- Description
- The ATK (Andrew Toolkit raster object) file type is a raster image format used by the Andrew Toolkit, a graphical user interface development system developed by Carnegie Mellon University. ATK files store both vector and bitmap graphics and are used to create graphical user interfaces for applications.
- Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
