M4V to VOB Conversion FAQ
Will resolution and frame rate be preserved in the VOB?
+
Yes. M4V → 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 M4V to VOB conversion reversible?
+
You can convert the VOB back to M4V on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
Why does my M4V file fail to convert to VOB?
+
Almost always DRM. Some M4V files are encrypted at the bitstream level by the store or software that issued them, and an encrypted stream cannot be decoded by us or by anything else without the licence key. Files you recorded, exported or downloaded unprotected convert normally; a licensed purchase will not, and no converter can honestly promise otherwise. DRM-protected M4V purchases cannot be converted by anything; only unprotected M4V files are convertible, and non-Apple players often need the extension renamed.
Why would I convert M4V 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 M4V 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 M4V 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 M4V 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 M4V 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 M4V 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 M4V to VOB conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. M4V to VOB is one of the supported pairs.
What if my M4V fails to convert to VOB?
+
Failures are usually caused by corrupted source files or unsupported M4V 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.
