Why convert FLV to WAV?

FLV was built for the Flash player, which browsers dropped for good at the end of 2020. Any FLV you still have is an archive file that needs converting before it can be watched or edited.

The practical problem: No browser has played Flash video since 2020, so FLV is effectively unplayable on the web. Editors and phones will not open it. The old codecs inside look soft next to a modern H.264 encode.

WAV solves that. Lossless, so repeated edits and exports never compound compression artefacts. The format audio editors, DAWs and mastering tools expect.

FAQ

FLV to WAV questions

Is the FLV to WAV converter free?

Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the WAV itself beyond the free-plan badge.

Do I need to install any software?

No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android. Nothing to install at either end. Where FLV plays: Desktop players only, with effort. Where the WAV you get back plays: Every desktop and audio tool; large for phones.

Does converting FLV to WAV reduce the quality?

The audio track is decoded from the FLV and written as WAV. WAV is lossless, so this step adds no further loss. The picture is discarded entirely, which is why the file gets so much smaller.

How large a file can I convert?

Anything under 1GB per upload, which is more footage in some formats than others. FLV: Moderate, heavily dated. WAV coming back: About 10 MB per minute in stereo. For anything bigger, trim or compress it first, both are free tools here.

Is my file kept private?

Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
