URL Encoder/Decoder
Encode and decode URL strings for safe transmission
About This Tool
URL encoding converts characters into a format that can be transmitted over the Internet. URLs can only be sent over the Internet using the ASCII character set.
This tool uses encodeURIComponent and decodeURIComponent functions to encode and decode URLs locally in your browser. Your data is never sent to any server.
Frequently Asked Questions
What is URL encoding?
URL encoding replaces unsafe ASCII characters with a '%' followed by two hexadecimal digits. For example, a space becomes %20, and an ampersand becomes %26.
When should I use URL encoding?
Use URL encoding when you need to include special characters, spaces, or non-ASCII characters in a URL parameter or path. This ensures the URL is valid and works correctly.
What's the difference between encodeURI and encodeURIComponent?
encodeURI is for encoding a complete URL, keeping protocol and domain characters. encodeURIComponent is for encoding URL parameters, encoding all special characters.
