WAV to M4A (AAC) compresses lossy for a much smaller file that plays smoothly on iPhone and iTunes. Raise the bitrate if you want to keep more detail.
About WAV
Uncompressed lossless format
WAV typically stores audio as uncompressed PCM, preserving the exact original signal. It is ideal for editing and professional use, but produces large files.
- Lossless and uncompressed
- Simple structure, easy to edit
- Large file size, not ideal for streaming
About M4A
Common audio container in Apple ecosystem
M4A is an MPEG-4 audio container, usually AAC or ALAC encoded, widely used across Apple devices and iTunes with a good balance of size and quality.
- Good balance of size and quality
- Native to the Apple ecosystem
- Limited support on some non-Apple players
WAV to M4A FAQ
Will converting WAV to M4A lose quality?
Converting lossless WAV to lossy M4A will introduce quality loss. For best results, choose a higher bitrate in the advanced settings.
Will the file size change after conversion?
Converting to a lossless format (WAV) usually increases size, while converting to a lossy format (MP3, AAC) usually decreases it, depending on the chosen bitrate and sample rate.
How do I batch convert WAV to M4A?
Just drop multiple WAV files in; they are converted to M4A one by one via a queue. You can download them individually or as a single ZIP.
