It converts plain text into Base64 and decodes Base64 back into readable text, including Unicode-safe input.
Base64 often appears in encoded payloads, basic auth values, tokens, binary placeholders, and copied API examples.
No. Base64 is an encoding format, not encryption. Encoded values can be decoded by anyone with the string.
Decode JWT header and payload JSON while debugging auth flows, API tests, and mock tokens.
Encode and decode URL components for query strings, redirects, API debugging, and copied request values.
Paste JSON and format it with consistent indentation after a short debounce delay.
