M2TS to FLV Converter
Processing entirely on your device — large files may take a moment.
Blu-ray MPEG-TS Video and Flash Video exist for different jobs: M2TS is the Blu-ray and AVCHD camcorder transport stream — high-quality footage that most phones, social apps and editors refuse to open directly. Rescuing FLV recordings means converting them to MP4 before Flash compatibility disappears completely.
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 M2TS format
M2TS is the transport stream of Blu-ray discs and AVCHD camcorders: MPEG-2 or H.264 video in fixed 188-byte packets, built for broadcast-style resilience rather than compactness. Copy a camcorder's clips off its card and you are holding M2TS files; so is most of a decrypted Blu-ray folder structure.
The format plays in VLC and a handful of editors, but phones, social platforms and web apps reject it. Converting to MP4 is the standard hand-off: the video re-encodes to H.264 at your chosen quality and the result plays literally everywhere.
+ Strengths
- ✓Broadcast-grade error resilience
- ✓Native to Blu-ray and AVCHD cameras
- ✓Carries high-bitrate, high-quality footage
! Limitations
- −Rejected by phones, web players and social platforms
- −Packet overhead inflates file size
About the FLV format
FLV (Flash Video) was the video format of the early streaming web — YouTube's original delivery container from 2005 to ~2010, played by Adobe Flash Player. Later versions carried H.264/AAC, but the container lived and died with Flash, which reached end-of-life in 2020.
Modern browsers cannot play FLV at all, and only niche players (VLC) bother. If you have an FLV archive, converting to MP4 recovers the same H.264 video into a container every device accepts.
+ Strengths
- ✓Only relevant for early-web video archives
! Limitations
- −Dead ecosystem — Flash ended in 2020
- −No browser support at all

Frequently asked questions
Is this M2TS to FLV 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 M2TS to FLV?
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 M2TS to FLV 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.
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.
