What does the FLV to MPG converter do?
+
It transcodes a FLV video into the MPG container. Resolution, frame rate, and aspect ratio are preserved by default — useful when you need a different format for a target player without quality loss.
Will resolution and frame rate be preserved in the MPG?
+
Yes. FLV → MPG keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Will the FLV play smoothly on modern devices after converting to MPG?
+
Yes. Legacy FLV files often fail to play in modern browsers and on iOS / Android. MPG uses widely supported codecs that play natively on phones, tablets, smart TVs, and every modern browser.
Will the converted MPG be a different size than the FLV?
+
Modern codecs compress better, so MPG from a legacy FLV is typically 30-60% smaller at equivalent quality. Conversions in the opposite direction can grow the file.
Is there a file-size limit when converting FLV to MPG?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several FLV files to MPG at once?
+
Yes. Drop or pick multiple FLV files in one upload — the converter processes them in parallel and returns a ZIP of the MPG results. There is no need to repeat the upload step per file.
What happens to my FLV files after the conversion?
+
Uploaded files and MPG outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
Will my MPG play on phones, tablets, and TVs?
+
MPG plays in most desktop players but is sometimes unsupported on mobile and TV. For broadest reach, consider MP4 instead.
Do I need to install software to convert FLV to MPG?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert FLV to MPG?
+
No. FLV to MPG conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.
Is there an API for FLV to MPG conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. FLV to MPG is one of the supported pairs.
What if my FLV fails to convert to MPG?
+
Failures are usually caused by corrupted source files or unsupported FLV variants. Re-export from the original app and try again; if it still fails, the contact page forwards the file to support so we can diagnose.
