The Free Lossless Image Format File (FLIF) is a digital image file format designed to provide high-quality lossless compression for images. Unlike lossy formats like JPEG, FLIF preserves all the original image data without any degradation, ensuring that images are compressed without sacrificing any detail or clarity. This makes FLIF an ideal choice for applications where image quality is paramount, such as digital archives, professional photography, and graphic design. FLIF also incorporates advanced features such as support for high dynamic range (HDR).
Image file format related to the .PNG format, but uses lossy compression like standard .JPG files; developed as a sub-format for .MNG objects, but can also be used as a standalone raster image format.
