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. ## Related tools - [Batch Audio Converter](https://elysiatools.com/en/tools/audio-batch-converter): Convert multiple audio files between different formats like MP3, WAV, FLAC, AAC, OGG, Opus with quality settings and batch processing - [Audio Codec Swap](https://elysiatools.com/en/tools/audio-codec-swap): Change the codec of an audio file within a chosen output format - [Audio Format Converter](https://elysiatools.com/en/tools/audio-converter): Convert audio files between different formats like MP3, WAV, FLAC, AAC, OGG with quality settings and volume adjustment - [Batch WAV Audio Converter](https://elysiatools.com/en/tools/batch-wav-converter): Convert multiple WAV files to OGG, AAC, M4A, and OPUS formats with quality settings, bitrate control, and batch processing - [Audio Cutter](https://elysiatools.com/en/tools/audio-cutter): Cut and extract audio clips from audio files with precise time selection - [Audio Decrackler](https://elysiatools.com/en/tools/audio-decrackle): Remove crackles and subtle impulsive noise from audio files.
