Is there any quality loss when converting FLAC to WAV?

No. Both FLAC and WAV are lossless formats. FLAC applies lossless compression — the decoder reconstructs every audio sample exactly as it was before compression. The resulting WAV is bit-for-bit identical in audio content to the original FLAC. Converting back to FLAC from that WAV would recover an identical FLAC.

Is my FLAC file uploaded to a server?

No. This tool runs entirely in your browser using the Web Audio API. Your file is read into browser memory, decoded locally, re-encoded as WAV, and downloaded — it never leaves your device. Refreshing the page clears all data.

Which bit depth should I choose — 16-bit or 32-bit float?

16-bit PCM is the standard for CD audio and is compatible with virtually every media player, DAW, and device. Choose 16-bit unless you specifically need to preserve a higher dynamic range. 32-bit float retains the full precision of the decoded audio buffer and is useful if you plan further processing in a DAW, but the file size will be about double that of a 16-bit WAV.

Why does the WAV file size increase compared to the FLAC?

FLAC stores audio with lossless compression, typically reducing file size by 40–60% compared to raw PCM. WAV stores uncompressed PCM data, so the WAV output will always be larger than the FLAC source. A 30 MB FLAC file might produce a 50–80 MB WAV, depending on duration, sample rate, and bit depth.

What FLAC files are supported?

Any FLAC file your browser can decode via the Web Audio API — which covers standard FLAC (44.1 kHz, 48 kHz, up to 96 kHz) in stereo or mono. Very high sample-rate files (192 kHz) may not be supported in all browsers. Chrome and Firefox have the broadest FLAC support. Safari also supports FLAC as of Safari 14.

Can I convert multiple FLAC files at once?

This tool processes one file at a time. For batch conversion, the fastest approach is FFmpeg: run `for f in *.flac; do ffmpeg -i "$f" "${f%.flac}.wav"; done` in a terminal on Linux or macOS. On Windows PowerShell: `Get-ChildItem *.flac | ForEach-Object { ffmpeg -i $_.FullName ($_.BaseName + ".wav") }`.

FLAC vs. WAV — At a Glance

FLAC

Lossless compression (40–60% smaller)
Supports rich metadata tags
Not accepted by all DAWs or devices

WAV (PCM)

Universal DAW and device support
Required for CD burning (16-bit / 44.1 kHz)
Larger file size (uncompressed PCM)

WAV Bit Depth Reference

Bit Depth	Dynamic Range	Size / min (stereo 44.1 kHz)	Typical Use
16-bit	96 dB	~10.1 MB	CD audio, streaming, DAW export
24-bit	144 dB	~15.2 MB	Studio recording, mastering
32-bit float	~1,528 dB*	~20.2 MB	DAW internal processing, stems

* 32-bit float uses a floating-point representation; effective dynamic range far exceeds integer formats.

Done!

Summary

Drop a FLAC file and download a lossless WAV in seconds — everything decodes and re-encodes locally in your browser, nothing is uploaded.

How it works

Drop a FLAC file (or click to browse) onto the drop zone.
Your browser decodes the FLAC audio into raw PCM samples using the Web Audio API.
Choose your preferred output bit depth — 16-bit for compatibility or 32-bit float for maximum precision.
Click "Convert to WAV" to pack the PCM samples into a standard WAV container.
Click "Download WAV" to save the converted file directly to your device.

Use cases

Open FLAC files in DAWs or audio editors that accept only WAV input.
Convert a FLAC track to WAV for burning to CD (CD-DA requires 16-bit 44.1 kHz WAV).
Quickly verify that a FLAC file decodes without errors before archiving.
Prepare audio for software that strips FLAC metadata but accepts embedded WAV chunks.
Convert small FLAC samples or sound effects to WAV for game engine import.
Losslessly round-trip between FLAC and WAV without installing FFmpeg or Audacity.
Check file duration, sample rate, and channel count before conversion.
Convert FLAC files on a locked-down machine where installing software is not permitted.
