URL Encoder/Decoder

URLs can safely contain only a limited set of ASCII characters. Spaces, ampersands, hash symbols, question marks, accented letters, and non-Latin characters like Chinese, Arabic, or Korean text must be percent-encoded before use in a URL or query string. This encoding converts each unsafe character to a percent sign followed by its two-digit hexadecimal code — for example, a space becomes %20 and an ampersand becomes %26. This URL encoder converts any text to its percent-encoded form for safe use in GET parameters, REST API calls, and form submissions, and also decodes encoded URLs back to their original readable form. A common situation where this tool proves essential is building query strings for API requests. If you are calling a search endpoint and your query contains the phrase "coffee & tea" or a filter like "price>50", those characters must be encoded before being appended to the URL, otherwise the server will misinterpret the request or return an error. Another everyday use case is sharing links that include non-English text — a travel blogger linking to a page titled in Japanese, or a developer embedding a French city name into a mapping API call, must encode that text so it survives being copied and transmitted across systems that only handle ASCII. A third scenario is debugging: when you receive a URL from a log file or error report packed with percent sequences, pasting it here instantly decodes it back to human-readable text so you can understand exactly what was requested. Developers integrating third-party REST APIs, QA engineers inspecting network traffic, and data engineers constructing webhook URLs are among those who rely on this tool most heavily. It is equally useful for front-end developers assembling URLs dynamically and for anyone crafting links by hand in configuration files. All encoding and decoding happens directly in your browser — no text is sent to any server, so sensitive query parameters, tokens, or personal data remain completely private.
