MPEG to WebM Conversion FAQ
Is the MPEG to WebM converter free?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
My MPEG footage shows comb lines on movement — will that carry into the WebM?
+
Yes. MPEG content is often interlaced, because the format comes from the broadcast and DVD era, and this converter has no deinterlace option, so the combing carries into the WebM. If it matters, deinterlace the MPEG first in a desktop tool such as HandBrake or ffmpeg (the yadif filter). 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 WebM?
+
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. WebM 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. WebM is deliberately narrow: VP8 or VP9 video (AV1 more recently) with Vorbis or Opus audio, and nothing else.
My MPEG has several audio tracks — do they all survive into the WebM?
+
No. The converter keeps one audio track, the one with the most channels (normally the main mix), and drops the rest; there is no setting to pick a different one. To keep another track, remux the MPEG with that track first (VLC or ffmpeg can do this), then convert it. MPEG program streams are decoded by literally every DVD player, set-top box and broadcast chain ever built, and they tolerate bit errors gracefully. WebM is a poor fit anywhere outside a browser — video editors, phones’ native galleries and Smart TVs largely ignore it.
Will the WebM 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. WebM plays inline through the native HTML5 video element with no plugin and no external application. WebM plays natively in every modern browser with no plugin, no licence fee and no patent exposure, which makes it the default for web-embedded video.
Is it worth converting old MPEG recordings to WebM 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 WebM 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.
How big an MPEG file can I convert to WebM?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I convert many MPEG files to WebM at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Does the MPEG to WebM 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 WebM 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.
