URL Encoder and Decoder
Encode text for use in URLs or decode existing URL encoded strings directly in your browser. This tool uses the standard encodeURIComponent and decodeURIComponent functions provided by modern browsers.
URL encoding is useful when working with query strings, redirects, API calls and links that contain special characters such as spaces, ampersands or unicode. No data is sent to any server, all processing happens locally.
How to use the URL encoder
Type or paste text into the input box and choose Encode to produce a URL safe version where spaces and special characters are replaced with escape sequences. Use Decode when you have an existing URL encoded string and need to turn it back into readable text.
Common questions
What characters does URL encoding affect?
URL encoding replaces characters that are not safe in URLs such as spaces, quotes and some symbols with percent encoded values. For example, a space becomes %20.
When should I encode URLs?
You should encode values when building query strings, path parameters or redirect URLs that contain user input, special characters or unicode. This prevents broken links and avoids parsing issues.
Is my input sent to a server?
No. All encoding and decoding is done locally in your browser using built in JavaScript functions. The text you paste is not uploaded or stored.
