FLIF – Free Lossless Image Format

http://flif.info/

FLIF is a novel lossless image format which outperforms PNG, lossless WebP, lossless BPG and lossless JPEG2000 in terms of compression ratio.

According to the compression experiments we have performed, FLIF files are, on average:

• 26% smaller than brute-force crushed PNG files,
• 35% smaller than typical PNG files,
• 37% smaller than lossless JPEG 2000 compression,
• 15% smaller than lossless WebP,
• 22% smaller than lossless BPG.
