Atomize

Atomize is an Android application for compressing PNG images, aimed at reducing file size while keeping the PNG format. It works on images already stored on the device, so the usual workflow is to pick a file, run compression, and keep the smaller output. The focus is on one format and one task rather than general image editing.

Size reduction of this kind is useful when images are headed somewhere with limits: message attachments, upload forms, repository assets, or documentation where large screenshots add unnecessary weight. Because the application deals with PNG specifically, images in other formats fall outside its scope.

Atomize is distributed under the GNU General Public License, version 3 only, which requires derivative works to be released under the same terms and does not permit moving to a later version of the licence. It is published for Android, with no other platform listed in the available facts.
