How to use URL Encoder

Paste any text or URL containing special characters and click Encode. The tool converts characters to their percent-encoded equivalents, making them safe for use in query strings, path segments, and fragment identifiers.

What is URL Encoding?

URL encoding, also known as percent-encoding, converts characters into a format that can be transmitted over the Internet. URLs can only be sent using the ASCII character set. Special characters that are not ASCII, or that have special meaning in URLs, must be encoded.

For example, a space character is encoded as %20, and an ampersand (&) is encoded as %26. This ensures URLs remain valid and properly interpreted by browsers and servers.

Characters that Need Encoding

Reserved characters - ! # $ % & ' ( ) * + , / : ; = ? @ [ ]
Non-ASCII characters - Characters beyond ASCII range (128+)
Space - Encoded as %20 or +
Control characters - Characters with special meaning in URLs

FAQ

What's the difference between encodeURI and encodeURIComponent?encodeURI doesn't encode characters that are part of a complete URL, while encodeURIComponent encodes everything except alphanumeric characters.

Why do I need to encode URLs?URLs have strict syntax rules. Special characters can break URL parsing or change the URL's meaning entirely.

Is encoding the same as encryption?No, encoded URLs are easily decoded. Don't use URL encoding for security purposes.
