The URL Encoder Decoder helps developers and SEO analysts format strings for use in URL query strings. Web links must use specific ASCII characters. Special characters (like spaces, ampersands, or brackets) have specific meanings or are invalid in URLs. Percent encoding replaces these characters with a '%' followed by hexadecimal representations.
Processing is done entirely within your local browser, keeping your URLs secure.
Encode or Decode a URL
How to Use
Paste URL String
Paste the raw text or percent-encoded link into the main input editor.
Run Action
Click 'Encode URL' to make text safe for browsers, or click 'Decode URL' to translate code back to plain text.
Copy and Use
Review the formatted output in the text box and copy it to your clipboard.
Why Use This Tool?
Prevent Broken Links: Encode special parameters so they don't break browsers or CMS systems.
Translate Messy URLs: Decode percent-encoded parameters to read where a redirect link points.
100% Client-Side: Safely encode proprietary query links locally in your browser.
Practical Example
A marketer wants to send a URL with a query parameter: 'mysite.com/search?q=shoes & boots'. The space and ampersand are unsafe. They paste it, select Encode, and get 'mysite.com/search?q=shoes%20%26%20boots' which is safe for email and browsers.
Limitations
Standard percent encoding (RFC 3986). Does not shorten URLs; it only translates characters.
