VOB to WMV Conversion FAQ
Will resolution and frame rate be preserved in the WMV?
+
Yes. VOB → WMV keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
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 are dropped. WMV has no soft-subtitle stream to hold them, and the converter neither burns them into the picture nor exports them as a separate file. If you need them, extract the subtitles to an .srt file with a desktop tool such as ffmpeg or MKVToolNix before converting, and load that file alongside the WMV in your player. 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?
+
No. The converter keeps one audio track, the one with the most channels (normally the main mix), and drops the rest; there is no setting to pick a different one. To keep another track, remux the VOB with that track first (VLC or ffmpeg can do this), then convert it. 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 there a file-size limit when converting VOB to WMV?
+
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 VOB files to WMV 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 VOB 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 WMV play on phones, tablets, and TVs?
+
WMV 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 VOB to WMV?
+
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.
