UTF-8 to Base64
Encode Unicode text as UTF-8 bytes and then standard padded Base64. Whitespace and line endings in the original text are part of the encoded data.
How to use UTF-8 to Base64
- Enter or paste “Unicode text”. Follow the separators and formatting described in the tool introduction.
- Select Calculate or Process. Review the result and any validation message before copying or downloading available output. Reset clears the result and restores the starting inputs.
Method & assumptions
Unicode text → UTF-8 bytes → standard Base64 alphabet with = padding.
Worked example
Hello becomes SGVsbG8=.

Questions, answered
Does Base64 protect a secret?
No. Base64 is reversible encoding, not encryption. Lone Unicode surrogate halves are rejected instead of being silently replaced.
Does this send my input to a server?
No. This engine processes input locally without network requests. The surrounding website may have its own analytics or scripts; avoid entering sensitive material on an untrusted site. Text fields accept at most 1,000,000 UTF-16 units unless a smaller field limit is stated.
