Возможно ли конвертировать FLV в MP3?
Да - FLV конвертируется в MP3.

Вы можете сделать это прямо здесь с помощью нашего бесплатного конвертера - регистрация не нужна, и ваш файл будет удален сразу после завершения.

Upload the FLV to our free converter above or use FFmpeg from the command line - both produce a standard MP3 in seconds. The main caveat: if the audio inside the FLV is AAC rather than MP3, a re-encode is required, which introduces a small, usually inaudible quality loss.

Зачем конвертировать FLV в MP3?

FLV (Flash Video) packages audio and video together, but listeners often want only the soundtrack - a recorded speech, a music stream, or a podcast captured as video. Extracting the audio gives a compact .MP3 that plays on any device. Flash was retired in 2020, so converting to MP3 is also the practical way to archive audio from old FLV recordings.

Способы конвертации FLV в MP3

VLC media player FREE

Go to Media > Convert/Save, add your .flv, select the Audio - MP3 profile, set a .mp3 output path, and click Start.

FormatFactory FREE

Add the .flv, choose MP3 as the target format, and click Start - FormatFactory handles both MP3 and AAC source audio.

Command line - FFmpeg CLI

Run ffmpeg -i input.flv -vn -c:a copy output.mp3 to extract the audio; if the source track is AAC, use -c:a libmp3lame instead of -c:a copy.

Качество и на что обратить внимание

  • FLV files can contain either MP3 or AAC audio - only FFmpeg's stream-copy mode (-c:a copy) avoids re-encoding; VLC and most GUI tools always re-encode.
  • The output quality cannot exceed the source: a 64 kbps FLV will not produce a better-than-64-kbps MP3 regardless of the encoder setting.
  • The video track is discarded entirely; keep the original .flv if you may need the video later.

Часто задаваемые вопросы

Will converting FLV to MP3 lose quality?
Not if the FLV already holds an MP3 track and you use FFmpeg with -c:a copy - the output is bit-for-bit identical. A re-encode (required when source audio is AAC) adds only a small, usually inaudible loss.
How do I know what audio codec is inside my FLV?
Run ffmpeg -i input.flv without specifying an output file; FFmpeg prints stream details including whether the audio is mp3 or aac.
Can I convert multiple FLV files at once?
Yes - FFmpeg supports batch scripting, and GUI tools like FormatFactory and Freemake Video Converter include a built-in batch queue.
What if my FLV file has no sound?
If ffmpeg -i input.flv shows no audio stream, the file is video-only and there is nothing to extract as MP3.
