Quick answer: To convert TS to WEBM, add the TS file to the iHateFiles TS to WEBM converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. An open, royalty-free format that browsers play natively.
Should you convert TS to WEBM?
Do this when something specifically needs WEBM. The picture is re-encoded, so it costs a little quality; if all you need is a file that plays everywhere, MP4 is usually the better target.
The picture is re-encoded
A TS usually holds H.264 or MPEG-2 broadcast video, from a set-top box, camcorder (as .mts) or stream. This writes VP8 video with Vorbis sound into the WEBM. Both sides are compressed with loss, so this is a second generation: leave the quality at its default or higher, because the encoder is working from TS artefacts rather than the original.
Extra tracks may not survive
A TS can carry several audio tracks. WEBM is more limited, so this conversion keeps the main video and the first audio track. If you need the subtitles, save them first with Extract Subtitles.
Watch for interlacing
TS video from a DVD, camcorder or broadcast is often interlaced, which shows up in the WEBM as comb-like tearing on anything that moves. Restore Old Video removes it and can write the WEBM in the same pass.
Where the WEBM will play
WEBM plays on every modern browser and Android, but not QuickTime or older iPhones.

What usually goes wrong
About the TS. TS files from a recorder often contain several programmes or several audio tracks at once, so a converter may pick a different one than you expected.
About the WEBM. A browser screen recording is usually a WEBM with a broken duration, so players show it as zero seconds or refuse to seek. Converting it to MP4 rewrites the header and fixes the seeking.
How to convert TS to WEBM
- Add your TS file. It is read from your disk and stays there.
- Check the settings. The output format is already set to WEBM.
- Press convert and the WEBM file is saved back to your device.
Questions
How do I convert TS to WEBM?
Open this page, add your TS file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this TS to WEBM converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to WEBM lose quality?
WEBM is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several TS files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
