WAV (.wav) · Max 20 MB
WAV files are uncompressed and huge. M4A uses lossy compression to shrink them by 90% or more. The size reduction is significant for sharing, uploading, and storage.
For email attachments, 128-192kbps works well. For music sharing, use 256-320kbps. AudioUtils lets you drop your file and convert instantly. No upload to a server, no waiting.
WAV is lossless. Converting to M4A reduces file size at the cost of some audio data. Use a high bitrate to minimize loss. Choose the right bitrate for your use case. Higher bitrate means better quality but larger files.
