Generation loss — quality may degrade
AAC uses lossy compression, and so does AVI. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your AAC file may contain MP4 atoms, iTunes tags metadata. AVI has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Default format on Apple devices (iTunes, Apple Music)
Your device saves files in AAC by default (Apple devices (iTunes, Apple Music)). Most people convert because the files won't open on other devices — AVI is universally supported and will work everywhere.
What compression artifacts to expect
AVI lossy compression can produce codec-dependent. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

AVI (Audio Video Interleave) is Microsoft's legacy video container, widely compatible but often large.
Full Name: AAC uses Advanced Audio Coding, while AVI uses Audio Video Interleave. Compression: AAC uses Lossy, while AVI uses Lossy. Color Depth: AAC uses —, while AVI uses 8-bit.
When you convert AAC to AVI, the goal is to improve file compatibility across devices. AAC uses lossy compression, and so does AVI. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible. Understanding these technical differences helps you choose the right format for your workflow.
Your AAC file is decoded and re-encoded as AVI. The conversion involves 4 steps: (1) your aac file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in avi format with optimal settings, (4) the converted file is ready for download.

Should You Convert AAC to AVI?
When to Convert
- ✓You need just the audio track from a video recording
- ✓You're creating a podcast or audio file from video content
- ✓You captured this file on Apple devices (iTunes, Apple Music) and need to share it with others
- ✓You need maximum device and software compatibility
When NOT to Convert
- ✗You're converting just because the file "seems old" — re-encoding lossy-to-lossy always degrades quality
Common Mistakes When Converting AAC to AVI
"I'll convert to AVI and then back to AAC — it'll be the same"
Each lossy conversion cycle permanently degrades quality. Going AAC → AVI → AAC will produce a noticeably worse file than the original. Always keep your source file.
