Converting WAV to FLAC compresses the audio losslessly to roughly 50–60% of its size: no quality loss, bit-perfect decode, every time. It's the standard archival format for anyone ripping CDs, preserving recordings, or building a home music server that values integrity over file size.

The only real cost is CPU time at encode and decode. FLAC adds tagging, cue sheets, MD5 verification of the audio stream, and ReplayGain support that raw WAV cannot carry. WAV's only advantage is that some legacy editing tools cannot read FLAC directly.
FLAC plays on Windows, macOS, Linux, Android, modern iOS (since 11), and every serious music player. Older hardware and some consumer products still skip FLAC; if you're feeding a hardware device, check first.
WAV is Microsoft and IBM's uncompressed PCM container. A stereo CD-quality recording takes about 10 MB per minute. Because nothing is thrown away and nothing is compressed, WAV is the universal working format for recording, editing, and mastering in every major DAW.
FLAC is a lossless compressor: it shrinks PCM audio to roughly 50–60% of its original size and decodes back to a bit-perfect copy. It supports tags, cue sheets, and up to 32-bit / 655 kHz, which makes it the de facto format for CD rips and audiophile music libraries.
Typically 50–60% of the original WAV size. A 40 MB WAV usually compresses to 20–25 MB as FLAC. Compression ratio depends on the audio; dense full-band music compresses less than sparse recordings.
None. FLAC decodes to exactly the same PCM samples the WAV contains. The FLAC spec even includes an MD5 of the decoded audio so you can verify bit-perfect preservation.

Yes. The converter runs entirely in your browser using FFmpeg compiled to WebAssembly. Your audio files are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Files over about 2 GB total can get slow or hit browser memory limits. Process in smaller batches if you run into issues.
