MPG to FLV Conversion FAQ
What does the MPG to FLV converter do?
+
It transcodes a MPG video into the FLV 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 FLV?
+
Yes. MPG → FLV keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Will the MPG play smoothly on modern devices after converting to FLV?
+
Yes. Legacy MPG files often fail to play in modern browsers and on iOS / Android. FLV uses widely supported codecs that play natively on phones, tablets, smart TVs, and every modern browser.
Will the converted FLV be a different size than the MPG?
+
Modern codecs compress better, so FLV from a legacy MPG 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 MPG to FLV?
+
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 MPG files to FLV at once?
+
Yes. Drop or pick multiple MPG files in one upload — the converter processes them in parallel and returns a ZIP of the FLV results. There is no need to repeat the upload step per file.
What happens to my MPG files after the conversion?
+
Uploaded files and FLV 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 FLV play on phones, tablets, and TVs?
+
FLV 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 MPG to FLV?
+
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 MPG to FLV?
+
No. MPG to FLV 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 MPG to FLV conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. MPG to FLV is one of the supported pairs.
What if my MPG fails to convert to FLV?
+
Failures are usually caused by corrupted source files or unsupported MPG 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.
