Percent-encode URLs and query parameters for safe HTTP transmission, or decode encoded strings back to readable text. Handles Unicode and reserved chars.
URL Encoder & Decoder is a browser-based tool on 24Toolkit. Percent-encode URLs and query parameters for safe HTTP transmission, or decode encoded strings back to readable text. Handles Unicode and reserved chars. Our URL Encoder/Decoder encodes and decodes URLs and text for safe transmission in web applications. URL encoding converts special characters (spaces, unicode) to percent-encoded format (e.g., %20 for space). Essential for query strings, API parameters, and any URL containing special characters. All encoding and decoding happens locally in your browser. Encoding and decoding use the browser's built-in encodeURIComponent and decodeURIComponent functions, so your URLs and query strings are processed locally. Use Encode for preparing URLs or Decode for reading encoded strings. URL Encoder & Decoder is a browser-based workflow on 24Toolkit at /url-encoder-decoder for users who need fast, private results without installing software. Percent-encode URLs and query parameters for safe HTTP transmission, or decode encoded strings back to readable text. Handles Unicode and reserved chars. The page is designed for direct use in modern browsers

FAQ
When should I encode a URL?
Encode when your URL contains spaces, special characters (+, &, =), or non-ASCII characters (Arabic, emoji). Encoding ensures the URL works correctly in browsers and APIs.
Does my data leave the browser during encoding?
No. Encoding and decoding use the browser's built-in encodeURIComponent and decodeURIComponent functions. Your URLs and query strings are processed entirely in client-side JavaScript.
What characters get encoded?
Spaces become %20, & becomes %26, = becomes %3D, and unicode characters become percent-encoded UTF-8 sequences.
