Why Convert FLV to MP3?
FLV was the standard video format during the Adobe Flash era, now largely obsolete since Flash Player was discontinued — but the audio content inside old FLV files can still be worth extracting on its own.
MP3 is the universal audio format, letting you keep and play just the sound from an old FLV file without needing any Flash-related software, which is no longer available on modern systems anyway.
This conversion is common for recovering music, lectures, or narration from archived FLV files that predate the shift to MP4-based web video.

Frequently Asked Questions
Will the audio quality be as good as the original?
The extracted MP3 reflects the quality of the audio track already embedded in your FLV file — conversion doesn't add or remove quality beyond what was originally encoded.
Can I still play FLV files directly in a browser?
No — Adobe Flash Player was discontinued and modern browsers no longer support it, which is exactly why extracting the audio (or converting the video separately) is often the only practical way to access old FLV content.
Will this work on any FLV file?
Yes, as long as the source file has an audio track — standard FLV files from the Flash era convert reliably.
Do I need Flash Player or any special software installed?
No — the conversion happens entirely on our servers, and Flash Player isn't needed or used at any point.
Is there a file size limit?
50MB free, 100MB for registered accounts.
