ESSE - Easy Sprite Sheet Editor is
an app that helps you to crop and resize multiple
images at once and after that combine them.
It is really useful when you have multiple images
(i.e. exported from a software like
Adobe Premiere Pro or Adobe After Effects) and
you want to combine them to a single sprite sheet.
The app is Open Source.
