About Converting FLAC to WAV
FLAC compresses audio losslessly, cutting file size roughly in half versus WAV while preserving every bit of the original. It is the audiophile standard for archiving music. When you need to move away from FLAC, the usual reason is simple: larger than lossy formats.
Converting your FLAC audio file to WAV solves that. WAV is an uncompressed, lossless audio format that stores the full raw waveform. It is the studio standard for editing and mastering, at the cost of large files. In practice you gain uncompressed, lossless quality and standard for editing/mastering. PrivConvert runs the whole FLAC-to-WAV conversion in server memory and deletes your file the instant the WAV is ready — nothing is stored, logged or reused.
When this conversion helps
- You need uncompressed, lossless quality
- You need standard for editing/mastering
- You need no encoding artifacts
- Sharing a FLAC audio file with someone whose software expects WAV
Tips for best results
- WAV preserves quality exactly, so the conversion from FLAC will not introduce any new compression artifacts.
- Files up to 250 MB are supported, and you can batch-convert several FLAC files at once; each is processed privately and deleted immediately.
