Why would I need a TS file?

TS is required for broadcast television playout, HLS live streaming, Blu-ray authoring, and IPTV delivery. It is designed for reliable transmission over unreliable networks with built-in error correction.

Is the conversion from MP4 to TS lossless?

If the MP4 contains H.264 video with AAC audio, the conversion to TS is a lossless remux since Transport Stream natively supports these codecs.

Can I use the TS file for HLS streaming?

Yes. HLS (HTTP Live Streaming) uses TS segments as its underlying transport format. The converted file can be segmented for HLS delivery.

Will the TS file be larger than the MP4?

Slightly, due to Transport Stream overhead including error correction packets and timing information. The increase is typically small, around 1-3%.

Does TS support H.264 and H.265 video?

Yes. Transport Stream supports both H.264 and H.265, as well as MPEG-2 and other codecs commonly used in broadcast and streaming applications.

MP4 to TS Converter

MPEG Transport Stream is the standard format for broadcast television, Blu-ray discs, and HLS live streaming. Converting MP4 to TS is essential when preparing content for broadcast playout, creating HLS streaming segments, or authoring Blu-ray discs that require Transport Stream input.

100% Private — Your files never leave your device

Convert TS to MP4 instead

MP4 and TS both support H.264 and H.265 codecs. When the MP4 contains these codecs, the conversion is a lossless remux that simply repackages the streams in the Transport Stream container with added timing and error correction data.

How to Convert MP4 to TS

1
Upload your MP4 file by dragging it into the converter or clicking the upload button.
2
Select TS as the output format.
3
Click Convert and download your Transport Stream file once processing completes.

About Our MP4 to TS Converter

This converter uses FFmpeg compiled to WebAssembly (WASM) to transform your MP4 files into TS format entirely inside your web browser. When you select a file for conversion, the processing happens locally on your device. Your file is never uploaded to any server, never transmitted over the internet, and never stored anywhere outside your own computer. This privacy-first architecture makes our tool safe for confidential and sensitive content — including legal recordings, medical files, financial presentations, personal media, and any other material you would not want on a third-party server.

The conversion process works by decoding the MP4 input using FFmpeg's highly optimized decoders, then encoding the output in TS format with carefully tuned settings that balance quality and file size. When possible, the tool uses stream copy mode to remux (rewrap) compatible streams without re-encoding, which preserves the original quality with zero generational loss. When re-encoding is necessary due to codec differences between the two formats, the converter uses high-quality encoding settings to minimize any visible or audible quality reduction.

Supported input formats include MP4, MOV, AVI, MKV, and WebM for video, with automatic detection of the codecs and parameters inside your source file. The output is optimized for maximum compatibility with modern devices and platforms including Windows, macOS, Linux, iOS, Android, smart TVs, and all major web browsers.

Why browser-based conversion is safer: traditional online converters require you to upload your file to a remote server, where it is processed by third-party infrastructure and then made available for download. This workflow exposes your data to interception during upload, unauthorized access on the server, unclear data retention policies, and potential data breaches. Professionals in regulated industries such as healthcare (HIPAA), legal (attorney-client privilege), and finance (SOX, GDPR) often cannot use server-based converters without violating compliance requirements. Our WebAssembly-powered approach eliminates all of these risks by ensuring your data never leaves the browser sandbox on your own device.

The tool handles files up to 500 MB on desktop browsers and 200 MB on mobile devices. No account registration, no software installation, and no recurring subscription is required. Conversion typically completes in seconds for small files and a few minutes for larger ones, depending on your device's processing capabilities. Once the conversion is finished, you can download the result immediately and the source data is discarded from browser memory.
