Quick answer: To convert AVI to TS, add the AVI file to the iHateFiles AVI to TS converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Re-encodes the picture and sound into a TS container.
Should you convert AVI to TS?
Do this when something specifically needs TS. The picture is re-encoded, so it costs a little quality; if all you need is a file that plays everywhere, MP4 is usually the better target.
The picture is re-encoded
An AVI usually holds Xvid, DivX or older codecs with MP3 sound. This writes H.264 video with AAC sound in a transport stream into the TS. Both sides are compressed with loss, so this is a second generation: leave the quality at its default or higher, because the encoder is working from AVI artefacts rather than the original.
Expect a smaller TS
H.264 video is a much more efficient codec than what an AVI holds, so at the same visual quality the TS is usually a third to a half of the size.
Where the TS will play
TS plays on VLC, smart TVs and set-top boxes.

What usually goes wrong
About the AVI. Audio drifting out of sync partway through an AVI is common, because the container assumes a fixed frame rate that the source did not actually have. Re-encoding to MP4 corrects the timing.
About the TS. TS files from a recorder often contain several programmes or several audio tracks at once, so a converter may pick a different one than you expected.
How to convert AVI to TS
- Add your AVI file. It is read from your disk and stays there.
- Check the settings. The output format is already set to TS.
- Press convert and the TS file is saved back to your device.
Questions
How do I convert AVI to TS?
Open this page, add your AVI file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this AVI to TS converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to TS lose quality?
TS is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several AVI files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
