Troubleshooting
- AAC is lossy, so each re-save loses a little more detail. Convert from your original WAV rather than from an earlier AAC export.
- If the file exceeds the limit shown below, compress images, trim video, or split archives before retrying.
- If conversion fails, confirm the extension matches the real format — renaming a file alone does not change its contents.
- Converting a lossy file to a lossless format will not improve its sound quality.
