TS to ASF Converter
Processing entirely on your device — large files may take a moment.
Converting ASF to MP4 unlocks old corporate and training videos on modern devices. 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.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

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 ASF format
ASF (Advanced Systems Format) is Microsoft's streaming container from the Windows Media era. WMV video and WMA audio live inside it, often with DRM in its commercial life. It carries the same 188-packet-ish streaming DNA as other late-90s containers, plus Microsoft-specific metadata and marker tracks.
Outside Windows it is effectively unreadable without special tools. The exit strategy is MP4: video re-encodes to H.264, audio to AAC, and the file joins the modern world. ASF files carrying DRM-protected streams remain locked — only unprotected content converts.
+ Strengths
- ✓Native Windows Media streaming container
- ✓Holds WMV/WMA with rich metadata
! Limitations
- −Non-Windows support is poor
- −DRM-protected files are locked

Frequently asked questions
Is this TS to ASF 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 ASF?
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.
Does converting TS to ASF 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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of ASF, staying in sync with the video. If your TS file has multiple audio tracks, the first one is used.
