Decompresses FLAC into WAV. This is one of the few conversions on this site that loses absolutely nothing — FLAC is lossless, so the WAV contains exactly the same samples.
Bit-for-bit identical
The file roughly doubles in size, because FLAC typically compresses to 50–60% of WAV. Nothing else changes — same sample rate, same bit depth, same audio.
Why you would want the larger file
If everything in your chain reads FLAC, keep the FLAC — it is the same audio in half the space.
Bit depth
Both are lossless, so nothing is decided here

Questions
- Is any quality lost?
- None. FLAC is lossless, so the WAV contains exactly the same samples.
- Why is the file twice as big?
- FLAC compresses losslessly to about half the size of WAV. Decoding restores the uncompressed form.
- Do I get 24-bit?
- No — 16-bit PCM, the most compatible variant. Use a desktop tool if you need to preserve a 24-bit depth.
- Is my file uploaded?
- No. The demuxing, decoding and encoding all happen in this tab using the browser’s own media stack plus a WebAssembly encoder. A recording can be an interview, a lecture, a private call — none of it is transmitted. Turn your Wi-Fi off after the page loads and it still works.
- How large a file can I convert?
- There is no imposed limit, only your device’s memory — around 2 GB in a desktop browser and 400 MB on a phone, since the file is held in memory while it converts. A two-hour video converts in well under a minute on a laptop.
