How to Use URL Encoder/Decoder

Paste the text or URL you want to convert into the textarea, then use the Encode/Decode toggle to select the direction of conversion. In Encode mode, the tool converts special and reserved characters — spaces, ampersands, question marks, and non-ASCII characters — into their percent-encoded equivalents using `encodeURIComponent`, producing a string that's safe to use as a query parameter or embed inside another URL. In Decode mode, paste a percent-encoded string, such as one copied from a browser address bar or server log, and the tool converts it back into readable, human-friendly text using `decodeURIComponent`. The conversion happens instantly as you type or paste, with no need to click a separate 'convert' button, and the result appears directly below the input. Once you have your encoded or decoded string, use the copy button to grab it immediately and paste it wherever you need it, whether that's directly into a URL bar, an API request, or a piece of code that builds links dynamically. Because this tool relies entirely on the browser's built-in, standards-compliant URI encoding functions, the output matches exactly what browsers and web servers expect, avoiding subtle mismatches that can happen with hand-rolled encoding logic.

Why Use Our URL Encoder/Decoder?

URLs can only safely contain a limited set of characters, so anything else — spaces, special symbols, or characters from non-Latin alphabets — needs to be percent-encoded before it can be reliably used in a link or query string. Getting this wrong leads to broken links or misinterpreted parameters that can be maddening to debug. Our URL Encoder/Decoder uses the browser's native, standards-compliant encoding functions, so the results are guaranteed to match what real browsers and servers expect, unlike some manual or approximate encoding methods. It's especially useful for developers building URLs dynamically, debugging a broken redirect, or decoding a long tracking URL to see what parameters it actually contains. Everything happens instantly in your browser with no server round-trip, so there's no lag even for long strings, and no risk of a URL containing sensitive tokens or session data being logged externally. It's free, always available, and faster than opening a code editor just to test an encoding function.
