FLV to MPEG Converter
Processing entirely on your device — large files may take a moment.
Flash Video and MPEG Program Stream exist for different jobs: FLV is the Flash-era video container from thousands of old video sites and screen recordings. Modern players have dropped it. Convert .mpeg files exactly like .mpg — to MP4, MKV or modern codecs.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How FLV compares to MPEG
| FLV | MPEG | |
|---|---|---|
| Compression | VP6 / H.264 legacy | MPEG-1 / MPEG-2 |
| Quality | Of its era | Standard definition |
| Compatibility | Legacy players only | Universal decode |
| Best for | Early web video archives | Legacy disc and capture video |

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
About the MPEG format
MPG (MPEG program stream) usually means MPEG-1 or MPEG-2 video — the codecs of VCD, SVCD and DVD, and of countless home video captures in the 1990s and 2000s. MPEG-1 tops out around VHS-grade 352×288; MPEG-2 delivers proper standard definition and still runs inside broadcast and DVD infrastructure.
Playback compatibility is its superpower: MPEG-1/2 decode paths exist in every player and hardware made this century. Quality-to-bitrate efficiency, however, is a generation behind H.264 — converting old MPG files to MP4 typically halves their size.
+Strengths
- ✓Decodes on essentially every player and device
- ✓Simple, battle-tested standard
!Limitations
- −Inefficient codecs by modern standards
- −MPEG-1 is VHS-grade at best
Why convert FLV to MPEG?
There is a concrete reason this conversion exists: Dead ecosystem — Flash ended in 2020 MPEG sidesteps that — Decodes on essentially every player and device If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this FLV to MPEG 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 FLV to MPEG?
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 FLV to MPEG 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 MPEG, staying in sync with the video. If your FLV file has multiple audio tracks, the first one is used.
