Why would broadcast need old FLV content?

Historical or archival content originally in FLV may need to be broadcast or streamed using modern infrastructure that requires TS format.

Will the low FLV quality be an issue for broadcast?

FLV content is typically low resolution. For broadcast use, the content may appear lower quality than standard broadcast material, but the conversion provides the correct container format.

What codec does the TS output use?

The converter transcodes FLV video to H.264 within the Transport Stream container, which is the standard for modern broadcast and streaming.

Can I use the TS for HLS streaming?

Yes. TS is the native container for HLS segments. The converted file can be segmented for adaptive streaming delivery.

Does this handle FLV with H.264 internally?

Yes. FLV files with H.264 can be remuxed to TS efficiently since both containers support the same codec.

FLV to TS Converter

If you have Flash Video content that needs to enter a broadcast or streaming workflow, converting FLV to Transport Stream provides the necessary container format. TS is required for broadcast playout, HLS streaming, and IPTV delivery where Flash Video is not accepted.

Convert TS to FLV instead

FLV content is transcoded to H.264 within the Transport Stream container. If the FLV already contains H.264, this can be done as a lossless remux. Legacy FLV codecs are transcoded to H.264, faithfully preserving the original quality level.

How to Convert FLV to TS

1
Upload your FLV 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.

About Our FLV to TS Converter

This converter uses FFmpeg compiled to WebAssembly (WASM) to transform your FLV 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 FLV 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.
