MPG to WebM Conversion FAQ
How do I convert an MPG file to WebM?
+
Upload your MPG file using the picker above and the converter detects the source type and runs the MPG → WebM pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
My MPG footage shows comb lines on movement — will that carry into the WebM?
+
It will unless you deinterlace, and MPG 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 WebM. 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.
My MPG has several audio tracks — do they all survive into the WebM?
+
Not dependably. MPG stores multiple audio streams as first-class tracks, but WebM 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. 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. 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 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 the MPG to WebM converter free?
+
Yes — basic MPG → WebM conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big an MPG file can I convert to WebM?
+
Free accounts: up to 100 MB per MPG file. Premium: typically 1 GB per file, depending on the MPG source type. Very large files are split into chunks server-side when the WebM format allows.
Will conversion change the content of my MPG?
+
Conversion preserves all information that both MPG and WebM can represent. Format-specific features that the WebM 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 MPG files to WebM at once?
+
Yes — drop multiple MPG 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 MPG 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 MPG 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.
