Movie Maker exports, but it has faded as MP4 became universal. For this route the practical draw is excellent support across legacy Windows software and vC-1 encodes hold up reasonably well for their age — balanced against effectively abandoned by Microsoft itself, which is worth knowing before you commit a large batch.
Why convert TS to WMV?
The usual reason to take .wmv audio out of a .ts file is that only the sound matters — a talk, interview, song, or podcast segment. Keeping the video stream would waste storage, and a dedicated audio file is easier to trim, tag, and play. On the source side, packet overhead runs several percent above an equivalent MP4; on the target side, the payoff is excellent support across legacy Windows software, which is exactly what you want for playing old Movie Maker projects and family archives.
TS vs WMV at a glance
| Aspect | MPEG transport stream (.ts) | Windows Media video (.wmv) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | fixed 188-byte packets with sync bytes and continuity counters allow receivers to detect and skip corrupted data | aSF container carrying WMV1, WMV2, or WMV3 (VC-1) video, typically with WMA audio |
| Strongest at | saving recordings from DVRs and set-top boxes | playing old Movie Maker projects and family archives |
| Weak spot | packet overhead runs several percent above an equivalent MP4 | effectively abandoned by Microsoft itself |
| Metadata | broadcast service tables (SDT/EIT) can carry channel names and program-guide data, but there is no field for user tagging | aSF content-description attributes hold title, author, copyright, and rating fields, plus extended attributes used by Windows Media Player libraries |
Pick WMV as the output
Select .wmv in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if WMV is selectable, the route is real and validated.
Convert on your device
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid WMV file. Outputs keep the original filename with the .wmv extension.
TS to WMV questions, answered
Will converting TS to WMV lose quality?
Since ts is container-oriented and wmv is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .wmv itself requires.
Is it private to convert TS files here?
Yes — the .ts file is processed inside your browser tab and never uploaded. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded. Close the tab and the file is gone from memory.
Where will the WMV file work?
Windows 10 and 11 still play .wmv out of the box, but macOS dropped support after the QuickTime plugin era ended, and no browser or mobile OS will touch it. Conversion to MP4 is required for web or cross-platform use.
Will the WMV file be bigger or smaller than my TS?
Much smaller — the video stream is usually 80–95% of a .ts file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
What happens to the metadata in my TS file?
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, broadcast service tables (SDT/EIT) can carry channel names and program-guide data, but there is no field for user tagging; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert WMV back to TS?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .ts → .wmv → .ts is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
