Enter the text that you wish to encode or decode:
The URL Encoder / Decoder converts text into a URL-safe format and converts encoded URLs back into readable text. Paste your string, choose encode or decode, and get the result instantly.
It is a handy utility for developers, marketers, and SEO professionals who work with links, query strings, and tracking parameters.
URLs can safely contain only a limited set of characters. Spaces, symbols, and non-English characters must be converted to percent-encoded form, such as %20 for a space.
URL encoding replaces unsafe characters with a percent sign followed by two hexadecimal digits, and decoding reverses the process.
Unencoded characters can break links, corrupt query strings, or be interpreted incorrectly by servers and browsers. Proper encoding ensures data reaches its destination intact.
Each unsafe character is converted to its byte value and written as a percent sign followed by a two-digit hexadecimal number. Non-ASCII characters are first converted to UTF-8 bytes.
Be careful not to encode a full URL twice, because double encoding turns % signs into %25 and can break the link.
| Character | Encoded |
|---|---|
| Space | %20 |
| & | %26 |
| = | %3D |
| ? | %3F |
| / | %2F |
| # | %23 |
| @ | %40 |

It is a method of converting unsafe characters in a URL into percent-encoded form so they can be transmitted safely.
%20 is the encoded form of a space character.
Usually you should encode individual values, such as query parameters, and leave the structural characters like :// and / intact.
It happens when already encoded text is encoded again, turning % into %25 and breaking the link.
No. Encoding only changes the format and offers no security or privacy protection.
