TS to M4V Converter
Processing entirely on your device — large files may take a moment.
MPEG Transport Stream and iTunes Video exist for different jobs: TS (Transport Stream) is the broadcast recording format used by TVs, satellite receivers and some camcorders. Converting M4V to MP4 removes the compatibility friction while keeping quality.
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 M4V format
M4V is Apple's variant of MP4, distinguished by an optional DRM layer (FairPlay) used by iTunes movie purchases, plus chapter flags. A DRM-free M4V is byte-for-byte the same beast as MP4 — rename the extension and most players never notice. Apple TV, iTunes and QuickTime treat it as first-class.
Outside Apple's world it buys you nothing: DRM-protected files are locked to authorized devices by design, and non-protected ones are just MP4. Converting M4V to MP4 is only meaningful to drop the extension or to strip DRM you are entitled to remove in your own jurisdiction — DRM-locked store purchases remain locked.
+ Strengths
- ✓Native to iTunes/Apple TV/QuickTime
- ✓Chapters and metadata for video series
- ✓DRM-free files equal MP4 in every way
! Limitations
- −Store purchases are DRM-locked to Apple devices
- −Redundant with MP4 outside Apple ecosystems
Why convert TS to M4V?
Converting makes sense where the strengths of M4V meet what TS cannot give you. Native to iTunes/Apple TV/QuickTime 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 M4V 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 M4V?
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 M4V 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.
