- Description
- QTK (Apple QuickTake Picture) is a file format used for digital photos taken with Apple's QuickTake digital cameras. It stores the image in a compressed format and can be opened and viewed with various image viewing software.
- A JPEG XL file is an image saved in a compressed graphic format currently under development by the Joint Photographic Experts Group (JPEG). It supports wide color gamut and HDR (High Dynamic Range), alpha channels and animation frames while providing visually lossless compression. Images can be converted back and forth between JPEG XL and JPEG without loss of quality. Converting a regular JPEG to JPEG XL reduces the file size by 22%. JPEG XL files can be used to store any type of image content.
