GifTools 1.4.0 | macOS | 9 mb
Romanysoft GifTools is designed for Mac users to convert animated images from GIF to APNG format or from APNG to GIF format. When processing GIF to APNG conversion, it generates APNG files with good quality, and meanwhile removes white pixels around the edges in the original GIFs.

In addition, it allows users to resize images to the exact pixels or proportion you specified before format conversion. For example, when you need to change a 512 x 512 animated Gif file to a 150 x 150 APNG file on a Mac computer, you can use Romanysoft GifTools to achieve that purpose. Compatibility: OS X 10.9 or later 64-bit
