Convert FLV to MP3.
Pull the soundtrack out of an old Flash Video file as an MP3 that plays on any device today.
Save the sound from old downloads
Many old web videos, lectures and music clips were saved as FLV. Extracting the audio gives you something you can actually play.
Quality
FLV soundtracks are usually MP3 or AAC already, often at modest bitrates. The 128 kbps MP3 keeps them sounding the same for everyday listening.
Size change
At 128 kbps the MP3 takes about 1 MB a minute.

Common questions
Is it free?+
Yes. Convert FLV to MP3 free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Your file is uploaded to a private bucket, converted on our own engine, and auto-deleted after 1 hour. It is never sent to a third-party converter.
Why can't I play my FLV?+
Flash Video was built for the Flash player, which browsers removed in 2020. ffmpeg still reads the files, so the sound can be saved as an MP3.
Is the video kept?+
No. Only the audio goes into the MP3. To keep the picture, use FLV to MP4.
