Speaking the Web's Language

Computers and the internet rely on specific formats to transmit data safely. Text encoding ensures that your characters don't break URLs, confuse browsers, or get corrupted during transfer.

Common Formats

URL Encoding

Replaces unsafe characters with a % followed by two hexadecimal digits. Essential for putting text into a web address.

Base64

Converts binary data (or text) into a set of 64 safe ASCII characters. Used for email attachments and embedding images.

HTML Entities

Replaces reserved characters like <, >, and & with safe codes (e.g., &lt;) to prevent them from being interpreted as HTML tags.

Security & Compatibility

Encoding isn't just about compatibility; it's a key security practice. Properly encoding user input prevents Cross-Site Scripting (XSS) attacks by ensuring that malicious scripts are treated as harmless text rather than executable code.
