How to convert WAV to FLAC

  1. Add your WAV audio files

    Drop WAV 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.

  2. FLAC is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.

  3. Download

    Save the FLAC, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The WAV to FLAC converter is part of this page and runs inside your browser. Your audio files are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

WAV to FLAC: what to expect

WAV files are about ten times larger than an MP3 of the same recording. FLAC keeps full quality at about half the size of WAV. WAV is at home in recording, editing and mastering; FLAC is the usual choice for archiving music at full quality.

The defaults suit most files. Under Options you can trim the start and end.

The conversion uses your browser's own video and audio codecs (WebCodecs), with hardware acceleration where the device has it; the file is read from disk as it goes and can be up to 2 GB. Where the browser lacks a codec, the page falls back to the compatibility engine.

WAV vs FLAC

WAV

WAV audio

WAV stores audio as raw, uncompressed samples. Nothing is lost, which makes it the standard working format in audio editing, and files run to about 10 MB per minute at CD quality.

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 audio files uploaded anywhere?

No. The WAV 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 WAV to FLAC reduce quality?

No further quality is lost: FLAC stores the decoded audio exactly. The result is identical in content.

Can I convert several WAV 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 WAV 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 WAV file, press Convert and save the FLAC. There is nothing to install.

Is there a file size limit?

Yes. Files up to 2 GB are accepted. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
