HTML Entity Encode/Decode: A Complete Guide
HTML entities are special characters used in HTML, which have a specific meaning in the markup language. When we need to use characters that have special meaning in HTML, we must use the appropriate HTML entity instead of the character itself. For example, if we need to display the less than sign (<) in our HTML document, we must use the HTML entity < instead of the character itself.
Encoding and decoding HTML entities can be a time-consuming and tedious task, especially if we have a lot of text to work with. That's where the online tool HTML Entity Encode/Decode comes in handy. In this article, we will take a closer look at how to use this tool to encode and decode HTML entities.

What are HTML Entities?
HTML entities are special characters used in HTML to represent reserved characters or characters that cannot be entered directly into a document.
For example, the less than sign (<) and greater than sign (>) are reserved characters in HTML and cannot be used directly in a document. Instead, we must use the HTML entities < and > to represent these characters.
There are also other characters that cannot be entered directly into an HTML document, such as non-breaking spaces and special characters like copyright symbols. These characters must also be represented using HTML entities.
Why do we need to Encode and Decode HTML Entities?
Encoding and decoding HTML entities is necessary to ensure that all special characters in a document are displayed correctly in the browser. If we do not use the appropriate HTML entity to represent a reserved character, the browser may interpret it as an instruction or command, which can lead to unexpected results.
For example, if we use the less than sign (<) without encoding it as <, the browser may interpret it as the beginning of an HTML tag, which can cause problems with the layout and formatting of the document.
On the other hand, decoding HTML entities is necessary to convert the special characters back to their original form, which is useful when we need to edit or modify an HTML document. If we leave the HTML entities in the document, it can be difficult to read and modify the text.
