How to convert WMV to FLAC
Add your WMV videos
Drop WMV 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 WMV 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.
WMV to FLAC: what to expect
WMV does not play on Macs, phones or in browsers without extra software. FLAC keeps full quality at about half the size of WAV. WMV is at home in legacy Windows playback; 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 WMV 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.
WMV 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 WMV 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 WMV to FLAC reduce quality?
The soundtrack is re-encoded as FLAC. FLAC itself adds no loss.
Can I convert several WMV 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 WMV 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 WMV file, press Convert and save the FLAC. There is nothing to install.
Is there a file size limit?
Yes. WMV 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.
