VOB to WMV Conversion FAQ
How do I convert a VOB file to WMV?
+
Upload your VOB file using the picker above and the converter detects the source type and runs the VOB → WMV pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
My VOB recordings are split into numbered parts — does WMV have the same limit?
+
No, and that is one of the better reasons to move. The VOB container has a practical single-file ceiling that long or high-bitrate recordings run straight into, which is exactly why old captures arrive as part1, part2, part3. WMV has no equivalent limit, so the pieces can be rejoined into one continuous file. VOB is split across files, may be CSS-encrypted, and carries navigation packets that confuse general-purpose players.
What happens to the subtitle tracks in my VOB file?
+
They cannot stay selectable, because WMV has no soft-subtitle stream to hold them. There are two ways out: burn them into the video during conversion, which makes them permanent and unstyleable, or export them as a separate .srt alongside the WMV for the player to load. The converter tells you which it did rather than dropping them silently. 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.
My VOB has several audio tracks — do they all survive into the WMV?
+
Not dependably. VOB stores multiple audio streams as first-class tracks, but WMV playback support past the first track is inconsistent, so most players will only ever expose one. Choose the track you actually want before converting; the others are better extracted to their own files than left in a container that hides them. VOB preserves the whole DVD payload — multiple angles, multiple audio languages and subtitle tracks all survive inside it.
Why does my VOB file fail to convert to WMV?
+
Almost always DRM. Some VOB 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.
Will the WMV still play smoothly on a phone or a TV?
+
It may not. VOB is decoded by dedicated silicon on phones, tablets and TVs, which is why it plays without flattening the battery. WMV typically falls back to software decoding on the same hardware — higher CPU load, a warmer device, and dropped frames on 4K material. For a device target, VOB is the safer container to stay in.
Is there any point converting between two legacy formats like VOB and WMV?
+
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.
Is the VOB to WMV converter free?
+
Yes — basic VOB → WMV conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big a VOB file can I convert to WMV?
+
Free accounts: up to 100 MB per VOB file. Premium: typically 1 GB per file, depending on the VOB source type. Very large files are split into chunks server-side when the WMV format allows.
Will conversion change the content of my VOB?
+
Conversion preserves all information that both VOB and WMV can represent. Format-specific features that the WMV 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 VOB files to WMV at once?
+
Yes — drop multiple VOB 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 VOB to WMV 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.
