WebP lossy images are 25-34% smaller in size compared to JPEG images at equivalent SSIM index. WebP supports lossless transparency (also known as alpha channel) with just 22% additional bytes.
SOIL show description homepage
SOIL is a tiny C library used primarily for uploading textures into OpenGL. It is based on stb_image version 1.16, the public domain code from Sean Barrett. I have extended it to load TGA and DDS files, and to perform common functions needed in loading OpenGL textures. SOIL can also be used to save and load images in a variety of formats (useful for loading height maps, non-OpenGL applications, etc.)
