Add your WEBM file
Drop one or more .webm 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.
WEBM to TS
Pulling the soundtrack out of a .webm video into .ts audio keeps what you can hear and drops the picture entirely. Free, private, and validated — the file never leaves your browser.

Pulling the soundtrack out of a .webm video into .ts audio keeps what you can hear and drops the picture entirely. A .webm file is an open, royalty-free video container built specifically for the web. It restricts itself to free codecs, VP8, VP9, or AV1 for video with Vorbis or Opus for audio, so any browser can play a .webm without patent licensing concerns.
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. For this route the practical draw is corruption costs a fraction of a second, not the whole file and trivially concatenable without remuxing — balanced against packet overhead runs several percent above an equivalent MP4, which is worth knowing before you commit a large batch.
Why convert WEBM to TS?
The usual reason to take .ts audio out of a .webm 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, older iPhones and legacy Safari versions cannot play it; on the target side, the payoff is corruption costs a fraction of a second, not the whole file, which is exactly what you want for saving recordings from DVRs and set-top boxes.
WEBM vs TS at a glance
| Aspect | WebM video (.webm) | MPEG transport stream (.ts) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | structured as a deliberately restricted subset of Matroska's EBML layout | fixed 188-byte packets with sync bytes and continuity counters allow receivers to detect and skip corrupted data |
| Strongest at | serving HTML5 video without codec license fees | saving recordings from DVRs and set-top boxes |
| Weak spot | older iPhones and legacy Safari versions cannot play it | packet overhead runs several percent above an equivalent MP4 |
| Metadata | only a minimal set of Matroska tags such as title and language is defined for WebM; the spec deliberately omits attachments and rich tagging | broadcast service tables (SDT/EIT) can carry channel names and program-guide data, but there is no field for user tagging |
Pick TS as the output
Select .ts in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TS 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 TS file. Outputs keep the original filename with the .ts extension.
WEBM to TS questions, answered
Will converting WEBM to TS lose quality?
Since webm is container-oriented and ts is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .ts itself requires.
Is it private to convert WEBM files here?
Yes — the .webm 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 TS file work?
VLC, ffmpeg, and every broadcast tool read .ts natively, and smart TVs often play recordings made by their own tuners. Browsers only consume transport streams indirectly through JavaScript HLS players, so standalone .ts files need conversion for the web.
Will the TS file be bigger or smaller than my WEBM?
Much smaller — the video stream is usually 80–95% of a .webm 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 WEBM 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, only a minimal set of Matroska tags such as title and language is defined for WebM; the spec deliberately omits attachments and rich tagging; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert TS back to WEBM?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .webm → .ts → .webm is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
