FLAC to WAV Converter

Converting FLAC to WAV decompresses the audio back into raw PCM: exactly the same samples that encoded to the FLAC in the first place. The file gets 2–3× larger, nothing changes about the sound, but tools that insist on uncompressed input will now accept it.

What changes when you convert FLAC to WAV

Zero quality change in either direction. FLAC is lossless, so the WAV output is bit-identical to the PCM that was encoded. You gain universal DAW compatibility at the cost of disk space.

When to use this conversion

  • Loading audio into a DAW or plugin that doesn't read FLAC directly
  • Burning a music CD where red-book audio is PCM anyway
  • Feeding audio to legacy hardware samplers or embedded systems that only read WAV
  • Preparing files for mastering engineers who request WAV as a standard deliverable

Where the output plays

WAV runs on every audio device and every audio application ever made. It's the closest thing to a universal format in the audio world.

About these formats

FLAC (Free Lossless Audio Codec)

FLAC is a lossless compressor: it shrinks PCM audio to roughly 50–60% of its original size and decodes back to a bit-perfect copy. It supports tags, cue sheets, and up to 32-bit / 655 kHz, which makes it the de facto format for CD rips and audiophile music libraries.

WAV (Waveform Audio File Format)

WAV is Microsoft and IBM's uncompressed PCM container. A stereo CD-quality recording takes about 10 MB per minute. Because nothing is thrown away and nothing is compressed, WAV is the universal working format for recording, editing, and mastering in every major DAW.

How It Works

  1. Add your FLAC files Drag FLAC files onto the page, or click to pick them from your file browser. Batch uploads are fine.
  2. Choose WAV settings Pick bitrate or quality level for the WAV output. Defaults match common target use cases.
  3. Convert in your browser FFmpeg runs locally via WebAssembly. Nothing uploads. Progress shows per file so you know exactly what's happening.
  4. Download WAV files Grab each converted file individually, or download the whole batch as a single ZIP.

FAQ

Do I lose any quality converting FLAC to WAV?

No. FLAC is lossless, so the decoded WAV contains the exact same PCM samples that were encoded originally. You can verify with the MD5 checksum FLAC stores in the file header.

How much larger will the WAV be?

Typically 1.5–2× the FLAC size. FLAC usually compresses to 50–60% of the original PCM, so decompression roughly doubles the file size.

Are my files private?

Yes. The converter runs entirely in your browser using FFmpeg compiled to WebAssembly. Your audio files are never uploaded, never sent to a server, and never leave your device.

Is there a file size limit?

There's no hard limit, but because everything runs in your browser you're bounded by available memory. Files over about 2 GB total can get slow or hit browser memory limits. Process in smaller batches if you run into issues.
