TS to 7Z Converter
Processing entirely on your device — large files may take a moment.
7Z is ideal for big archives you store or share with power users; convert to ZIP when the recipient just needs to double-click. If your files are still in TS format, this page is the shortcut: TS (Transport Stream) is the broadcast recording format used by TVs, satellite receivers and some camcorders.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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 7Z format
7Z is the native format of Igor Pavlov's 7-Zip (1999), built around LZMA/LZMA2 compression — for years the ratio king against ZIP and RAR — with AES-256 encryption, solid archiving (similar files compress as one stream) and open, unpatented specifications. A 7Z of the same photos or code is routinely 20–40% smaller than its ZIP.
The trade-off is platform defaults: Windows Explorer and macOS Archive Utility do not open 7Z without third-party tools (7-Zip, PeaZip, Keka). It is the format for maximizing compression on your own terms, and for encrypted archives done properly (header encryption included).
+Strengths
- ✓Top-tier compression ratio (LZMA2)
- ✓Real AES-256 encryption, optional header encryption
- ✓Open format, free tooling everywhere
!Limitations
- −No native OS support — recipients need tools
- −Solid mode makes single-file extraction costly
Why convert TS to 7Z?
Converting makes sense where the strengths of 7Z meet what TS cannot give you. Top-tier compression ratio (LZMA2) Meanwhile No web or social platform support One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this TS to 7Z 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 7Z?
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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of 7Z, staying in sync with the video. If your TS file has multiple audio tracks, the first one is used.
Does converting TS to 7Z 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.
