Convert FLV to WMA
Updated Jul 2026
FLV is an old Flash video format that bundles picture and sound together; WMA is an audio-only format built for Windows. Converting FLV to WMA pulls out just the sound and re-encodes it, dropping the video entirely. You can do this on your own computer without uploading the file anywhere.

How to convert FLV to WMA
- Open Morphjet and drag in the FLV file, or a whole folder of them, to start.
- Choose WMA as the output. Since WMA is audio-only, Morphjet extracts the sound and leaves the picture behind.
- Convert. The WMA files are written next to your originals, and nothing leaves your machine.
FLV vs WMA: what actually changes
| FLV | WMA | |
|---|---|---|
| Contains video | Yes, picture and sound together | No, audio only |
| File size | Larger, holds video plus audio | Much smaller, sound only |
| Quality | Lossy, older Flash-era compression | Lossy, but fine for voice and casual music listening |
| Compatibility | Poor, Flash is discontinued and rarely supported anymore | Good on Windows, more limited on Mac and phones |
| Playback use | Needs a video player | Plays like any normal audio track |
When to convert, and when not to
Convert FLV to WMA when all you actually want is the sound from an old Flash video, like a lecture, interview, or webinar recording, and you don't need the picture.
Keep the FLV if you still need the video itself, since converting to WMA throws the picture away for good.
Why not just use an online converter?
Old FLV files often hold recordings people never expected to leave their own computer, like a recorded call, a home video, or a downloaded lecture. Running that file through an online converter means the audio, and everything said on it, gets uploaded to a server you don't control before you get anything back. Converting on your own machine keeps the recording, and what's in it, right where it started.
Questions
Does converting FLV to WMA lose quality?
A little, on top of whatever compression was already in the FLV's audio track. WMA is lossy too, so you're re-encoding an already-compressed file, but for voice recordings and casual listening the difference is hard to notice.
Will I still have the video after converting?
No. Extracting audio to WMA gives you a sound-only file. If you want to keep the picture too, hold onto the original FLV or convert it to a video format separately.
Can WMA files play on a Mac or iPhone?
Not natively in most cases. WMA was built for Windows, so Mac and iOS often need an extra app to open it, though Windows PCs handle it without trouble.
Why would an FLV file need converting at all?
Flash Video was the standard for web video until browsers dropped support for Flash, so old FLV files, like downloaded lecture recordings or archived clips, need converting to something modern players can actually open.
Can I convert FLV to WMA without uploading it anywhere?
Yes. Morphjet extracts the audio and converts it on your own computer, so the file never has to leave your machine or touch someone else's server.
Morphjet converts FLV, WMA, and 1,800+ other formats, all on your machine. Launching this July.
