URL Encoder/Decoder
Encode or decode URLs for safe web transmission
About URL Encoding
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. Since URLs often contain characters outside the ASCII set, they have to be converted into a valid ASCII format.
URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits corresponding to the character values in the ISO-8859-1 character set. Spaces are replaced with a plus (+) sign or with %20.
Common use cases include:
- Passing parameters in URLs that contain special characters
- Creating SEO-friendly URLs (though modern frameworks often handle this automatically)
- Encoding data for form submissions
- Handling international characters in URLs
