Add your TS file
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.
Pulling the soundtrack out of a .ts video into .mp3 audio keeps what you can hear and drops the picture entirely. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Pulling the soundtrack out of a .ts video into .mp3 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.
An .mp3 file stores audio compressed with MPEG Audio Layer III, the codec that made digital music portable. By discarding sounds the human ear masks anyway, .mp3 shrinks a CD track to roughly a tenth of its original size, a trade-off that reshaped the entire music industry. For this route the practical draw is plays on effectively every device made in the last twenty years and small files with respectable quality at 192 kbps and above — balanced against artifacts such as pre-echo on sharp transients become audible at low bitrates, which is worth knowing before you commit a large batch.
The usual reason to take .mp3 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 plays on effectively every device made in the last twenty years, which is exactly what you want for sharing music when the recipient's device is unknown.
| Aspect | MPEG transport stream (.ts) | MP3 audio (.mp3) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Lossy — discards detail it judges invisible to shrink files |
| How it stores data | fixed 188-byte packets with sync bytes and continuity counters allow receivers to detect and skip corrupted data | lossy perceptual coding built on a hybrid filterbank and psychoacoustic masking model |
| Strongest at | saving recordings from DVRs and set-top boxes | sharing music when the recipient's device is unknown |
| Weak spot | packet overhead runs several percent above an equivalent MP4 | artifacts such as pre-echo on sharp transients become audible at low bitrates |
| Metadata | broadcast service tables (SDT/EIT) can carry channel names and program-guide data, but there is no field for user tagging | iD3v1 and ID3v2 tags carry title, artist, album, artwork, lyrics, and chapter frames; ID3v2.4 is the current revision |

Select .mp3 in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if MP3 is selectable, the route is real and validated.
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid MP3 file. Outputs keep the original filename with the .mp3 extension.
Since ts is container-oriented and mp3 is lossy-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .mp3 itself requires.
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.
Every browser, operating system, phone, car stereo, and smart speaker of the modern era plays .mp3, making it the single safest audio format to hand to a stranger. Only antique hardware with narrow bitrate support ever struggles.
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.
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.
