URL Formatter
Encode and decode URLs, parse URL components and query parameters
URL Formatting Tips
- Always encode query parameter values that contain special characters like &, =, or spaces.
- Use the parse function to break down complex URLs into their individual components.
- Double-encoding is a common bug — decode first if you suspect already-encoded input.

Frequently Asked Questions
Common questions about Url Formatter formatting answered
Yes, our URL formatter is completely free with no registration required. All processing happens in your browser.
encode() encodes the entire URL, preserving structural characters like :// and /. encodeURIComponent() encodes everything including / and ?, used for query parameter values.
Yes. Use the Parse button to break any URL into protocol, hostname, port, pathname, search parameters, and hash fragments.
Yes, our tool supports internationalized domain names (IDN) and Unicode characters in URL paths and query parameters.
Characters like spaces, &, =, ?, #, /, and non-ASCII characters should be percent-encoded in URLs. Reserved characters have special meanings in URL structure.
The WHATWG URL Standard - the same parsing algorithm browsers implement and URLSearchParams is built on. It replaces the older RFC 3986 grammar for web work (the WHATWG spec is stricter and browser-defined); components shown are scheme, username/password, host, port, path, query (parsed into decoded pairs), and fragment.
Every component decodes and re-encodes correctly per its rules: %2F in a path stays encoded (it would otherwise become a delimiter), reserved characters in query values (&, =, +) are preserved through encode/decode round-trips, and non-ASCII characters (IRIs) convert between raw Unicode and percent-encoded UTF-8 both ways.
The practical list: mixed-case schemes and hosts (HTTP://EXAMPLE.COM works but is non-canonical), default ports (443 on https) that should be dropped for canonicalization, unencoded spaces and Unicode in query strings, duplicate query keys (shown grouped), and IDN homographs (punycode xn-- forms expanded with a homoglyph warning - a known phishing vector).

Formatting and percent-decoding are separate operations. Decoding does not change the original input; retain it when copying signed URLs. Duplicate query parameters and their order are meaningful. WHATWG URL Standard
