How do I convert FLAC to WAV?

Add your FLAC file to the upload area above, then press Convert. The WAV file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to WAV reduce quality?

No. WAV is a lossless format, so the conversion preserves exactly what is in your FLAC file. Note that it cannot recover detail that was already discarded when the FLAC was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 300 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

FLAC and WAV explained

FLAC compresses audio losslessly, typically to about half the size of WAV. Decompressed, it is bit-for-bit identical to the original — the compression is mathematical, not perceptual.

WAV stores uncompressed PCM audio — the raw samples, exactly as captured. A stereo CD-quality minute is roughly 10 MB, which is the price of having no compression whatsoever.

Where FLAC files come from: Hi-fi music libraries and archival rips of physical media.
Where WAV is used: Recording sessions, sample libraries and audio editing.

FLAC vs WAV

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

FLAC compared with WAV
Property	Source	Target
Compression	Lossless	Uncompressed
Introduced	2001	1991
Browser support	Great on desktop and Android; iOS support is newer.	Universal.

FLAC is stronger at: Lossless — provably identical to the source. Roughly half the size of WAV. Rich metadata and cover art support.
WAV is stronger at: Perfect fidelity with zero compression artefacts. No decoding overhead, so editors scrub instantly. Universally supported.

Why convert FLAC to WAV?

People make this switch when they run into the limits of FLAC: streaming, or converting from an already-lossy source. WAV is the better fit when recording, editing, mastering, or handing audio to another tool.

Be aware of the size trade-off: WAV is uncompressed, so expect the converted file to be considerably larger than the FLAC you started with.

FLAC limitations that prompt the switch: Much larger than MP3 or AAC. Not supported natively by all portable devices. Pointless as a destination for already-lossy audio.
What you give up: Very large files. No standard metadata support worth relying on.

Does converting FLAC to WAV reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.
