sic is an image crate[1], CLI front-end. It allows you to perform image operations on images and to convert images between formats from the CLI.

Currently, the following input (decoding) formats are supported:
* BMP, GIF, ICO, JPEG, PNG, PBM, PGM, PPM, PAM and TIFF and WebP

The following output (encoding) formats are supported:
* BMP, GIF, ICO, JPEG, PNG, PBM, PGM, PPM and PAM

For both encoding and decoding, not all variations of the supported formats are supported.
Animated images are currently not supported, however a specific image frame may be selected if the image is a GIF.
