About the URL Encode/Decode
URLs can only safely carry a limited set of ASCII characters — spaces, ampersands, question marks, and non-Latin characters all have to be percent-encoded (like %20 for a space) before they can go into a query string or path segment without breaking the URL or being misread as a delimiter. This tool applies that percent-encoding, and reverses it when you need to read an encoded string back to plain text.
It's a common step when building a query parameter that contains user input, debugging a redirect URL that's failing because of an unencoded special character, or decoding a tracking link to see what data it's actually passing. Note that this encodes for query-string safety (matching JavaScript's encodeURIComponent behavior) rather than encoding an entire URL wholesale, which would break the scheme and domain.
Frequently Asked Questions
What is URL encoding?
URL encoding (also known as percent-encoding) converts non-ASCII or reserved characters in URLs into a safe ASCII format prefixing hex representations with percent signs.
Why is URL encoding necessary?
URLs can only contain a limited set of ASCII characters. Reserved characters like ?, &, =, and spaces must be encoded if they are part of dynamic query parameter values.
