What this tool does

Base64 Encoder/Decoder converts UTF-8 text to Base64 and decodes valid Base64 input back into text.

When to use it

Use it for quick checks around tokens, payload snippets, small config values, or documentation examples that need Base64 conversion.

How it works

Choose encode or decode, paste the text, and copy the output. Invalid Base64 gets a friendly error instead of a silent shrug.

Useful for

  • Decode small Base64 snippets while debugging.
  • Encode example text for documentation or test data.
  • Check whether a pasted Base64 value is valid text.

Questions before the button mashing

Is Base64 encryption?

No. Base64 is encoding, not security. Anyone can decode it if they have the text.

Can this handle Unicode text?

Yes. The tool encodes and decodes UTF-8 text, so normal Unicode characters are supported.
