This URL encoder and decoder converts text to and from percent encoded form so that it can be reliably included in URLs, query strings, and HTTP requests. Spaces, non ASCII characters, and reserved symbols can break links or change meaning if they are not encoded correctly. By pasting your text or URL into the tool you can either see the encoded version that is safe for transmission or decode an already encoded string back into human readable form. Developers working with APIs, redirects, and link generation will find this helpful, as will anyone debugging strange looking URLs that contain sequences like percent twenty or percent twoF.
