FLIF (Free Lossless Image Format) is a lossless image format and reference implementation in C++ based on MANIAC compression, outperforming PNG, lossless WebP, and lossless JPEG2000 in compression ratio. It includes a command-line encoder/decoder, shared libraries, and supports progressive interlacing so partial downloads render as reasonable lossy previews.
Use cases
- compress images losslessly smaller than PNG or WebP
- encode and decode .flif image files from the command line
- serve progressively-loading lossless images over slow connections
- integrate a lossless image decoder into an application via libflif_dec
- convert PNG images to a more compact lossless format
When to choose
- you need maximum lossless compression ratio for images
- you want progressive rendering of partially downloaded images
- you are working with legacy FLIF files or archives
When to avoid
- starting a new project - FLIF is superseded by JPEG XL (libjxl)
- you need actively maintained software or security updates
- you need broad ecosystem or browser support
