What is this tool?
Encode strings into Base64 formats, decode Base64 back into raw text, or convert files into downloadable binary streams locally in your browser tab.
When to use it?
Ideal for decoding base64-encoded email payloads, encoding basic authentication credentials, or formatting images/files into base64 data URLs.
