TS to WEBM Converter
Processing entirely on your device — large files may take a moment.
TS (Transport Stream) is the broadcast recording format used by TVs, satellite receivers and some camcorders. WebM delivers the best size-to-quality ratio for embedding video on websites without plugins.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the TS format
TS (MPEG Transport Stream) is the packetized format of broadcast television — DVB, ATSC, ISDB — and of AVCHD/Blu-ray camera segments. Fixed 188-byte packets make it resilient: a damaged broadcast moment corrupts one packet, not the file. That is exactly what broadcast needs and exactly why TS wastes bytes compared to MP4.
TS plays fine in VLC and other full-featured players but not in browsers or social platforms, so camera clips and recorded broadcasts end up converted to MP4 for anything beyond local viewing.
+ Strengths
- ✓Broadcast-grade resilience to transmission errors
- ✓Native format of TV capture and AVCHD cameras
! Limitations
- −No web or social platform support
- −Packet overhead inflates file size
About the WEBM format
WebM is Google's royalty-free video format for the web: a Matroska subset carrying VP8/VP9/AV1 video with Vorbis/Opus audio. YouTube serves most non-premium playback in VP9 WebM, and HTML5 `<video>` plays it natively in every modern browser — no licensing math required.
Efficiency is the selling point: VP9 and AV1 match or beat H.264/HEVC at the same quality for typical web content. Hardware decode is now widespread, though older Safari versions and some TVs remain the compatibility floor.
+ Strengths
- ✓Royalty-free codecs (VP9/AV1, Opus)
- ✓Native HTML5 video support
- ✓Efficient at web bitrates
! Limitations
- −Weaker support on older Safari/TVs
- −Not the default for camera or editor workflows

Frequently asked questions
Is this TS to WEBM converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for TS to WEBM?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does converting TS to WEBM re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
