Convert FLAC to WAV online

Your FLAC file is converted to WAV right here in your browser, using FFmpeg compiled to WebAssembly. Nothing is uploaded to us, the audio never leaves your device. Quality is preserved and the download is ready in seconds.

What is a FLAC file?

FLAC (Free Lossless Audio Codec) compresses audio the way ZIP compresses files: the data gets smaller (typically 50 to 60% of WAV size) but decodes back to exactly the original samples. Nothing is lost, ever.

FLAC is the archiving and audiophile standard: music collections, radio archives and oral-history projects use it to keep perfect masters at half the storage cost of WAV.

Why WAV?

WAV (Waveform Audio File Format) stores raw, uncompressed PCM audio, every sample, exactly as captured. A 44.1 kHz stereo WAV runs to roughly 10 MB per minute, which is the price of keeping everything.

Convert to WAV before editing: because nothing is compressed, you can cut, process and re-export as many times as you like without any generational quality loss. It is also the most widely accepted format for professional submission and archiving. FLAC playback support is broad but not total, iPhones handle it awkwardly, and some editors still prefer WAV, and the files remain far larger than any lossy format.

Frequently asked questions

Will converting FLAC to WAV lose quality?

Nothing is lost at all. FLAC and WAV are both lossless, so this conversion is bit-perfect. The audio that comes out is sample-for-sample identical to what went in. Convert freely in either direction.

Is it free?

Yes, completely, with no account and no watermark. The conversion runs on your own device, so it costs us nothing to let you use it. The only limit is file size: up to 50 MB, which is what a browser can hold in memory comfortably.

Do I need to install anything, or upload my file?

Neither. It runs entirely in your browser using FFmpeg compiled to WebAssembly. Your audio is never sent to us, which is also why it works on a slow connection, only the page downloads, not your file.

Need a transcript of the audio?

Autrans also transcribes audio in Nigerian English, Pidgin, Yoruba, Hausa, Igbo, French, and Spanish.
