Questions
What is Base64?
Base64 is a way to represent binary or arbitrary text using only 64 printable ASCII characters, making it safe to embed in emails, JSON, HTML attributes, and data URLs.
Why is this tool UTF-8 safe?
Emoji and accented letters are multiple bytes in UTF-8. This tool converts the text to its raw UTF-8 bytes before encoding, so the Base64 round-trips correctly for any language or symbol.
Is my text sent anywhere?
No. Encoding happens entirely in your browser using built-in Web APIs. Nothing you type is transmitted to any server.
