What does the WMV to VOB converter do?
+
It transcodes a WMV video into the VOB container. Resolution, frame rate, and aspect ratio are preserved by default — useful when you need a different format for a target player without quality loss.
Will resolution and frame rate be preserved in the VOB?
+
Yes. WMV → VOB keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Will the WMV play smoothly on modern devices after converting to VOB?
+
Yes. Legacy WMV files often fail to play in modern browsers and on iOS / Android. VOB uses widely supported codecs that play natively on phones, tablets, smart TVs, and every modern browser.
Will the converted VOB be a different size than the WMV?
+
Modern codecs compress better, so VOB from a legacy WMV is typically 30-60% smaller at equivalent quality. Conversions in the opposite direction can grow the file.
Is there a file-size limit when converting WMV to VOB?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several WMV files to VOB at once?
+
Yes. Drop or pick multiple WMV files in one upload — the converter processes them in parallel and returns a ZIP of the VOB results. There is no need to repeat the upload step per file.
What happens to my WMV files after the conversion?
+
Uploaded files and VOB outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
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 WMV 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 WMV to VOB?
+
No. WMV to VOB conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.
Is there an API for WMV to VOB conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. WMV to VOB is one of the supported pairs.
What if my WMV fails to convert to VOB?
+
Failures are usually caused by corrupted source files or unsupported WMV 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.
