Convert TS to WAV
Short answer
Drop your TS file into the converter below and download the WAV file. It runs in your browser with FFmpeg, for files up to 100 MB; nothing is uploaded. Only the sound is kept: the video track is dropped and the audio is saved as 16-bit PCM audio in WAV.
Maximum file size: 100 MB. The first conversion loads a ~30 MB converter engine, once per visit. Nothing is uploaded - conversion runs on your device.

Key takeaways
- The 9.16 MB TS file became a 1.93 MB WAV file (-79.0%), about 1536 kbps for the 10 second clip.
- The result holds: Audio: pcm_s16le 48000 Hz 2 ch.
- In your browser the same conversion of a 3 second clip took 0.09 seconds on the single-thread engine; natively, the 10 second clip took 0.15 seconds.
- Next to it: TS to AAC (-98.2%), TS to GIF (+571%), TS to M4A (-98.2%).
Measured: TS to WAV
The converter's own ffmpeg arguments, run on a 10 second 1920 × 1080 excerpt of Big Buck Bunny (an animated film, not camera footage) saved in TS. The browser column is the same arguments on the single-thread WebAssembly core with a 3 second excerpt, in a headless run; your device will differ. Results describe this clip and these encoders.
| Check | Result |
|---|---|
| Mode | Audio re-encoded |
| Input | TS, 9.16 MB |
| Output | WAV, 1.93 MB (-79.0%) |
| Output streams | Audio: pcm_s16le 48000 Hz 2 ch |
| Time, native, 10 s clip | 0.15 s |
| Time, browser engine, 3 s clip | 0.09 s |
A re-encode decodes and encodes every frame or sample, so the time grows with the length of the file.
TS vs WAV
| TS | WAV | |
|---|---|---|
| Full name | MPEG transport stream | Waveform Audio File Format |
| What is inside | H.264 or MPEG-2 video with AAC or AC-3 audio | Uncompressed PCM audio |
| Compression | Depends on the codec inside | Uncompressed |
| Best for | Broadcast recordings, camcorders and HLS stream segments | Editing and mastering, where every sample matters; very large files |

Planning a bigger file
These are estimates scaled up from the 10 second clip. Real files differ with content, resolution and bitrate, so treat them as an order of magnitude, not a promise.
| Length of the video or recording | Input size (like ours) | WAV size | Time in your browser |
|---|---|---|---|
| 1 minute | 54.79 MB | 11.52 MB | 2 seconds |
| 10 minutes | 547.85 MB | 115.20 MB | 17 seconds |
| 1 hour | 3287.11 MB | 691.23 MB | 1.7 minutes |
A TS file of this kind reaches the 100 MB limit of the converter after about 1.9 minutes; converting it would take roughly 3 seconds on the single-thread engine, and the WAV would be about 22.05 MB.

Choosing WAV
WAV: Waveform Audio File Format. Editing and mastering, where every sample matters; very large files. TS: MPEG transport stream. Broadcast recordings, camcorders and HLS stream segments.
- Keep your original: a re-encode is a copy of a copy.
- If the destination states the format it accepts, use that and nothing else.
