WebM to VOB Conversion FAQ
Will resolution and frame rate be preserved in the VOB?
+
Yes. WEBM → 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 WEBM to VOB conversion reversible?
+
You can convert the VOB back to WEBM on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
Can the VOB hold more than one audio track?
+
Yes, and it is a real upgrade over WEBM. 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 WEBM 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. WEBM has nowhere to put that information, so the converted VOB starts with no chapters; add markers afterwards with a tool such as MKVToolNix or ffmpeg.
Can I still embed the file on a web page after converting WEBM to VOB?
+
Not directly. WEBM 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 WEBM 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 WEBM 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 there a file-size limit when converting WEBM 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 WEBM 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 WEBM 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 WEBM 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 WEBM 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.
