FLV
Flash video
FLV was the format behind web video in the Flash era. Flash Player was retired at the end of 2020, so FLV files no longer play in any browser.

How to convert FLV to MP3
Add your FLV videos
Drop FLV files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
MP3 is already chosen
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab and can take a while for large files.
Download
Save the MP3, or download everything as one ZIP if you converted several files.
Why ToAny
Private by construction
The FLV to MP3 converter is part of this page and runs inside your browser. Your videos are never sent to ToAny or to anyone else.
No upload, no queue
Nothing has to travel to a server and back, so work starts the moment you press Convert. How long it takes depends on your device and the size of the file.
Free, without an account
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
FLV to MP3: what to expect
FLV no longer plays in any browser now that Flash is gone. MP3 plays on every phone, computer, car stereo and speaker. FLV is at home in nothing new; it survives in old downloads and stream recordings; MP3 is the usual choice for music and podcasts that must play anywhere. The MP3 contains the soundtrack only; the picture is dropped.
The defaults suit most files. Under Options you can choose the bitrate and trim the start and end. This is demanding work for a browser: a long or high-resolution file can take several minutes, and your device does all of it, so keep the tab open.
This pair uses the compatibility engine, ffmpeg built for the browser, because FLV is not handled by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB. MP3 is written at 192 kbps unless you choose another bitrate.
FLV vs MP3
MP3
MP3 audio
MP3 is the audio format everything plays. It shrinks audio to roughly a tenth of its uncompressed size by discarding sound most listeners cannot hear. Newer codecs are more efficient, but nothing matches its compatibility.

Questions
Are my videos uploaded anywhere?
No. The FLV to MP3 conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Does converting FLV to MP3 reduce quality?
The soundtrack is re-encoded as MP3. MP3 is lossy, but at a normal bitrate the difference is hard to hear. You can choose the bitrate under Options.
Can I convert several FLV files at once?
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
How do I convert FLV to MP3 on Windows, Mac, iPhone or Android?
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the FLV file, press Convert and save the MP3. There is nothing to install.
Is there a file size limit?
Yes. FLV to MP3 runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
