# Encode & Decode

Encoding rewrites data in a different alphabet so it can pass through systems that accept only certain characters, such as URLs, email or JSON. Percent-encoding turns a space in a URL into %20, and Base64 turns every 3 bytes into 4 characters. Anyone can reverse an encoding, so it never keeps data secret.

## Tools

- Base64 Encode and Decode (Coming soon): Encode text to Base64 or decode a Base64 string back to readable text.
- URL Encode and Decode (Coming soon): Percent-encode text for use in a URL, or decode an encoded URL back to readable text.
