Does converting FLAC to WAV reduce quality?

No. Both FLAC and WAV are lossless formats. Converting between them produces audio that is bit-for-bit identical to the original.

Why is the WAV file much larger than the FLAC file?

FLAC uses lossless compression to reduce file size by 40-60%. WAV stores raw uncompressed audio samples, so it is significantly larger.

Is WAV compatible with all software?

Yes. WAV is the most widely supported audio format. Every digital audio workstation, video editor, and operating system supports it natively.

Are my files uploaded to a server?

No. All conversion runs in your browser using WebAssembly. Your FLAC files never leave your device.
