Need Audio from Your FLV Files?

FLV (Flash Video) was the dominant web video format throughout the 2000s. If you have archived FLV files with music, interviews, or other audio content, extracting the audio track to MP3 makes it portable and easy to access.

Converting FLV to MP3 pulls the audio stream from the video container. You get just the sound-no video, smaller file size, playable on any device.

How to Convert FLV to MP3

Upload your FLV file - Select your Flash video file
Confirm MP3 output - MP3 extracts just the audio track
Download your file - Get your audio file ready for any player

The audio extraction happens in your browser-fast, private, no software needed.

Why Extract Audio from FLV?

Preserve Music from Old Web Videos

Flash is dead, but your FLV files may contain music, podcasts, or audio content worth keeping. Extracting to MP3 preserves the audio in a format that will work for decades.

Create Podcast-Style Audio

If your FLV contains interviews, lectures, or spoken content, extracting to MP3 creates audio files you can listen to on the go-in the car, at the gym, anywhere.

Save Storage Space

If you only need the audio, why keep the video? A 100MB FLV might extract to a 10MB MP3, freeing significant storage space.

Archive Before Format Obsolescence

FLV support is declining as Flash disappears from the web. Converting now ensures you won't lose access to the audio content locked in legacy video files.

Audio Quality from FLV Files

The MP3 quality depends on the source FLV's audio track:

High-quality FLV - May have 128-320kbps audio, extracts cleanly
Web-quality FLV - Often 64-96kbps audio, limited quality
Old streaming FLV - May have mono or low-bitrate audio

Our converter extracts the audio at its original quality-we can't improve what's in the source file, but we won't degrade it either.

What About Video Conversion?

Need to convert the video too? FLV can convert to modern formats:

FLV to MP4 - Modern video format for all devices
FLV to WebM - Open format for web use
FLV to MOV - Apple/QuickTime compatible

If you need just the audio, FLV to MP3 is the most efficient option.

Batch Convert Multiple FLV Files

Have a collection of old FLV files? Upload multiple files and extract audio from all of them at once. Build a music library from your video archives efficiently.

Works on Any Device

No Flash player or special software needed. Convert FLV to MP3 in any modern browser:

Windows, Mac, Linux, Chromebook
Chrome, Firefox, Safari, Edge
iPhone, iPad, Android

Pro Tip

If you have a large FLV archive, prioritize converting files with unique audio content. Music videos, interviews, and rare recordings should be extracted before the files become unplayable.

Common Mistake

Expecting CD-quality audio from web FLV files. Most were encoded at low bitrates (64-128kbps) for streaming. The extracted MP3 reflects this source quality limitation.

Best For

Extracting music, podcasts, or interviews from archived Flash video files. Perfect for creating audio-only versions of video content you want to keep.

Not Recommended

Don't bother converting if you have the original audio source available. FLV audio is often compressed for web streaming. Use original sources when possible for best quality.
