Free Lossless Image Format (FLIF)

FLIF is a patent-free open source image encoder which outperforms WebP, JPEG2000, JPEG-XR, BPG image codecs.

FLIF’s homepage with results of comparison is here; FLIF’s codes are here.

To compile FLIF codec in Windows the following operation are required:

• Get FLIF reference codes:

               git   clone   https://github.com/FLIF-hub/FLIF.git

 

• Open the command prompt and go to the directory FLIF\build\MSVC

 

• Run dl_make_vs_x64.bat, the script would download all necessary files and build exe-file: flif.exe, the file is located at the folder        FLIF\build\MSVC\

 

Examples

1) To run FLIF encoder in lossless mode:

flif.exe -e  test.png   -Q100   --overwrite    test.flif

‘-e‘   means encoding

‘-Q100‘ lossless mode

 

2) To run FLIF decoder, output png-file

flif.exe  -d test.flif    test.png
