FLAC to WAV Converter

How to Convert FLAC to WAV Online

1. Upload Your FLAC Files: Drag and drop FLAC files or click "+ Add Files" to select them from your device. Batch uploads are supported — drop a whole album at once.
2. Pick Audio Sample Rate and Channel: Default is "Original" — keep this for a bit-perfect, lossless decode of the FLAC. To match a target system, change Audio Sample Rate (8000, 12000, 16000, 24000, 44100, or 48000 Hz) and Audio Channel (Mono or Stereo). 44.1 kHz stereo is the CD-audio standard; 48 kHz stereo is the standard for video editing.
3. Trim (Optional): Open Trim to set a start time and duration in hours/minutes/seconds/milliseconds — useful when you only need a clip from a long live recording or DJ set.
4. Convert and Download: Click "Convert" and download each WAV individually or grab the whole batch as a ZIP. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert FLAC to WAV?

FLAC and WAV are both lossless audio formats — converting between them is bit-perfect, meaning the WAV file decodes the exact same audio samples that were originally encoded into the FLAC. The only thing you "lose" is compression: FLAC squeezes audio down to roughly 50-70% of the original PCM size, while WAV stores raw uncompressed PCM. Reasons people make this trip every day:

• DAW and editing software compatibility — Pro Tools, Logic Pro, Ableton Live, and Adobe Audition all import WAV without question. FLAC support is improving, but older sessions, plugins, and shared studio setups still expect PCM-in-RIFF.
• CD burning and physical media — Audio CDs are mastered from 16-bit / 44.1 kHz stereo PCM. Most burning apps (iTunes/Music, Windows Media Player, Nero) require WAV or AIFF input, not FLAC.
• Hardware playback without a FLAC decoder — older car stereos, DJ controllers (some Pioneer CDJ firmware before CDJ-3000), and embedded devices read WAV reliably even when FLAC fails.
• Sample libraries and game audio — Unity, Unreal Engine, FMOD, and Wwise commonly ingest WAV; many sample-pack publishers ship WAV because every sampler understands it.
• Loudness mastering and analysis tools — many offline meters, dithering plugins, and broadcast-loudness checkers operate directly on WAV/AIFF PCM rather than decoding FLAC on the fly.
• Archival of CD rips before re-encoding — rip CD to FLAC for storage, decode to WAV when you need to re-encode to a lossy format (MP3, AAC, Opus) using a fresh codec pass.

FLAC vs WAV vs ALAC — Lossless Format Comparison

WAV File Size by Bit Depth and Sample Rate (per minute, stereo)

A typical 4-minute CD-quality FLAC track lands around 20-25 MB; the equivalent 16-bit / 44.1 kHz stereo WAV is ~40 MB. The 4 GiB WAV file-size cap (a 32-bit unsigned integer in the RIFF header) translates to roughly 6.5 hours of CD-quality stereo or 3 hours of 24-bit / 96 kHz stereo in a single file.

Frequently Asked Questions

Is FLAC to WAV conversion truly lossless?

Yes. FLAC decodes to the exact PCM samples that were encoded — a byte-by-byte hash of the decoded audio matches what went in. The resulting WAV is identical in audio data to the source; the only differences are container format (RIFF vs FLAC stream) and the absence of compression.

Why is my WAV roughly twice the size of the FLAC?

FLAC applies lossless compression — typically reducing PCM audio to 50-70% of its raw size by predicting samples and entropy-coding the residual. WAV stores raw PCM with zero compression, so a FLAC that's 20 MB usually expands to about 35-45 MB as WAV. Sample rate and bit depth are unchanged; you're paying in bytes for universal compatibility.

What sample rate and bit depth should I pick?

If you're not sure, leave Audio Sample Rate on "Original" — that decodes the FLAC at its native rate (most often 44.1 kHz for CD rips, 48 kHz for video sources, 96 kHz for hi-res downloads). Choose 44.1 kHz for CD burning, 48 kHz for video and broadcast work, and 96 kHz only if your source is already hi-res and your downstream tools need it. The bit depth of the output WAV matches the FLAC's source bit depth (commonly 16-bit signed little-endian PCM).

Can I edit the converted WAV in Audacity?

Yes. Audacity, Pro Tools, Logic Pro, Ableton Live, Reaper, GarageBand, FL Studio, and Adobe Audition all import 16-bit and 24-bit PCM WAV without plugins or codecs. Audacity also handles FLAC directly via libsndfile, but exporting to WAV is the safer common denominator when sharing project files with other engineers.

Will the WAV play on my old car stereo or DJ controller?

In most cases, yes — WAV PCM has been a universal playback format since 1991. If the device's USB media list shows ".wav" support and the firmware accepts 16-bit / 44.1 kHz stereo, your converted file will play. Hi-res sources (24-bit, 96 kHz+) may not work on legacy hardware; in that case, downsample to 16-bit / 44.1 kHz when converting.

What about album metadata, cover art, and track tags?

FLAC stores metadata as Vorbis Comments plus embedded artwork; WAV's tagging support (LIST INFO chunks and ID3) is limited and not consistently read by every player. If you rely on artist/album/track tags, expect them to be sparse or missing after conversion. For a tag-friendly lossless target on Apple devices, convert to ALAC (M4A) instead — FLAC to AIFF is another lossless option with somewhat better tag support than WAV.

Why would I do the reverse — convert WAV back to FLAC?

To shrink files by 30-50% with zero quality loss for long-term archival or transfer over slow connections. After editing a WAV in your DAW, re-encoding to FLAC for distribution is a standard final step — see WAV to FLAC for that direction.

Is there a file size or count limit?

Files run on our servers, so the practical cap is upload size and connection speed on our servers-side quota. A WAV file itself is capped at 4 GiB by the format's 32-bit header, which is roughly 6.5 hours of CD-quality stereo or about 3 hours of 24-bit / 96 kHz stereo. For longer recordings, split into multiple files or convert to a format without the 4 GiB ceiling (FLAC, ALAC, or RF64/W64 variants).

Can I trim a specific section while converting?

Yes — expand the Trim option and set a start point and duration in hours/minutes/seconds/milliseconds. The trimmed region is decoded losslessly to WAV; you don't need a separate editing step for simple cuts. For more complex multi-cut work, use the dedicated Audio Cutter tool.

What if I want a smaller lossy file instead of WAV?

If you don't need lossless quality (sharing over messaging apps, embedding in slideshows, podcast distribution), encode to MP3 or AAC instead. FLAC to MP3 is the most common choice — a 320 kbps MP3 is roughly a quarter of the WAV's size and transparent for most listening.
