MKV to VOB Conversion FAQ
Will resolution and frame rate be preserved in the VOB?
+
Yes. MKV → VOB keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Is the MKV to VOB conversion reversible?
+
You can convert the VOB back to MKV on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
My MKV files came from ripping discs — will they convert cleanly?
+
Cleanly, yes, but check what is inside first. A rip usually carries more than the picture — often several audio languages, sometimes a subtitle track or chapter marks — and whether those survive depends entirely on what the VOB can hold, not on the rip. The other thing to know is that the encode already happened: the ripper chose a bitrate years ago and no conversion can recover detail it discarded, so if the discs are still around, re-ripping beats re-encoding. MKV is Matroska, an open container designed in 2002 with no licensing restrictions and no ceiling on what it can hold.
Why would I convert MKV 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. VOB preserves the whole DVD payload — multiple angles, multiple audio languages and subtitle tracks all survive inside it.
Is there a file-size limit when converting MKV to VOB?
+
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 MKV files to VOB 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 MKV 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 VOB play on phones, tablets, and TVs?
+
VOB plays in most desktop players but is sometimes unsupported on mobile and TV. For broadest reach, consider MP4 instead.
Do I need to install software to convert MKV to VOB?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert MKV to VOB?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
Is there an API for MKV to VOB conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. MKV to VOB is one of the supported pairs.
What if my MKV fails to convert to VOB?
+
Failures are usually caused by corrupted source files or unsupported MKV variants. Re-export from the original app and try again; if it still fails, the contact page forwards the file to support so we can diagnose.
