About URL Encoding/Decoding

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.

URL encoding replaces unsafe characters with a "%" followed by two hexadecimal digits (percent-encoding).

URL decoding is the reverse process, converting encoded characters back to their original form.

Frequently Asked Questions
