About the TS format
TS (MPEG Transport Stream) is the packetized format of broadcast television — DVB, ATSC, ISDB — and of AVCHD/Blu-ray camera segments. Fixed 188-byte packets make it resilient: a damaged broadcast moment corrupts one packet, not the file. That is exactly what broadcast needs and exactly why TS wastes bytes compared to MP4.
TS plays fine in VLC and other full-featured players but not in browsers or social platforms, so camera clips and recorded broadcasts end up converted to MP4 for anything beyond local viewing.
+ Strengths
- ✓Broadcast-grade resilience to transmission errors
- ✓Native format of TV capture and AVCHD cameras
! Limitations
- −No web or social platform support
- −Packet overhead inflates file size
About the AC3 format
AC3 (Dolby Digital) is the surround format of the DVD era and still the standard audio track on Blu-rays and broadcast TV. It carries 5.1 channels at 384–640 kbps — built to make home theatre rumble. Extracted from discs or remuxed downloads, .ac3 files are common on everyone's drive.
Phones and most editors do not decode it. The practical move is conversion: MP3 for listening, WAV when the audio is destined for editing. Both keep the mix you know — just in a format every device handles.
+ Strengths
- ✓True 5.1 surround from disc sources
- ✓The DVD/Blu-ray audio standard
! Limitations
- −Almost no mobile or web support
- −Lossy — downmixing loses the surround image

Frequently asked questions
Is this TS to AC3 converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for TS to AC3?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
Does converting TS to AC3 re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
