How this url tool helps
This URL encoder and decoder makes percent-encoding predictable when you are building query strings, debugging redirects, inspecting analytics links, or preparing API parameters. Component mode uses encodeURIComponent for individual values, while full-URL mode preserves structural characters such as slashes, colons, and question marks. Decode mode turns percent escapes back into readable Unicode text and reports malformed sequences instead of producing confusing output. You can copy the result, load a realistic example, and keep recent values in local browser history. The tool is useful for UTM parameters, search links, callback URLs, slugs, and form data. It runs entirely in the browser and does not validate whether a destination exists, so private or internal URLs are not contacted or exposed. Clear labels explain when to encode a complete URL versus only a component.
