Frequently Asked Questions
The URL Encoder/Decoder tool uses JavaScript's built-in encodeURIComponent() and decodeURIComponent() functions. Encoding converts unsafe characters (like spaces and special symbols) into a URL-safe format using the '%' followed by two hexadecimal digits (e.g., space becomes %20). Decoding reverses this process back into a human-readable string.
The strict encoding option is essential for highly technical contexts, such as security testing or complex API parameter submission. It forces the encoding of characters that standard encoding often skips (like single quotes or parentheses), ensuring the resulting URL is universally compliant with all security standards.
