- Description
- The TG4 file type is associated with Tiled Group 4, a format used primarily for storing black and white (monochrome) images. It utilizes the Group 4 compression method, which is a form of TIFF (Tagged Image File Format) compression that is particularly efficient for scanning and storing documents, blueprints, and detailed line art in a compact file size without loss of quality. TG4 files are suitable for archiving or transmitting detailed images where retaining exact detail is crucial. They are commonly used in industries that require high-quality document imaging and archival, such as legal, engineering, and medical fields.
- 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.
