WAV to FLAC Transformation FAQ
What bitrate will the resulting FLAC file use?
+
A lossy FLAC is encoded at 192 kbps by default. The Audio Quality setting also offers 320 kbps for the best quality and 128 kbps for a smaller file. A lossless FLAC (WAV, FLAC) ignores the bitrate and keeps every sample.
Is WAV to FLAC genuinely lossless?
+
Yes. Both formats keep every sample, so decoding the FLAC returns a bit-identical copy of the audio inside the WAV. Nothing is quantised, nothing is discarded, and the conversion can be repeated indefinitely without accumulating artefacts. What changes is the file size and which software will open it. WAV normally stores raw uncompressed PCM — every sample kept exactly, at whatever bit depth and sample rate was captured. FLAC uses linear prediction plus Rice coding to reach roughly 50-60% of the original size while decoding back to bit-identical PCM.
Can I tag the FLAC with artist and album information?
+
Yes, and it is a genuine gain over WAV, which has nowhere dependable to store any of it. FLAC carries title, artist, album, year, track number and embedded cover art in the container itself, so a music library files it correctly without a manual pass. FLAC gives you WAV fidelity at half the size, with proper metadata tags and embedded artwork, which is why it dominates lossless music libraries.
Will the FLAC play in my car or on older hardware?
+
Often not. WAV is decoded by essentially everything, including car head units and elderly players; FLAC needs software that knows the codec, which standalone hardware frequently does not have. If the destination is a car stereo or a portable player, that is a strong argument for staying on WAV. FLAC is still several times larger than a good lossy file, and Apple’s ecosystem only added support recently and grudgingly.
Will going from WAV to FLAC reduce my audio quality?
+
If WAV is lossy and FLAC is lossless (e.g. MP3 → WAV), the FLAC is no better than the WAV — you cannot recover information already discarded. If WAV is lossless and FLAC is lossy, the FLAC codec recompresses; at 192 kbps the result is transparent for most content.
Can I batch convert hundreds of WAV files to FLAC?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Will the FLAC keep the same sample rate as WAV?
+
By default yes — 48 kHz WAV stays 48 kHz in FLAC. If you need to downsample for compatibility (96 kHz → 44.1 kHz for CD burning), the sample-rate option applies high-quality resampling in the same encode pass.
Can I normalize loudness when converting WAV to FLAC?
+
Not in this step. The converter has no loudness setting and leaves the level as it is. To even out the volume, run the finished FLAC through a Normalize tool on this site.
Will my FLAC play on car stereo, iPod, and Sonos?
+
MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. FLAC plays on Sonos and Android but not on older iPods, and WAV plays on nearly everything but makes large files. There are no device presets on this page, so choose the target format your player supports.
Is my WAV file private during conversion to FLAC?
+
Yes. Uploaded WAV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted FLAC are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
