Encoding and decoding tools

Encoding and decoding tools for Base64, URL components, query strings, and HTML entities.

Decode copied strings, inspect URL parameters, escape HTML examples, and convert small test values locally.

Common next steps

After decoding a value, developers often format JSON, validate a payload, or copy the cleaned result into a bug report.
