FAQ

Base64 Questions & Answers

What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format using 64 printable characters (A-Z, a-z, 0-9, +, /). It is widely used in email, data URIs, and authentication tokens.

Does this tool handle emojis and Unicode characters?

Yes. Traditional browser btoa() functions fail on non-ASCII characters. Our tool uses UTF-8 byte array processing with the Web TextEncoder and TextDecoder APIs, ensuring symbols, accented characters, and emojis encode and decode accurately.

Is my Base64 text uploaded to any server?

No. Everything runs strictly on your client machine in your browser. Sensitive strings and keys are never uploaded.
