About Base64 encoding
Base64 represents binary or text data using 64 safe ASCII characters, which makes it ideal for embedding data in URLs, JSON, data URIs, HTML and email. Developers reach for it constantly when debugging tokens, configuration values and API payloads. This converter handles full UTF-8, so emoji and non-English text are preserved exactly, and because it runs locally nothing you paste is ever uploaded.
