Types of audio files

Each audio format has its own unique features and uses, so knowing which one to choose can greatly impact the quality and compatibility of your converted file.


MP3 (MPEG-1 Audio Layer III) is one of the most popular file formats that is widely used for music and podcasts. It is a compressed format. This means it takes up less storage space but may slightly compromise sound quality.

Best for: Sharing and streaming audio files online.


WAV (Waveform Audio File Format) is an uncompressed audio format that provides high-quality sound without loss of data. In comparison to other formats, WAV files tend to have a larger file size, which makes them less ideal for online sharing or streaming.

Best for: Professional audio recording and editing needs.


WMA (Windows Media Audio) is a file format developed by Microsoft. It is a proprietary compression format designed to efficiently encode and compress digital audio files while maintaining a reasonable level of sound quality.

Best for: Windows-based devices and online streaming for reduced file sizes.


AIFF (Audio Interchange File Format) is a lossless audio format commonly utilized on Apple devices. It offers high-quality sound and is supported by most media players. However, like WAV files, AIFF can be quite large.

Best for: Professional audio applications, especially those developed by Apple.


FLAC (Free Lossless Audio Codec) is a compressed format that retains the full quality of the original file. This makes it a preferred choice for audiophiles and music enthusiasts.

Best for: High-quality audio with no loss of the original sound.


ALAC (Apple Lossless Audio Codec) is a lossless audio format. It is similar to FLAC but compatible with Apple devices and software.

Best for: Archiving high-quality audio on Apple devices.


AAC (Advanced Audio Codec) is a compressed format that was created by Apple as a substitute for MP3. It offers better sound quality at lower bit rates.

Best for: Mobile devices with limited storage space.


OGG (Ogg Vorbis) is an open-source, royalty-free audio compression format. It is often used as an alternative to proprietary audio codecs like MP3.

Best for: Streaming and gaming.


M4A (MPEG-4 Audio Layer) is a container format that can store audio encoded with various codecs, including AAC. Commonly used in iTunes and Apple devices.

Best for: iTunes and listening on Apple devices.


MIDI (Musical Instrument Digital Interface) is a protocol that enables electronic musical instruments, computers, and other devices to communicate with each other.

Best for: Communicating musical information between computers and electronic instruments, not for storing actual audio.

Knowing the different formats will help you make an informed decision when converting your audio files. Consider the purpose and platform where you are going to use the file to determine which format will work best for you.
