URL Encoder / Decoder

URL encoding (also called percent-encoding) converts characters that are not allowed or have special meaning in URLs into a safe format using the % sign followed by two hexadecimal digits. For example, a space becomes %20 and an ampersand becomes %26. This is essential when including user input or special characters in URL query strings, path segments, or form submissions. URL decoding is the reverse — it converts percent-encoded sequences back to readable text.
