Base64 Encoder & Decoder

Encode and decode text to Base64 quickly and securely.

How does it work?

Base64 converts any text into an ASCII-safe string for URLs, HTTP headers or credentials — and it also works in reverse, from Base64 back to readable text.

Paste your content, choose encode or decode and copy the result. It handles accents, emojis and special characters without breaking, and nothing leaves your browser.
