MPG to WebM Conversion FAQ
What does the MPG to WEBM converter do?
+
MPG is a legacy container, often poorly supported on modern devices. Converting to WEBM rewraps the video with a current codec (H.264 / H.265 / VP9) for broad browser, phone, and TV compatibility.
Will resolution and frame rate be preserved in the WEBM?
+
Yes. MPG → WEBM keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
My MPG footage shows comb lines on movement — will that carry into the WEBM?
+
Yes. MPG 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 MPG first in a desktop tool such as HandBrake or ffmpeg (the yadif filter). MPG is the same MPEG program stream as .mpeg — the three-letter extension is a DOS-era truncation, not a different format.
Can I add selectable subtitles once the file is WEBM?
+
Yes. MPG has no usable soft-subtitle track, so subtitles for MPG 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.
Is WEBM worth targeting for a video on a web page?
+
For a page you control, yes. WEBM was built for exactly that job — it plays inline in every current browser with no plugin, no licence fee and no patent exposure, which is why it became the default for embedded and background video. Away from the browser it is the weaker choice: editing software, phone galleries and televisions largely ignore it, so it is a delivery format rather than a storage one. Keep the master in something else and publish this. 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.
My MPG 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 MPG with that track first (VLC or ffmpeg can do this), then convert it. MPG is the extension DVD authoring software, older camcorders and broadcast ingest tools recognise, so it stays useful for those pipelines. 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 MPG would not?
+
Yes, and that is usually the whole reason for the conversion. An MPG 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.
Is it worth converting old MPG recordings to WEBM at all?
+
For anything you intend to keep, yes. MPG 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. MPG inherits every MPEG-2 limitation — heavy bitrate, interlacing, no soft subtitles — plus the confusion of two extensions for one format.
Is there a file-size limit when converting MPG 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 batch-convert several MPG 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.
What happens to my MPG files after the conversion?
+
Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Will my WEBM play on phones, tablets, and TVs?
+
Yes — WEBM uses modern codecs that play natively on iOS, Android, Smart TVs, game consoles, and every modern browser.
