MPG to MKV Conversion FAQ
How do I convert an MPG file to MKV?
+
Upload your MPG file using the picker above and the converter detects the source type and runs the MPG → MKV 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 MKV?
+
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 MKV. 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 MKV?
+
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. MKV 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. MKV is codec-agnostic: H.264, HEVC, VP9 and AV1 video sit happily beside AAC, FLAC, Opus, DTS or Dolby audio in the same file.
Does MKV support chapter markers that MPG did not?
+
It does. MKV stores chapters as container metadata, so a long recording can be navigated by section instead of by scrubbing a progress bar. MPG has nowhere to put that information, so if the source shipped with a chapter list it was in a sidecar file — hand that to the converter and it gets written into the MKV. MKV is the archival container of choice because it stores unlimited audio tracks, soft subtitles, chapter markers and cover art in one file.
Will the MKV still play smoothly on a phone or a TV?
+
It may not. MPG is decoded by dedicated silicon on phones, tablets and TVs, which is why it plays without flattening the battery. MKV typically falls back to software decoding on the same hardware — higher CPU load, a warmer device, and dropped frames on 4K material. For a device target, MPG is the safer container to stay in. MKV has almost no native hardware support — phones, browsers and TVs usually need VLC or a remux before they will play it.
Is it worth converting old MPG recordings to MKV 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 MKV 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 MKV converter free?
+
Yes — basic MPG → MKV 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 MKV?
+
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 MKV format allows.
Will conversion change the content of my MPG?
+
Conversion preserves all information that both MPG and MKV can represent. Format-specific features that the MKV 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 MKV 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 MKV 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 MKV 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.
