About the Technology:

WebAssembly provides a way to run code written in multiple languages on the web at near-native speed, with client-side execution that provides a better user experience. By compiling Rust code to WASM, we can leverage the performance benefits of Rust, such as memory safety and thread-level parallelism, directly in the browser.

This tool uses the fastnbt library for parsing NBT (Named Binary Tag) data, and the image library to generate PNG files from the parsed data. The entire process is performed client-side, which allows for rapid processing and minimizes server load.
