carta

Carta is a command-line document converter written in Rust that translates between markup formats like Markdown, HTML, LaTeX, and many others. It functions as both a standalone CLI tool and an embeddable library, offering a faster and smaller alternative to pandoc. The tool supports 33 formats across multiple categories including the Markdown family, HTML, LaTeX, wikis, and data interchange formats.

Designed for developers and users who need quick conversions without heavy dependencies, carta delivers significant performance gains—often 15–35× faster than pandoc on typical tasks—while using a fraction of the binary size and memory. The maker notes that approximately 90% of the codebase was generated with an LLM to accelerate format support.
