What is URL encoding and Why to use URL Encoder and Decoder Tool by SEO Tools Kit?

URL encoder means encoding certain characters in the URL. It is a two-step process:

The string character is encoded into a sequence of bytes.Then, each byte that is not an ASCII letter or a digit is converted to a hexadecimal value of the byte. Example: The string "François", would be encoded "Fran%C3%A7ois." We can see that this can make a URL a bit longer than before. But the intention of using this technique is that browsers only need to display the decoded form, and many protocols can send UTF-8 without the %HH escaping. URL Encoder/ Decoder tool by SEO Tools Kit is the online tool used to either encode or decode a string of text.

What are reverse characters?

Reserved characters are special characters with a special purpose in a given context. A URL system indicates that if the same character is used for different purposes, then the character has to be percent-encoded. The process includes translating the character into its equivalent ASCII value followed by representing the resulting value using two hexadecimal digits. Hence, to encode any URL, use the URL Encoder/ Decoder Tool by SEO Tools Kit.
