MPG to VOB Conversion FAQ
How do I convert an MPG file to VOB?
+
Upload your MPG file using the picker above and the converter detects the source type and runs the MPG → VOB pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
Can MPG be converted to VOB without re-encoding the video?
+
Yes, and it is the fast path. MPG and VOB share the same underlying box structure, so the video and audio streams are copied across byte-for-byte and only the container wrapper is rewritten. Nothing is decoded and nothing is re-compressed, so a feature-length file finishes in under a minute instead of half an hour, with output quality identical to the source. MPG is the same MPEG program stream as .mpeg — the three-letter extension is a DOS-era truncation, not a different format. VOB is the Video Object container found in the VIDEO_TS folder of every DVD — an MPEG-2 program stream with DVD-specific navigation data added.
Can I add selectable subtitles once the file is VOB?
+
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. VOB 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. A VOB holds MPEG-2 video, AC-3 or PCM audio, and DVD subpicture subtitle streams, split into 1 GB segments by the DVD spec.
Does VOB support chapter markers that MPG did not?
+
It does. VOB 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 VOB. VOB preserves the whole DVD payload — multiple angles, multiple audio languages and subtitle tracks all survive inside it.
Is there any point converting between two legacy formats like MPG and VOB?
+
Only if a specific piece of equipment demands the target. Both formats come from the same pre-H.264 era, so neither conversion buys efficiency, quality or future-proofing — it buys compatibility with one particular device. If the goal is to keep the footage usable long-term, convert to a current container instead of sideways. MPG inherits every MPEG-2 limitation — heavy bitrate, interlacing, no soft subtitles — plus the confusion of two extensions for one format. VOB is split across files, may be CSS-encrypted, and carries navigation packets that confuse general-purpose players.
Is the MPG to VOB converter free?
+
Yes — basic MPG → VOB 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 VOB?
+
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 VOB format allows.
Will conversion change the content of my MPG?
+
Conversion preserves all information that both MPG and VOB can represent. Format-specific features that the VOB 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 VOB 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 VOB 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 VOB 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.
Are my MPG files kept private?
+
Yes — uploaded MPG files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. See /privacy/ for the data-retention window.
