URL Encode

Have you ever seen strange symbols in a web address? These are often the result of URL encoding. In this guide, we will explore what URL encoding is and why it is crucial for the web.

What is URL Encoding?

URL encoding is a process. It converts special characters into a format that can be transmitted over the Internet. This makes URLs more reliable and easier to work with.

Why Do We Need Url Encoding?

Here are some reasons why URL encoding is necessary:

• Special characters can confuse web browsers.
• Some characters have special meanings in URLs.
• Encoding helps maintain data integrity.
• It allows safe transmission of user data.

How Does URL Encoding Work?

URL encoding replaces unsafe characters with a "%" followed by two hexadecimal digits. For example:

• Space becomes %20
• Exclamation mark (!) becomes %21
• At symbol (@) becomes %40

Let’s take a closer look at some characters and their encoded forms:

Character	Encoded Form
	%20
!	%21
#	%23
$	%24
&	%26
'	%27
(	%28
)	%29
	%2A
+	%2B
,	%2C
/	%2F
:	%3A
;	%3B
=	%3D
?	%3F
@	%40

Common Use Cases for URL Encoding

URL encoding appears in many situations. Here are some common use cases:

• When users submit forms online.

Imagine a user wants to search for "best pizza in New York!". The search query might look like this:

best pizza in New York!

After URL encoding, it becomes:

best%20pizza%20in%20New%20York%21

The encoded URL could look like this:

https://example.com/search?q=best%20pizza%20in%20New%20York%21
