Who typically has TS files?

TS files are usually made by digital TV recorders (PVRs, DVRs), set-top boxes, some camcorders, and video capture cards. They’re also common when capturing live TV streams or exporting from broadcast equipment. Most consumer devices don’t use TS for everyday video, so it’s mostly seen in TV recording and video archiving workflows.

Will the MP4 play on my phone or smart TV?

Yes, in almost all cases. MP4 with H.264 video and AAC audio is supported by iPhone, Android, iPad, smart TVs, and every major browser. The only exception would be if your TS used an unusual video codec; this tool expects H.264 or MPEG-2 video streams.

Does the conversion keep subtitles or multiple audio tracks?

No. This preset only copies the main video stream and converts a single audio track to AAC. Additional audio tracks, subtitles, or metadata in the TS are not transferred. For advanced needs, use a desktop app like ffmpeg directly and remap the streams.

Can I use built-in tools to convert TS to MP4?

Windows Photos, Clipchamp, and macOS QuickTime won’t open TS files. VLC can play TS and convert to MP4, but usually re-encodes both streams and doesn’t set faststart. HandBrake also works, but always re-encodes, so you lose some quality. Videozify keeps the video untouched for best results.

Will file size change after converting TS to MP4?

Very little. For a 4-minute HD TS file around 80 MB, the MP4 will be about the same size. If the original audio was high-bitrate AC-3, the MP4 may be a few megabytes smaller after converting to AAC. Video size stays nearly identical because there’s no re-encoding.

Is there any quality loss in the audio?

The audio is converted to AAC at 192 kbps, which is transparent for most voices and TV content. If your TS used uncompressed PCM audio, there is a small loss, but for MPEG or AC-3 sources, 192 kbps AAC is a close match for day-to-day listening. Video quality is unchanged.

Can I convert encrypted or copy-protected TS files?

No. This tool only works with standard, unprotected TS files. TV recordings with DRM or encryption will not convert. You’ll see an error if the file is protected. Only convert files you have the right to use.

What if my TS file is MPEG-2 video and not H.264?

MP4 supports both H.264 and MPEG-2 video, but not every device plays MPEG-2 in MP4. This tool copies the video stream, so if your TS is MPEG-2, the MP4 will be too. For maximum compatibility, consider re-encoding to H.264 using a desktop app if you have problems with playback.

A TS to MP4 converter takes a .ts (MPEG-2 Transport Stream) video and repackages the video stream directly into an MP4 file, converting audio to AAC for device compatibility. No video re-encoding, so there is no generational loss. The output is a standard MP4 you can play, edit, or share almost anywhere.

How to convert TS to MP4

Drag your TS file into the box above or click Browse to select it from your device.
Wait for the file to load. Confirm it’s the right video by checking the preview.
Press Convert. The video will be copied and the audio converted to AAC 192 kbps.
Download your MP4 when it appears. The file stays local—nothing is uploaded.

Why convert TS to MP4?

TS files are often created by digital TV recorders, camcorders, or exported from video capture cards. The format is designed for broadcasting and streaming, not everyday playback or editing. Many video editors, phones, and websites refuse to open TS files, or only play them with glitches or missing audio.

MP4 is the most widely supported video container in the world. Phones, tablets, smart TVs, web browsers, and editing software all expect MP4. Email attachments, WhatsApp, and most cloud drives handle MP4 but may choke on TS.

Converting from TS to MP4 with this tool copies the video stream directly—no re-encoding, so you keep the exact picture quality of the original. The audio is converted to AAC at 192 kbps because not all TS files use an audio format that MP4 supports. This is a practical balance: video remains untouched, and audio becomes compatible without a huge size increase.

A typical 4-minute TS file from a TV recording or camera, say 80 MB at 1080p, will produce an MP4 of about the same size—sometimes a few megabytes smaller if the original audio was less efficient. There’s no visible loss in video quality. The tool also adds faststart, so your MP4 plays immediately online instead of waiting to buffer.

You should not convert if your TS file already plays everywhere you need, or if you’re archiving for broadcast use. Converting to MP4 is for compatibility, not for editing MPEG-2 video or making it smaller. If you need to trim, compress, or edit, do that after conversion, or use a dedicated editor.

If you want to trim your new MP4, use the video trimmer. To compress large MP4s for sharing, try the video compressor.

TS vs MP4: what's the difference?

Property	TS	MP4
Extension	.ts	.mp4
Type	MPEG-2 Transport Stream	MPEG-4 Part 14 container
Typical size (4 min)	75–100 MB (HD TV)	75–100 MB
Compression	MPEG-2 or H.264 (varies)	Same video, AAC audio
Quality	Source picture, often broadcast	Unchanged video, AAC audio
Device support	TV, set-top boxes, some editors	Phones, browsers, editing apps

TS (Transport Stream) is a container format for broadcasting, used by TV recorders and some cameras. MP4 is the universal container for modern devices, web, and editors.

Does converting TS to MP4 reduce quality?

No, not for the video stream. This preset copies the video bit-for-bit into the MP4 container—no new compression, no loss. The only change is the audio: most TS files use MPEG audio or AC-3, which isn’t guaranteed to play in MP4. So the audio is converted to AAC at 192 kbps, which is a solid, transparent setting for typical speech or TV soundtracks.

There’s no bitrate slider because the video isn’t being re-encoded. If your original TS had multiple audio tracks, only the main one is converted. The +faststart flag is set, so your new MP4 can be streamed or played instantly online.

If you see a big size change (for example, a 100 MB TS becomes a 60 MB MP4), check the output: it could mean the audio track was much larger in the TS, or that the original had extra streams that were dropped for compatibility. The video quality itself is unchanged.

When should you NOT convert TS to MP4?

If your TS file already works in your editor, media player, or on your TV, there’s no technical reason to convert. Archivists and broadcasters often keep TS files because they may include extra metadata, subtitles, or multiple audio tracks that MP4 does not preserve.

If you need to cut commercials or edit the file, some editors (especially on Windows) can handle TS natively. For example, VLC can play TS and export to MP4, but may re-encode both streams, which takes longer and can reduce quality. Windows Photos and macOS QuickTime do not open TS files directly.

If your TS file is damaged or incomplete, converting to MP4 won’t fix playback errors. Try repairing it in a tool like VLC or a dedicated TS stream fixer first.
