FLV to WMV Conversion FAQ
Will resolution and frame rate be preserved in the WMV?
+
Yes. FLV → WMV keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Is there any point converting between two legacy formats like FLV 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. No current browser, phone or TV can play FLV — anything still in this container has to be moved out of it to remain watchable. 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 a file-size limit when converting FLV 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 FLV 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 FLV 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 FLV 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.
Do I need an account to convert FLV to WMV?
+
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.
Is there an API for FLV to WMV conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. FLV to WMV is one of the supported pairs.
What if my FLV fails to convert to WMV?
+
Failures are usually caused by corrupted source files or unsupported FLV 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.
