+q: Why is there no support for common formats like GIF or PNG?
+
+a: The short answer is simply that the built-in support in ImageIO for these formats are good enough as-is.
+If you are looking for better PNG write performance on Java 7 and 8, see [JDK9 PNG Writer Backport](https://github.com/gredler/jdk9-png-writer-backport).

 q: What about JAI? Several of the formats are already supported by JAI.

+a: While JAI (and jai-imageio in particular) have support for some of the same formats, JAI has some major issues.
 The most obvious being:
 - It's not actively developed. No issues has been fixed for years.
 - To get full format support, you need native libs.
