FLAC to WAV Converter

Convert FLAC to WAV free. Decodes to uncompressed PCM and keeps the source bit depth, so a 24-bit FLAC stays 24-bit and the audio is bit-for-bit identical.

What to expect when converting FLAC to WAV

Typical file-size change

larger, by a fully predictable amount

Example

WAV is uncompressed, so its size is arithmetic rather than a guess: 44.1 kHz 16-bit stereo is 10.09 MB per minute, 48 kHz 16-bit stereo is 10.99 MB, and 48 kHz 24-bit stereo is 16.48 MB. Measured here, dense material grew 2.1x and a sparse recording grew 5.4x — the FLAC size varies, the WAV size does not.

Quality: None. FLAC is lossless, so decoding returns the original PCM samples exactly, and the bit depth is carried over — a 24-bit FLAC is written as 24-bit WAV, not truncated to 16.

Best for: DAWs and editors that will not import FLAC, burning an audio CD, and processing tools that expect raw PCM.

Avoid when: you are only storing or moving the files — FLAC holds the identical audio in roughly half the space.

Tip: Because the conversion is lossless in both directions, you can work on the WAV and re-encode to FLAC afterwards with nothing lost. Verify it yourself with ffmpeg -i file -f md5 - on the FLAC and the WAV: the hashes match.

FLAC to WAV: decompressing lossless audio

FLAC compresses PCM audio losslessly — the decompressed output is bit-for-bit identical to the original recording. The conversion reverses FLAC's prediction filters and entropy coding to reconstruct the exact PCM sample values, then writes them as uncompressed WAV. The result is 2-3× larger than the FLAC with exactly the same audio content. This is a perfectly reversible conversion — the WAV can be re-encoded to FLAC with identical results.

Convert FLAC to WAV for DAWs and audio editors that don't natively import FLAC, for burning audio CDs (Red Book standard requires PCM), or for audio processing tools that expect uncompressed PCM input.

FLAC to WAV FAQ

Quick answers about compatibility, quality, metadata handling, and the most common reasons to convert FLAC files to WAV.

How do I convert FLAC to WAV?

Upload your FLAC audio to iFormat and click Convert. The track is decoded and re-encoded to WAV with metadata preserved. It's free, needs no account, and supports batch conversion of albums or playlists.

How to convert FLAC to WAV without losing sound quality

WAV is an uncompressed lossless audio format. Converting to a lossless target (WAV, FLAC, AIFF) preserves every detail of the original. Converting between lossy formats involves a small, usually inaudible re-encoding step. For the best result, always start from the highest-quality source file you have.

Can I convert multiple FLAC files to WAV at once?

Yes — upload an entire album or playlist of FLAC files and iFormat batch-converts them all to WAV. Metadata (title, artist, album, cover art) carries over for each track, so your library stays organised after conversion.

Why convert FLAC to WAV instead of keeping FLAC?

FLAC is a lossless compressed audio format used for archiving music at full quality with smaller size than WAV. WAV is better for editing and mastering at full quality. Convert when the destination device, app, or platform handles WAV more reliably than FLAC.

Does FLAC to WAV conversion keep track info like artist and album?

Yes — ID3 metadata such as title, artist, album, and cover art carries over automatically wherever the WAV format supports it, so your library stays organised after conversion.

What is FLAC?

FLAC is a lossless compressed audio format, typically used for archiving music at full quality with smaller size than WAV. Converting it to WAV makes the file easier to open, share, or upload where FLAC is not supported.

Is converting FLAC to WAV lossless?

Yes. FLAC is a lossless compression of PCM audio and WAV stores that PCM uncompressed, so decoding returns the original samples exactly. The bit depth comes across too — a 24-bit FLAC is written as a 24-bit WAV rather than being truncated to 16-bit, which is where some converters quietly lose eight bits per sample. You can check it: run ffmpeg -i yourfile -f md5 - against the FLAC and the WAV and the hashes match.
