WHY CONVERT
Why convert FLV to MPG
02
Broader cross-platform support
MPG is accepted by a wider range of video players, mobile devices, and streaming platforms than FLV. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
Lower storage and bandwidth cost
MPG files are typically smaller than their FLV counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.

— FAQ
Frequently asked.
Is FLV to MPG conversion free?
Yes. LocalConvert is completely free, with no signup and no per-file or per-day limits.
Do my files get uploaded anywhere?
No. FLV to MPG conversion happens entirely inside your browser using WebAssembly — your file never leaves your device.
What's the maximum file size?
There's no fixed cap — the practical limit is your device's available memory. Very large files may take longer or fail on low-RAM devices.
Does it work offline?
Yes — once the page has loaded, FLV to MPG conversion works without an internet connection. Re-open the page once to cache it.
Will conversion preserve quality?
LocalConvert uses the industry-standard tools (FFmpeg, ImageMagick, Pandoc) — quality matches what professionals use on the command line. Lossy formats will still lose some quality on each re-encode.
