Encoding & Decoding Tools

Encoding tasks tend to be tiny, but they show up everywhere: debugging payloads, cleaning copied markup, escaping template snippets, and validating JSON before it hits an API. This hub keeps those fast browser-based encoding and formatting tools together so you can move between Base64, URLs, HTML entities, and JSON without breaking focus or writing a throwaway script.
