MP4 to MPG Conversion FAQ
What does the MP4 to MPG converter do?
+
Converting modern MP4 into MPG is useful for older editing software or legacy playback hardware. The converter remuxes or re-encodes as needed; expect a larger file because legacy codecs compress less efficiently.
Will resolution and frame rate be preserved in the MPG?
+
Yes. MP4 → MPG keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Is the MP4 to MPG conversion reversible?
+
You can convert the MPG back to MP4 on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
Will the converted MPG be a different size than the MP4?
+
Modern codecs compress better, so MPG from a legacy MP4 is typically 30-60% smaller at equivalent quality. Conversions in the opposite direction can grow the file.
What happens to the subtitle tracks in my MP4 file?
+
They cannot stay selectable, because MPG has no soft-subtitle stream to hold them. There are two ways out: burn them into the video during conversion, which makes them permanent and unstyleable, or export them as a separate .srt alongside the MPG for the player to load. The converter tells you which it did rather than dropping them silently. MPG inherits every MPEG-2 limitation — heavy bitrate, interlacing, no soft subtitles — plus the confusion of two extensions for one format.
Can the MPG hold more than one audio track?
+
Yes, and it is a real upgrade over MP4. MPG treats every audio stream as a first-class track, so an original-language mix, a dub and a director commentary can live in one file with the player switching between them on demand. MPG is the extension DVD authoring software, older camcorders and broadcast ingest tools recognise, so it stays useful for those pipelines.
Can I still embed the file on a web page after converting MP4 to MPG?
+
Not directly. MP4 plays inline in every browser; MPG does not, so a page embedding it falls back to a download link or an empty player frame. If the file is destined for a website, keep the MP4 for the web and treat the MPG as the archive or editing copy.
Why would I convert MP4 to an older format like MPG?
+
Because a lot of hardware never learned anything newer and never will. DVD players, in-car head units, camcorder playback modes, industrial displays and plenty of broadcast ingest equipment accept MPG and nothing else. The conversion is a deliberate step down in efficiency, bought in exchange for working on a device that has no other option.
Is there a file-size limit when converting MP4 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 MP4 files to MPG at once?
+
Yes. Drop or pick multiple MP4 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 MP4 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.
