Half the size. The exact same bits. We'll prove it.
FLAC is zip for audio: it shrinks a WAV, and decoding gives back every sample unchanged. The compression level only changes how hard the encoder works. Pick a recording and a level; the fingerprint never changes.
Open songs, voice memos or old archives and save them as MP3, AAC, FLAC, Opus, WMA, AC3, AMR or any of 19 more. Pick a quality preset or an exact bitrate, convert the whole batch in one pass, then download each file or one ZIP.
ffmpeg -i harbour-lights.wav -vn -map_metadata 0 -ar 48000 -ac 2 -c:a libmp3lame -b:a 192k -f mp3 harbour-lights.mp3Sound waves are smooth, so each sample is close to what the last few predict. FLAC saves the prediction rule plus the small leftover error. Small numbers need fewer bits. Quiet, simple music leaves tiny errors; noisy, dense music leaves big ones.
WAV tagging is patchy: many apps write nothing, and others use fields that music players ignore. FLAC has one well-supported tag system and embedded cover art. We copy what we find and let you fill the gaps before converting.
FLAC used to be for audiophiles only. Today phones, browsers and streaming boxes play it. The awkward one is Apple's Music app, which only imports its own lossless format.
What people usually do with the rest of their audio.
Yes, WAV to FLAC conversion is completely free with no signup, no watermark, and no usage limit. Convert as many files as you need.
No. The WAV to FLAC converter runs in your browser when your file is supported there, so the file stays on your device for that workflow, reducing server exposure for that workflow. Check which processing mode is in use before you upload anything sensitive.
Most WAV to FLAC conversions finish in under a minute. Larger files take proportionally longer, but everything happens locally so there is no sign-up wait.
That comes down to the formats at each end. A lossless conversion changes nothing you can measure. A lossy one shaves the file down and takes a small amount of quality with it.
Yes. The WAV to FLAC converter works on phones, tablets, and desktops in any modern browser including Chrome, Safari, Firefox, and Edge.
