What Is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data using 64 printable ASCII characters. It is commonly used to embed images in CSS/HTML, encode binary payloads in JSON APIs, and store data in environments that only support text.
🔗 URL Encoding
URL encoding (percent-encoding) replaces characters that have special meaning in URLs with a % followed by a two-digit hex code. This is essential when passing query parameters that may contain spaces, ampersands, or non-ASCII characters.
