Only need the audio from an old FLV file — a song, a talk, a recording? Converting to MP3 extracts the sound as a small, universal file you can play anywhere, without needing an unplayable video format.
FLV vs MP3 at a glance
FLV is the video format that powered early YouTube and web video — Adobe Flash Player was discontinued in 2020, so FLV files no longer play in any current browser. MP3 is the universal audio format — plays on every device and app since the late 90s, smaller than WAV with near-identical quality.

FLV to MP3 — frequently asked questions
Is this FLV to MP3 converter really free?
Yes — completely free, with no sign-up, no watermarks and no daily limits.
Will I lose quality converting to MP3?
MP3 uses lossy compression, so the image is re-encoded at high quality (92%). For photos the difference is practically invisible; for text-heavy graphics or logos, a lossless format like PNG preserves sharp edges better.
Is the conversion private?
Video conversion runs on our servers with ffmpeg — your file is deleted immediately and never stored.
