FAQ

What is the difference between WAV and M4A?

WAV is an uncompressed, lossless format that results in large file sizes, while M4A uses AAC compression to provide high-quality audio in a much smaller, more portable file size.

Will I lose audio quality during conversion?

M4A (AAC) is a lossy format, meaning some data is removed to compress the file. However, at higher bitrates like 256kbps or 320kbps, the difference is virtually indistinguishable to the human ear.

Can I convert multiple files at once?

This tool is designed for single-file processing to ensure optimal performance and conversion accuracy.

What is the maximum file size I can upload?

You can upload WAV files up to 80MB in size.

Does this tool preserve my audio metadata?

Yes, the tool includes an option to keep existing metadata tags like title and artist information when available.
