TS to MP4 Converter

What happens when you convert TS to MP4

• If the video inside the TS is already H.264, the tool first copies the streams straight into the MP4. That takes seconds and loses nothing.
• If a copy is not possible, it re-encodes to H.264 video with AAC audio, which is slow in a browser: expect several times the video's length for HD footage, less at lower resolutions.

How to convert TS to MP4 online

1. Press "Choose TS files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
2. Adjust the settings if you need to: resolution and quality control the size of the result. The defaults suit most people.
3. Press "Convert to MP4". The first audio or video conversion downloads the converter engine, about 32 MB, which your browser then keeps for next time.
4. Save each MP4 with its download button. Close the tab and every trace of the files is gone from memory.

Why convert TS to MP4?

TS files usually come from TV recordings, IPTV streams and HLS video segments. People convert them to MP4 because MP4 with H.264 plays on every phone, laptop, smart TV and website, and it is what YouTube, Instagram, TikTok and WhatsApp expect.

In short, TS is good at what it was made for, and MP4 is the more practical choice when the file has to play, upload or edit somewhere else. TS does not play in most browsers directly; plays in VLC, while MP4 plays in every browser, phone and smart TV.

How to convert TS to MP4 on Windows, Mac, iPhone and Android

On Windows

Open this page in Chrome, Edge or Firefox, drag your TS files in from File Explorer, and press Convert. Each MP4 is saved to your Downloads folder. If you prefer a desktop program, VLC can also convert TS to MP4: choose Media, then Convert / Save.

On a Mac

Safari, Chrome and Firefox all work. Drag the TS files from Finder onto the drop zone and the MP4 files land in Downloads.

On iPhone and iPad

Open the page in Safari and tap Choose TS files. You can pick from Photos or from the Files app. The converted MP4 appears in Files, in the Downloads folder; to put it in your photo library, open it there, tap Share and choose Save Video.

On Android

Open the page in Chrome, tap Choose TS files and pick them from Files or your gallery. The MP4 is saved to the Download folder, where any file manager can find it. Keep the screen on while a long video converts, because Android may pause a tab in the background.

Best settings for TS to MP4

Leave Resolution on Keep original and Quality on Standard if the video only needs to change container: that is what lets the tool copy the H.264 stream straight into the MP4, which is fast and loses nothing.

If the file is too big, change either setting and the video is re-encoded with H.264. Quality uses the CRF scale: High is 20, Standard 23 and Smaller file 28. As a rule of thumb each step of about 6 on that scale halves or doubles the size. Dropping from 1080p to 720p usually saves more than lowering the quality, and it also makes the conversion much faster.

TS vs MP4: the differences

About TS and MP4 files

What is a TS file?

TS was designed for broadcast, where signal can drop at any moment, so it repeats headers constantly. That makes it robust but larger than MP4, and moving the same streams into MP4 usually needs no re-encoding.

What is an MP4 file?

MP4 is the most widely supported video format, and H.264 video with AAC audio inside it plays on essentially every device made in the last fifteen years.

TS to MP4 not working? Common problems

• The conversion is slow. Audio and container changes take seconds, but re-encoding video runs on your own processor. Lower the resolution to 720p, close other tabs, and keep the device plugged in.
• The tab stops or reloads on a very large file. Browsers limit how much memory one tab can use, around 2 GB and less on phones. Split long recordings or convert them on a computer.
• The MP4 will not play on an old device. Try the other formats offered for TS, or choose 720p, which older players handle more reliably.

Convert TS to MP4 with ffmpeg

This converter runs ffmpeg inside your browser. If you would rather use the ffmpeg command line on your own computer, this command produces an equivalent MP4 with the same kind of settings:

ffmpeg -i input.ts -c:v libx264 -crf 23 -preset veryfast -c:a aac -b:a 128k -movflags +faststart output.mp4

Replace input.ts with the name of your file. For a whole folder of TS files, run the command in a loop, or drop them all on the converter above, which processes them one after another.
