Is this FLAC to WAV converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple FLAC files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

What bitrate will the converted audio use?

We default to 192 kbps for MP3, 128 kbps for OGG/Opus, and 320 kbps for M4A/AAC. These settings are perceptually transparent — most listeners can't tell the difference in a blind test.

Will my metadata (ID3 tags, album art) be preserved?

Yes, when both formats support it. Tags carry over on conversions like MP3→M4A or FLAC→MP3. WAV has limited tag support, so some metadata may not transfer.

Is there any quality difference between FLAC and WAV?

No — both are lossless formats. FLAC is compressed lossless (smaller files), WAV is uncompressed (larger files). Decoding FLAC to WAV is a perfectly lossless conversion; the audio data is identical.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert FLAC to WAV?

FLAC is a compressed lossless format and is excellent for storing music archives efficiently, but its compression can create compatibility issues in professional audio workflows. Digital audio workstations including Pro Tools, older versions of Logic Pro, and some hardware samplers from Roland and Akai do not support FLAC import natively. When you need to drag an audio file directly into a DAW session or load it onto a hardware device, WAV is the safest choice because it has been supported universally since the format was introduced in 1991.

WAV is the native audio format for Windows and the baseline format that virtually all professional audio software reads without any conversion step. Avid Pro Tools sessions, Ableton Live sets, hardware samplers like the Akai MPC series, and audio editing software like Sound Forge all treat WAV as the primary working format. When collaborating with engineers who use different setups, providing WAV stems eliminates the risk of format incompatibility entirely.

Converting FLAC to WAV is a lossless operation. Because both formats store audio in an uncompressed or lossless state, the conversion preserves every bit of the original audio data exactly. The output WAV file will be larger than the FLAC source because WAV does not use compression, but the audio quality is identical. Sample rate, bit depth, and channel layout all carry over without modification. If the FLAC file is 24-bit 96 kHz stereo, the output WAV will be 24-bit 96 kHz stereo with no rounding or resampling.

Quality & file size: FLAC to WAV

Typical file sizes: FLAC 20–40 MB → WAV 30–50 MB.

Both FLAC and WAV use lossy compression. We transcode at high quality settings (equivalent to WAV's recommended web quality) to minimize generational loss.

Color depth: FLAC supports standard color, WAV supports standard color.

Transparency: FLAC does not support transparency. WAV does not support transparency — transparent areas become solid white.

Your FLAC files are converted 100% inside your browser. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
