WAV to FLAC Converter – Free Online

How to Convert WAV to FLAC Online

Upload your WAV file

Drag and drop your .wav file onto the page or click to browse. You can select several WAV files at once to batch-convert them.

FLAC is preselected

The output format is already set to FLAC, so you can convert immediately. If you need to, adjust the audio codec, bitrate or sample rate in the settings panel first.

Convert and download

Click Convert. The FLAC file is processed on your own device; nothing is uploaded to a server. When it finishes, click Download to save it (or Download all to get a batch as a ZIP).

Why Convert WAV to FLAC?

FLAC delivers bit-perfect audio at roughly 50 to 60% of WAV's size, and it supports tags and album art that WAV lacks. Converting WAV to FLAC is the standard way to archive recordings, masters and CD rips while saving space.

Decoding a FLAC gives back the exact original WAV samples, so the conversion is completely reversible. Batch-convert a whole session by dropping all files at once.

Private by design: your WAV file is converted on your own device and never uploaded.
FLAC preselected: the output format is already chosen, so it is a one-click conversion.
Batch friendly: convert several WAV files in one go and download them as a ZIP.
No limits, no watermark: free for files of any size, with nothing stamped on the output.

WAV vs FLAC

WAV (Waveform Audio File Format): WAV stores uncompressed PCM audio exactly as it was recorded. It is the standard for audio editing, mastering and archiving, at the cost of large files (about 10 MB per minute of CD-quality stereo). It is best for editing, mastering, DAWs and archiving.

FLAC (Free Lossless Audio Codec): FLAC (Free Lossless Audio Codec) compresses audio to roughly half the size of WAV without discarding a single bit, so it decodes back to the identical original. It is best for lossless music libraries and audiophile listening.

In short: keep WAV when the priority is editing, mastering, DAWs and archiving, and switch to FLAC when the file is headed for lossless music libraries and audiophile listening. Need a different target? The full Audio Converter supports every format listed below.

WAV to FLAC FAQ

Is WAV to FLAC truly lossless?

Yes. FLAC is a lossless codec; decoding it reproduces the original PCM samples bit for bit.

Does FLAC support high-resolution audio?

Yes. FLAC handles 24-bit depth and sample rates well above 96 kHz, so high-resolution masters convert without change.

Is this WAV to FLAC converter free?

Yes. Converting WAV to FLAC on MediaConverter.io is completely free, with no watermark, no sign-up and no daily conversion limit.

Are my WAV files uploaded to a server?

No. The converter runs inside your browser using WebAssembly and WebCodecs, so your .wav file is read and converted on your own device. Nothing is uploaded, which keeps private recordings private and means there is no waiting in an upload queue.

Is there a file size limit for WAV to FLAC?

No fixed limit. Because processing happens locally, the practical limit is your computer's memory and patience; multi-gigabyte WAV files convert fine on a desktop browser. Very large files take longer on phones.

Will converting WAV to FLAC reduce quality?

FLAC is a lossless format, so it stores exactly the audio decoded from your WAV file. No additional quality is lost during the conversion.

Which browsers support the WAV to FLAC converter?

Current versions of Chrome, Edge, Firefox and Safari on desktop all work. Chrome and Edge are fastest because they expose hardware-accelerated WebCodecs decoders.
