About Flash Video (FLV)
Flash Video (FLV) is the container Adobe Flash Player used to stream video on the web, typically with H.264 or the older Sorenson Spark and VP6 codecs.
Videos saved from websites of the Flash era and from some older streaming and recording tools.
Adobe ended Flash Player at the end of 2020 and browsers removed it, so FLV files need a converter or a desktop player such as VLC.
Convert FLV to MP3 online free, no account required — MP3 is a universally supported lossy audio format.

Why won't my old FLV videos play anywhere anymore? Flash Player was retired at the end of 2020 and browsers dropped support, so the only practical way to keep them is converting to MP4.
About MP3
MP3 (MPEG-1 Audio Layer III) is a lossy audio format from the early 1990s. It removes the sound listeners are least likely to notice, typically at 128 to 320 kbit/s.
It plays on virtually every device and app, which makes it the default for music files, podcasts and audiobooks.
MP3 tops out at 320 kbit/s and two channels, and every re-encode removes a little more detail.
Why convert music to MP3? Every device, car stereo and app made in the last 25 years plays it, so nothing and nobody is left out.
What changes when you convert FLV to MP3
- The soundtrack of the FLV is re-encoded as MP3 at the default settings, so it is close to the original but not bit-identical.
- Only the sound is kept: the MP3 file contains the audio track of your FLV, and the picture is dropped.
