About Encoding & Decoding

Base64 encodes binary data as ASCII text, commonly used for embedding images, email attachments, and data URIs.

URL Encoding (percent-encoding) converts special characters to %XX format for safe use in URLs and query strings.

HTML Entity Encoding replaces characters like < > & with their entity equivalents to prevent XSS and render correctly in HTML.

Hexadecimal Encoding converts each byte to its two-digit hex representation, useful for debugging and binary data inspection.
