URL Encoder / Decoder
Encode or decode URLs and special characters instantly. Handles spaces, unicode, query parameters, and all special characters.
What Is URL Encoding?
URL encoding (also called percent-encoding) converts special characters into a format that can be safely transmitted in a URL. For example, spaces become %20, ampersands become %26, and non-ASCII characters get converted to their UTF-8 byte representation. This is required for query parameters, form data, and any URL that contains special characters.
When Do You Need URL Encoding?
You need URL encoding when passing data in query strings, building API requests, handling redirect URLs, or working with internationalized domain names. Most programming languages have built-in functions (encodeURIComponent in JavaScript, urllib.parse.quote in Python), but this tool gives you instant results without writing code.
