+**YOGA** is a command-line tool and a library that can:
+
+* convert and optimize images from various format to JPEG and PNG,
+* convert and optimize 3D models from various formats to `GLB`_.
+
+**Images** are opened using Pillow_ and optimized using Guetzli_ (for JPEGs) and
+Zopflipng_ (for PNGs).
+
+**3D Models** are converted and optimized using assimp_. If models contain or
+reference images, they are processed by YOGA's image optimizer.
