Base64 Encoder
Encode UTF-8 text to Base64 locally. Encoding is reversible and is not encryption.
What this tool does
Convert UTF-8 text to Base64 in the browser.
How to use it
Paste text. Encode it. Copy the result where the receiving system expects Base64.
Why it matters
A reversible text representation is useful when systems require ASCII-safe data.
Example
Hello world encodes as SGVsbG8gd29ybGQ=.
Understanding the result
Unicode characters are first encoded to UTF-8 bytes.
Limitations
Base64 is not encryption, redaction or a security boundary.
