Encode any text to Base64 or decode Base64 strings back to readable text. Supports Unicode characters. Real-time conversion as you type.
A Base64 encoder/decoder converts data between its original format and Base64 encoding, a method that represents binary data using ASCII characters. Base64 encoding is widely used in web development for embedding images in CSS and HTML, encoding data in URLs, and handling binary data in JSON. Our browser-based tool supports both encoding (text to Base64) and decoding (Base64 to text) operations. All conversions happen instantly in your browser, making it safe to encode sensitive data like API tokens without exposing them to external servers.
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to embed data in text-based formats.
Yes! Our tool properly handles Unicode characters by first encoding them with encodeURIComponent before Base64 encoding.
The decoder will show an error message if the input is not valid Base64. Common issues include missing padding characters (=) or invalid characters.
No, Base64 is encoding, not encryption. It's easily reversible and should not be used for security purposes.
