URL Encoder/Decoder
Encode or decode URLs and query strings
Read the full guideDifference between encode types:
- URI Component: Encodes all special characters including : / ? # @ ! $ & ' ( ) * + , ; =
- Full URI: Preserves URL structure characters like : / ? # but encodes spaces and other unsafe characters
Safely transmit data via URLs. Our URL Encoder/Decoder helps you convert reserved characters into percent-encoded strings to prevent broken links and ensure data integrity across web protocols.
URL Encoding, also known as Percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL must be replaced by a '%' followed by two hexadecimal digits. For example, a space becomes '%20'.
Query Parameters
When passing data like search queries or email addresses in a URL string.
Deep Linking
Ensuring that special characters in a path do not terminate the URL prematurely.
API Authentication
Encoding Base64 tokens or signatures that might contain '+' or '/' characters.
The tool uses standard JavaScript `encodeURIComponent` and `decodeURIComponent` logic to ensure compliance with RFC 3986. 'URI Component' is used for query values, while 'Full URI' is used for entire addresses.
| Character | encodeURI | encodeURIComponent |
| / | Kept (/ ) | Encoded (%2F) |
| ? | Kept (? ) | Encoded (%3F) |
| & | Kept (& ) | Encoded (%26) |
Fully compatible with all mobile and desktop browsers. Perfect for quick use during web development.
