Convert TS to MP4.
TS files come from TV recordings, stream captures and screen recorders. Convert them to MP4 so they play in any browser, import into any editor, and stop choking your player.
Built for broadcast, not for your hard drive
The transport-stream format was designed to survive being beamed over the air or streamed across a flaky network — it's chopped into small packets so a dropout doesn't ruin everything. Great for broadcasting, less great once it's sitting on your computer as a .ts file: scrubbing through it is jerky, and a lot of editors refuse it outright. MP4 fixes all of that.
Edit-ready captures
If you've recorded a stream or pulled a TV capture, convert to MP4 before you start editing — it drops cleanly into any timeline and seeks instantly.

Common questions
What is a TS file?+
TS (MPEG transport stream) was built for broadcasting and streaming — it's how digital TV and HLS streams carry video. That makes it robust over a network but awkward as a file: many players can't seek through it cleanly and editors stumble on it. MP4 holds the same video in a friendlier container.
Is it free?+
Yes — convert TS to MP4 free, with no signup. Paid plans add larger files and bigger batches.
Is my file private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
Will I lose quality?+
The video is usually already H.264, so converting to MP4 mostly re-wraps it — quality stays essentially identical while compatibility jumps to universal.
