Why convert AVI to AAC?

Converting to AAC helps when your next tool, device, website, or sharing workflow needs mobile playback, streaming, and compact high-quality audio.
Best uses for AAC
AAC is useful for mobile playback, streaming, and compact high-quality audio. AAC is lossy and often more efficient than MP3 at similar bitrates. Use this output when compatibility, editing needs, upload requirements, or file size make AAC the better fit.
Before you convert
Check duration, volume, playback support, and whether the output uses lossy or lossless compression before deleting the original. Keep the original AVI file until the converted AAC file has been reviewed successfully.
