Base64 Encode / Decode

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for transmitting data over media designed to handle text.

Common Use Cases:

• Embedding images in HTML/CSS (data URLs)
• Encoding data in JSON or XML
• Email attachments (MIME)
• Authentication tokens (JWT)
• Storing binary data in databases or config files

URL Safe Mode: Uses '-' and '_' instead of '+' and '/' to make the encoded string safe for URLs and filenames.
