WMV to VOB Conversion FAQ
How do I convert a WMV file to VOB?
+
Upload your WMV file using the picker above and the converter detects the source type and runs the WMV → VOB pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
Can I add selectable subtitles once the file is VOB?
+
Yes. WMV has no usable soft-subtitle track, so subtitles for WMV content had to be burned into the picture or shipped as a separate sidecar file. VOB carries subtitles as their own selectable stream, so after conversion you can attach an SRT track the viewer can switch on, switch off or restyle. A VOB holds MPEG-2 video, AC-3 or PCM audio, and DVD subpicture subtitle streams, split into 1 GB segments by the DVD spec.
Can the VOB hold more than one audio track?
+
Yes, and it is a real upgrade over WMV. 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 WMV 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. WMV 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.
Why does my WMV file fail to convert to VOB?
+
Almost always DRM. Some WMV 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. WMV is effectively a dead end: macOS, iOS, Android and every browser need third-party decoders, and some WMV files carry DRM that cannot be converted at all.
Is there any point converting between two legacy formats like WMV and VOB?
+
Only if a specific piece of equipment demands the target. Both formats come from the same pre-H.264 era, so neither conversion buys efficiency, quality or future-proofing — it buys compatibility with one particular device. If the goal is to keep the footage usable long-term, convert to a current container instead of sideways. VOB is split across files, may be CSS-encrypted, and carries navigation packets that confuse general-purpose players.
Is the WMV to VOB converter free?
+
Yes — basic WMV → VOB conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big a WMV file can I convert to VOB?
+
Free accounts: up to 100 MB per WMV file. Premium: typically 1 GB per file, depending on the WMV source type. Very large files are split into chunks server-side when the VOB format allows.
Will conversion change the content of my WMV?
+
Conversion preserves all information that both WMV 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 WMV files to VOB at once?
+
Yes — drop multiple WMV 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 WMV 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 WMV 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.
