\* Note that oxipng is not a brute-force optimizer. This means that while higher optimization levels
are almost always better or equal to lower levels, this is not guaranteed and it is possible in
rare circumstances that a lower level may give a marginally smaller output. Similarly, using Zopfli
compression (`-z`) is not guaranteed to always be better than without.

## APNG support
Oxipng currently only supports limited optimization of animated PNGs (APNGs). It can perform
alpha-optimization, refiltering and recompression of all frames, but all transformations will be
disabled. For best results, it is recommended to use another tool such as
[apngopt](https://sourceforge.net/projects/apng/files/APNG_Optimizer/) prior to running Oxipng.
