About HTML Encoding
HTML encoding is the process of converting special characters to their corresponding HTML entities. This is important for several reasons:
- Displaying special characters: Some characters have special meaning in HTML (like < and >) and need to be encoded to display properly.
- Preventing XSS attacks: Encoding user input helps prevent cross-site scripting (XSS) attacks by ensuring that browser doesn’t interpret the input as executable code.
- Character set compatibility: HTML entities ensure that characters display correctly regardless of the document’s character encoding.
Types of HTML Entities
HTML entities can be represented in two ways:
- Named entities: Use a name to represent the character, like < for <
- Numeric entities: Use the character’s Unicode code point, like < for <
This tool supports both encoding and decoding of HTML entities, making it easy to convert between regular text and HTML-safe text.

Why You Need an HTML Encode/Decode Tool
Have you ever tried to display a less-than sign (<) on your webpage, only to have it break your entire layout? This common frustration highlights a critical need in web development: handling special characters safely. An HTML Encode/Decode Tool is the essential solution for developers, content creators, and SEO specialists. It ensures that your text displays correctly and your website remains secure from malicious attacks. This guide will explain how HTML encoding and decoding works and why our free, instant tool is indispensable for your workflow.
What is HTML Encoding?
HTML encoding converts reserved and special characters into their corresponding HTML entities. These entities are a string of text that the browser interprets and displays as the desired symbol.
This process is crucial because characters like <, >, and & have specific meanings in HTML syntax. If you want to display them as text, you must encode them.
Example of Encoding:
- Original Text:
"The price is < $100 & > $50." - After HTML Encoding:
"The price is < $100 & > $50."
The encoded version ensures the browser displays the symbols correctly instead of treating them as code.
What is HTML Decoding?
HTML decoding is the reverse process. It converts HTML entities back into their original, human-readable characters. This is vital when you have encoded text that you need to edit or understand at a glance.
Example of Decoding:
- Encoded Text:
"John & Jane's website" - After HTML Decoding:
"John & Jane's website"
Decoding makes the text editable and readable again, restoring the original symbols.
Top 5 Reasons to Use an HTML Encoder/Decoder
- Prevent Code Injection & XSS Attacks
Encoding user-generated content before displaying it on your site is a primary defense against Cross-Site Scripting (XSS) attacks. It neutralizes potentially harmful scripts by converting them into harmless text. - Ensure Content Displays Correctly
Avoid layout breaks and display errors by encoding special characters. This guarantees that your content looks exactly as you intended, from mathematical symbols to quotations. - Improve Code Validation and Cleanliness
Using encoded entities helps your HTML code pass validation checks. It creates cleaner, more standards-compliant markup that works reliably across all browsers. - Simplify Content Management
When you need to copy text from a webpage into a code editor or database, decoding it first removes the entities, giving you clean, editable text. - Enhance Data Integrity
When transferring data between a server and a client, encoding ensures that the structure and meaning of the data are preserved without interfering with the DOM.
Common HTML Entities You Should Know
Understanding common entities helps you debug and write better code.
| Character | Entity Name | Entity Number | Purpose |
|---|---|---|---|
| < | < | < | Less-than sign |
| > | > | > | Greater-than sign |
| & | & | & | Ampersand |
| “ | " | " | Double quotation mark |
| ‘ | ' | ' | Apostrophe/single quote |
| © | © | © | Copyright symbol |
