Derived from "apex" which means the top or highest part of something, in this context means A-grade pixels.
How it works
Find an X post with image
Open the image in a new tab
The default image URL uses parameters like ?format=jpg&name=large, which limits resolution.
a-pix automatically rewrites the URL to ?format=jpg&name=orig, fetching the original size and quality. orig name fetches original size and quality of the image.
