Does converting FLAC to WAV lose quality?

No. FLAC is lossless, so decoding it gives back the exact samples that were encoded. The WAV is written as 16-bit PCM, which is what nearly every FLAC (every CD rip, for instance) already is.

Why is the WAV so much bigger than the FLAC?

Because the compression has been removed. Expect the WAV to be roughly 1.5 to 2.5 times the size of the FLAC; that is the whole point of FLAC in the other direction.

Where did my tags and album art go?

WAV has no standard tag system, so title, artist and artwork cannot be stored in it. The audio is unaffected. Keep the FLAC if you want the metadata.

Can I burn the WAV to an audio CD?

Yes. Audio CDs need 44.1 kHz, 16-bit stereo. A FLAC ripped from a CD converts to exactly that; burning software will resample anything else.

Is there a size limit?

Large files are limited by your device's memory, since the input and the output both sit in RAM. WAV itself tops out at 4 GB, about six and a half hours of CD-quality stereo.

Why unpack a FLAC at all

FLAC is the better format for storing music, so the reason to turn it back into WAV is nearly always a piece of software or hardware that insists on it:

Older versions of Audacity, Pro Tools, Reaper and other editors that import WAV but not FLAC.
Hardware samplers, drum machines and DJ decks that read WAV from a USB stick or SD card.
CD-burning programs, which want 44.1 kHz 16-bit PCM and nothing else.
Video editors such as Premiere, DaVinci Resolve and iMovie, where WAV is the safest audio to drop on a timeline.
Car stereos and older MP3 players that list WAV support but not FLAC.

What comes out

Your browser's FLAC decoder reconstructs the original samples and Tinyvert writes them straight into a WAV container as 16-bit PCM. There is no encoder involved, so the conversion runs as fast as the file can be read. Sample rate and channel count are kept: a 44.1 kHz stereo FLAC becomes a 44.1 kHz stereo WAV, a 96 kHz mono file stays 96 kHz mono.

FLAC input	WAV output
4-minute pop track, 28 MB	About 42 MB
Full CD rip, 300 MB	About 650 MB
One-hour interview, 180 MB	About 620 MB

Bit-perfect, with one caveat

Almost all FLAC in circulation is 16-bit, and for those files the WAV contains the identical samples: a checksum of the audio matches the source. Studio masters at 24-bit are written at 16 bits, which is still CD quality and fine for burning, editing rough cuts or playback, but if you need the full 24-bit word length for mastering work, keep the FLAC as your source.

Tags do not travel, and that is the format's fault

FLAC carries artist, album, track number and cover art in Vorbis comments. WAV predates all of that and has no agreed place for it, so the converted files show only their filenames. Tinyvert keeps the original filename, so 03 - Blue Monday.flac becomes 03 - Blue Monday.wav and the folder still sorts correctly.

Going back is painless: WAV to FLAC restores the compression without any loss. For phones and cars that want small files, FLAC to MP3 is the usual answer, and MP3 to WAV covers the case where the source was never lossless to begin with.
