Encode or decode URL strings

About URL Encoder/Decoder

URL encoding (also called percent-encoding) converts special characters in URLs into a format that can be safely transmitted over the internet. Characters like spaces, ampersands, question marks, and non-ASCII characters must be encoded to ensure URLs function correctly.

Frequently Asked Questions

When do I need to URL-encode something? +
When a value goes into a URL (path, query string, fragment) and contains spaces, special characters (&, =, #, /), or non-ASCII characters. Encoding ensures the URL stays valid and the value reaches the server intact.
What is the difference between encodeURIComponent and encodeURI? +
encodeURIComponent encodes more aggressively and is right for values inside a query string. encodeURI preserves URL structural characters like // and & and is for whole URLs. Our tool uses encodeURIComponent, the safer default.
Can I decode URLs from logs or analytics? +
Yes. Paste the encoded string and get back the original content — useful for reading query strings containing search terms or user input.
Is my URL sent anywhere? +
No. Encoding is done locally in your browser. The tool does not log or transmit anything.
Why does my URL have %20 or + in it? +
Both represent space. %20 is standard percent-encoding and works everywhere. Plus signs appear in application/x-www-form-urlencoded form bodies. Our tool decodes both.
