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 FLAC
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.
FLAC 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 FLAC, or download everything as one ZIP if you converted several files.
Why ToAny
Private by construction
The FLV to FLAC 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 FLAC: what to expect
FLV no longer plays in any browser now that Flash is gone. FLAC keeps full quality at about half the size of WAV. FLV is at home in nothing new; it survives in old downloads and stream recordings; FLAC is the usual choice for archiving music at full quality. The FLAC contains the soundtrack only; the picture is dropped.
The defaults suit most files. Under Options you can 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.
FLV vs FLAC
FLAC
FLAC audio
FLAC compresses audio to roughly half the size of WAV without losing anything, like a ZIP for sound. It is the standard for lossless music collections. Apple's Music app is the notable holdout.
Opens in Android, Windows, VLC, most hi-fi players; Apple Music does not import it

Questions
Are my videos uploaded anywhere?
No. The FLV to FLAC 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 FLAC reduce quality?
The soundtrack is re-encoded as FLAC. FLAC itself adds no loss.
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 FLAC 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 FLAC. There is nothing to install.
Is there a file size limit?
Yes. FLV to FLAC 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.
