I couldn't find any information on "Authority PNG" in the provided search results. The search index lacks direct matches, and I don't have enough information to provide an accurate answer.

However, I can suggest some tools mentioned in the search results that might be related to image optimization:

* Ambiguous PNG Packer: This tool allows you to craft PNG files that appear different in Apple software.
* Other tools for optimizing JPEG, PNG, MP4, and GIF are mentioned in the comment section of the original post.

If you have any more specific information or context about "Authority PNG," I'd be happy to try and help further.
