Ansizalizer is a terminal user interface for converting images to ANSI art.
The program provides a built-in file browser and a real-time preview of the rendered output. Images can be represented using Unicode block characters, ASCII characters or custom text, with true colour or a limited colour palette.
Ansizalizer supports static images and animated GIFs. It also offers batch conversion, palette generation, dithering, image adjustments, transparency handling, settings presets and export to an ANSI text file or the clipboard.
