About Base64 to JSON Decoder

Decode Base64 payloads to JSON with tolerant parsing and pretty output. This online utility is designed for a focused task, with clear status messages and browser-friendly fallbacks. Local-file work stays in the browser unless the page clearly identifies a network-backed lookup; URL mode contacts the source you provide and remains subject to that source's CORS policy.
