What is a WAV file?+
WAV is an uncompressed audio format that preserves full quality, often used in recording and editing. Files are much larger than compressed formats like MP3.
Why convert WAV to MP3?+
MP3 files are far smaller than WAV, making them easier to email, upload, or store, while still sounding great for everyday listening.
Does converting WAV to MP3 lose quality?+
Yes, MP3 uses lossy compression, so there's some quality reduction. FixTheFile uses a high bitrate so the difference is barely noticeable for most listening.
Can I convert WAV to FLAC instead, for no quality loss?+
Yes — FixTheFile also converts WAV to FLAC, a lossless format, if you want to keep full audio quality in a smaller file.
