Frequently asked questions
Why convert M4A to OGG?
Opus gives better quality per bit than AAC, and OGG avoids proprietary formats entirely — a common requirement in open-source projects.
Does this keep my file lossless?
No — AAC and Opus are both lossy, and re-encoding adds a little loss. This is about compatibility and size, not fidelity.
Can I convert back to M4A later?
Yes — use the OGG to M4A tool, but expect a small quality cost for every re-encode.
