Frequently asked questions
About Any to MP3
Audio to MP3 converts many audio formats into the most widely compatible audio format. Use it for WAV, FLAC, AAC, OGG, M4A, WMA, AIFF, voice recordings, music demos, lectures, and files that need to play almost anywhere. MP3 is a delivery format. It is smaller and more compatible, but it is lossy. Keep the original file if it is a master recording or if you may edit it later. Choose bitrate based on content: lower for speech, higher for music. Then listen before uploading or sending.
