TS Converter Free & Private
The broadcast and streaming transport format. Convert MPEG Transport Stream files entirely in your browser — no upload, no account.
About MPEG Transport Stream
MPEG Transport Stream (.ts) is a container format designed for broadcasting and streaming, where data loss is expected. It wraps video and audio into fixed-size 188-byte packets with built-in error correction, making it resilient to transmission errors. TS is the format behind digital TV (DVB, ATSC), Blu-ray discs, and HLS (HTTP Live Streaming) — Apple's adaptive streaming protocol.

Why privacy matters for file conversion
Most online converters upload your files to remote servers where they may be scanned, stored, or shared. This tool is different — the conversion runs in your browser via WebAssembly or the WebCodecs API. Your files stay on your device. Always.

Frequently asked questions
TS is designed for streaming and broadcast — it's resilient to data loss but has higher overhead. MP4 is designed for file storage — smaller files, richer metadata, and broader device support. Convert TS to MP4 for local playback.
HLS splits video into small TS segments because TS packets can be played independently — the player doesn't need the entire file. Modern HLS also supports fragmented MP4 (fMP4) segments.
Yes, completely free with no file limits. The conversion engine runs directly in your browser — we have zero server costs for processing, so we can offer it at no charge.
Your file never leaves your device. The conversion engine runs 100% in your browser using WebAssembly or the WebCodecs API. We have no access to your files — no uploads, no logs, no data collection whatsoever.
On desktop browsers (Chrome, Firefox, Edge) files up to 500 MB convert reliably. On Safari (macOS) the practical limit is around 200 MB. On iPhone and iPad, keep files under 50 MB — iOS enforces tight memory limits for browser-based processing.
On your first visit, the browser downloads the conversion engine (24–50 MB depending on which backend is used). This is cached locally, so subsequent conversions load much faster.
Chrome, Edge, and Brave use hardware-accelerated WebCodecs when the format is supported — this is 5–10× faster than software encoding. For unsupported formats the tool falls back to ffmpeg.wasm, where Firefox typically performs best.
