Base64 Encoder/Decoder

Convert plain text to Base64 encoding, or decode a Base64 string back to readable text. Base64 is commonly used to embed binary-safe data in text formats like JSON, URLs, or email, and this handles full Unicode text correctly, not just plain ASCII.

Frequently asked questions

Does this handle special characters and emoji?

Yes, the encoder is Unicode-safe, so accented characters, emoji, and non-Latin scripts round-trip correctly.

Is Base64 encryption?

No. Base64 is an encoding, not encryption, it provides no security or confidentiality, only a way to represent binary-safe data as text.

What happens if I try to decode invalid Base64?

The tool shows an error rather than silently producing garbled output.
