About the formats
FLV
Flash Video
FLV was the format of web video in the Flash Player era. Flash ended in 2020, so today these files usually need converting before they will play.
MP3
MPEG-1 Audio Layer III
MP3 is the most widespread audio format in the world. Lossy compression shrinks files to about a tenth of WAV, and it plays on every device.
Frequently asked questions
Is converting FLV to MP3 free?
Yes, completely free. No account, no daily limit, no watermark and no queue.
Will the sound quality drop?
The soundtrack is re-encoded to MP3. At 192 kbps and above most listeners cannot tell it from the original.
Does it work on a phone?
Yes. It works on iPhone, iPad and Android, with no app to install.
Is there a file size limit?
There is no size limit set by us. Files of hundreds of MB convert too; very large files take longer and are handled more comfortably on a computer than on a phone.
