Use this free online URL Encoder / Decoder to convert ordinary text into URL-safe encoded strings or decode percent-encoded URLs back into readable text. Enter the text in the input area or upload a supported file for processing. Once completed, you can copy or download the converted text for use in web applications, APIs, or data transmission.
URL encoding is commonly used in web development, query strings, form submissions, and APIs to ensure that special characters are transmitted correctly over the internet. It helps preserve characters such as spaces, symbols, and non-English text when included in URLs.
Understanding URL Encoder / Decoder
URL encoding is a method used to represent characters that are not allowed in URLs by replacing them with a percent sign followed by hexadecimal values. For example, spaces are commonly represented as %20, allowing URLs to remain valid and properly interpreted by web servers and browsers.
URL decoding performs the reverse process by converting encoded sequences back into their original characters. This ensures that text containing spaces, symbols, and Unicode characters can be accurately restored after being transmitted through web addresses or network requests.
