MP4 to VOB Conversion FAQ
How do I convert an MP4 file to VOB?
+
Upload your MP4 file using the picker above and the converter detects the source type and runs the MP4 → VOB pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
Can the VOB hold more than one audio track?
+
Yes, and it is a real upgrade over MP4. VOB treats every audio stream as a first-class track, so an original-language mix, a dub and a director commentary can live in one file with the player switching between them on demand. VOB preserves the whole DVD payload — multiple angles, multiple audio languages and subtitle tracks all survive inside it.
Does VOB support chapter markers that MP4 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. MP4 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.
Can I still embed the file on a web page after converting MP4 to VOB?
+
Not directly. MP4 plays inline in every browser; VOB does not, so a page embedding it falls back to a download link or an empty player frame. If the file is destined for a website, keep the MP4 for the web and treat the VOB as the archive or editing copy. VOB is split across files, may be CSS-encrypted, and carries navigation packets that confuse general-purpose players.
Why would I convert MP4 to an older format like VOB?
+
Because a lot of hardware never learned anything newer and never will. DVD players, in-car head units, camcorder playback modes, industrial displays and plenty of broadcast ingest equipment accept VOB and nothing else. The conversion is a deliberate step down in efficiency, bought in exchange for working on a device that has no other option.
Is the MP4 to VOB converter free?
+
Yes — basic MP4 → VOB conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big an MP4 file can I convert to VOB?
+
Free accounts: up to 100 MB per MP4 file. Premium: typically 1 GB per file, depending on the MP4 source type. Very large files are split into chunks server-side when the VOB format allows.
Will conversion change the content of my MP4?
+
Conversion preserves all information that both MP4 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 MP4 files to VOB at once?
+
Yes — drop multiple MP4 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 MP4 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 MP4 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 MP4 files kept private?
+
Yes — uploaded MP4 files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. See /privacy/ for the data-retention window.
