MPEG to MP4 Conversion FAQ
How do I convert an MPEG file to MP4?
+
Upload your MPEG file using the picker above and the converter detects the source type and runs the MPEG → MP4 pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
My MPEG footage shows comb lines on movement — will that carry into the MP4?
+
It will unless you deinterlace, and MPEG content very often is interlaced because the format comes from the broadcast and DVD era. Interlaced frames store two half-height fields captured a fiftieth of a second apart; on a progressive-scan phone or monitor that reads as horizontal combing on anything that moves. Turn on the deinterlace option and the encoder weaves the fields into whole progressive frames before writing the MP4. MPEG here means an MPEG-1 or MPEG-2 program stream, the format standardised for Video CD and then for DVD and broadcast television.
Can I add selectable subtitles once the file is MP4?
+
Yes. MPEG has no usable soft-subtitle track, so subtitles for MPEG content had to be burned into the picture or shipped as a separate sidecar file. MP4 carries subtitles as their own selectable stream, so after conversion you can attach an SRT track the viewer can switch on, switch off or restyle. Almost every MP4 in the wild is H.264 video with AAC audio; the container also legally holds HEVC, AV1 and VP9.
My MPEG has several audio tracks — do they all survive into the MP4?
+
Not dependably. MPEG stores multiple audio streams as first-class tracks, but MP4 playback support past the first track is inconsistent, so most players will only ever expose one. Choose the track you actually want before converting; the others are better extracted to their own files than left in a container that hides them. MPEG program streams are decoded by literally every DVD player, set-top box and broadcast chain ever built, and they tolerate bit errors gracefully. MP4 only supports one widely-honoured subtitle format (mov_text), and multi-track audio is unreliable outside desktop players.
Will the MP4 play in a browser when the MPEG would not?
+
Yes, and that is usually the whole reason for the conversion. An MPEG embedded in a web page either shows a broken player or forces a download, because browsers ship no decoder for it. MP4 plays inline through the native HTML5 video element with no plugin and no external application. MP4 is the safest possible delivery target — every phone, browser, console, editor and Smart TV built in the last decade plays it without extra software.
Is it worth converting old MPEG recordings to MP4 at all?
+
For anything you intend to keep, yes. MPEG belongs to an earlier generation of video tooling and the software that reads it is steadily disappearing from phones, browsers and operating systems. Moving the footage to MP4 now, while a clean decoder still exists, is the difference between an archive you can open in ten years and one you cannot. MPEG-2 needs roughly four to six times the bitrate of H.264 for the same picture, and its content is frequently interlaced, which looks combed on modern displays.
Is the MPEG to MP4 converter free?
+
Yes — basic MPEG → MP4 conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big an MPEG file can I convert to MP4?
+
Free accounts: up to 100 MB per MPEG file. Premium: typically 1 GB per file, depending on the MPEG source type. Very large files are split into chunks server-side when the MP4 format allows.
Will conversion change the content of my MPEG?
+
Conversion preserves all information that both MPEG and MP4 can represent. Format-specific features that the MP4 format doesn't support (e.g. vector data in raster output, formulas in plain-text output) are rasterized or stripped — see the format-specific notes on the result page.
Can I convert many MPEG files to MP4 at once?
+
Yes — drop multiple MPEG files into the upload zone and they are queued in parallel. Premium has more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
Does the MPEG to MP4 converter work on phones and tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end.
Which browsers does the MPEG to MP4 converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers work.
