MKV to VOB Conversion FAQ
What does the MKV to VOB converter do?
+
Converting modern MKV into VOB is useful for older editing software or legacy playback hardware. The converter remuxes or re-encodes as needed; expect a larger file because legacy codecs compress less efficiently.
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.
Will the converted VOB be a different size than the MKV?
+
Modern codecs compress better, so VOB from a legacy MKV is typically 30-60% smaller at equivalent quality. Conversions in the opposite direction can grow the file.
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?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several MKV files to VOB at once?
+
Yes. Drop or pick multiple MKV files in one upload — the converter processes them in parallel and returns a ZIP of the VOB results. There is no need to repeat the upload step per file.
What happens to my MKV files after the conversion?
+
Uploaded files and VOB outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
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?
+
No. MKV to VOB conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.
