Apple's audio format using AAC. Native support on iOS/macOS.
The audio converter supports conversion between all major formats including MP3 (most popular), WAV (uncompressed), AAC (advanced coding), FLAC (lossless compression), OGG (open source), and M4A (Apple format). You can convert from any supported format to any other format with high quality preservation.
MP3 is the most compatible format with good compression. WAV is uncompressed with highest quality but large file size, ideal for professional editing. AAC offers better quality than MP3 at same bitrate and is used by Apple and YouTube. FLAC provides lossless compression with perfect quality while reducing file size by 40-60%. OGG is open-source with good quality. M4A uses AAC codec with native iOS/macOS support.
Quality settings determine the bitrate and compression level during conversion. High quality maintains best audio fidelity with larger file sizes (suitable for music listening). Medium quality balances quality and file size (good for most uses). Low quality creates smaller files with reduced fidelity (suitable for voice recordings or when storage is limited). Lossless formats (FLAC, WAV) maintain perfect quality regardless of setting.
Conversion speed depends on file size and format complexity, but most conversions complete in seconds. The tool uses optimized browser-based processing for fast results. Converting a 5-minute MP3 to WAV typically takes 10-20 seconds. Larger files or lossless format conversions may take longer. All processing happens locally in your browser for maximum speed and privacy.
Quality loss depends on the conversion path. Converting from lossy to lossless (MP3 to FLAC) doesn't improve quality but maintains existing quality. Converting from lossless to lossy (WAV to MP3) reduces file size with some quality loss. Converting between lossy formats (MP3 to AAC) may cause minimal additional loss. For best results, use high quality settings and avoid multiple conversions. WAV and FLAC maintain perfect quality.
Currently, the tool processes one audio file at a time to ensure optimal quality and performance. After converting a file, you can immediately upload and convert another. The conversion process is fast, typically completing in seconds, allowing you to process multiple files quickly in succession.
Choose based on your needs: MP3 for universal compatibility and general use. WAV for professional audio editing or archiving original quality. AAC for better quality than MP3 at same file size, especially for Apple devices. FLAC for lossless archiving with compression. OGG for open-source projects and gaming. M4A for iOS/macOS native support. Consider your target platform, quality needs, and storage space.
