There is only one file type that uses the .TIFF extension:
Tagged Image File Format
A TIFF file is a graphics container that stores raster images in the Tagged Image File Format (TIFF). It contains high-quality graphics that support color depths from 1 to 24-bit and supports both lossy and lossless compression. TIFF files also support multiple layers and pages.
You can open TIFF files with various image editors since the TIFF format is quite common. Some options include Windows Photos (Windows), CorelDRAW Graphics Suite (Windows and macOS), Adobe Photoshop (Windows and macOS), and Apple Preview (bundled with macOS).
NOTE: You can also open TIFF files with Google Photos in a web browser, Chrome OS, and Android and iOS devices.
