HTML Entity Encoder / Decoder
Encode special characters into HTML entities and decode entities back into characters. No signup. Ideal for web developers escaping text for safe display in HTML.
This HTML entity encoder and decoder escapes special characters into HTML entities, and decodes entities back into characters, directly in your browser. Paste your text and encode or decode it. No account, no install, so web developers can escape text for safe HTML display on any device in seconds.
How to Encode and Decode HTML Entities Step by Step
- Paste your text. Drop the text you want to encode or decode into the input. For encoding, this is text with special characters; for decoding, text with HTML entities.
- Choose encode or decode. Select whether you want to encode the text into HTML entities, or decode existing entities back into their characters.
- Process the text. The tool encodes the special characters into their HTML entities, or decodes the entities back into the characters they represent.
- Read the result. See the encoded text, with special characters replaced by entities, or the decoded text, with entities turned back into characters.
- Copy and use it. Copy the result and use it in your HTML, or wherever you need the escaped or unescaped text, for safe and correct display.
What HTML Entities Are and Why They Matter
In HTML, certain characters have special meaning, such as the characters that denote tags. If you want to display these characters as literal text rather than have the browser interpret them as HTML, you must escape them using HTML entities, which are special codes that represent the characters. HTML entity encoding replaces such special characters with their entity codes, so they display correctly as text.
The reason this matters is that unescaped special characters can break the HTML or be misinterpreted. If a character that HTML treats specially appears unescaped in content, the browser may interpret it as markup rather than displaying it, causing display problems or, in some contexts, security issues. Escaping these characters into entities ensures they are displayed as intended, as literal text, rather than being interpreted by the browser.
Encoding and decoding are the two directions of this process. Encoding turns special characters into their HTML entities, for safe inclusion in HTML. Decoding does the reverse, turning entities back into the characters they represent, useful when you have encoded text and want to recover the original characters. A tool that does both lets you escape text for HTML and unescape it as needed, handling entities in both directions.
HTML entity encoding is used by web developers whenever text containing special characters must be safely displayed in HTML. Content that includes characters HTML treats specially needs escaping so it shows correctly and does not break the page. Decoding is useful for reading or processing already encoded text. Because doing this by hand is tedious and error prone, an encoder and decoder makes handling HTML entities quick and reliable.
Encoding Versus Decoding Entities
| Aspect | Encoding | Decoding |
|---|---|---|
| Direction | Characters to entities | Entities to characters |
| Purpose | Escape for safe HTML display | Recover original characters |
| Used when | Including special characters in HTML | Reading encoded text |
| Result | Text safe for HTML | The original characters |

Frequently Asked Questions
How do I encode and decode HTML entities?
Paste your text into the input, choose whether to encode or decode, and the tool encodes the special characters into their HTML entities, or decodes existing entities back into the characters they represent. For encoding, it replaces characters that HTML treats specially with their entity codes, so they display safely as literal text. For decoding, it turns entities back into characters, recovering the original text. Copy the result and use it in your HTML or wherever needed. This handles HTML entities in both directions, escaping text for safe display and unescaping it as required.
What are HTML entities?
HTML entities are special codes that represent characters in HTML. In HTML, certain characters have special meaning, such as those that denote tags. To display these characters as literal text rather than have the browser interpret them as HTML markup, you escape them using HTML entities, which are codes standing for the characters. When the browser encounters an entity, it displays the corresponding character rather than interpreting it as markup. So HTML entities let you safely include special characters in HTML content, ensuring they show correctly as text instead of breaking the page or being misinterpreted by the browser.
Why do special characters need escaping in HTML?
Because certain characters have special meaning in HTML, such as those used to denote tags, so if they appear unescaped in content, the browser may interpret them as markup rather than displaying them as text. This can cause display problems, break the HTML structure, or in some contexts create security issues. Escaping these characters into HTML entities ensures they are displayed as intended, as literal text, rather than being interpreted by the browser. So escaping is necessary whenever you want to show characters that HTML treats specially as actual text within your web content.
What is the difference between encoding and decoding?
Encoding and decoding are the two directions of handling HTML entities. Encoding turns special characters into their HTML entities, escaping them for safe inclusion and display in HTML, so they show as literal text rather than being interpreted as markup. Decoding does the reverse, turning HTML entities back into the characters they represent, which is useful when you have encoded text and want to recover the original characters, for reading or processing. So encoding escapes text for HTML, while decoding unescapes it back to the original. A tool that does both lets you handle entities in whichever direction you need.
When should I encode text for HTML?
You should encode text for HTML whenever it contains characters that HTML treats specially and you want them displayed as literal text rather than interpreted as markup. This is common when displaying code samples or symbols, and when including content, such as user provided or dynamic content, that may contain special characters, since escaping it helps ensure it displays correctly and does not break the page. Encoding such text into HTML entities before including it in your HTML ensures the special characters show as intended and the page displays and behaves correctly, which is good practice for safe display of content with special characters.
What is double encoding and why avoid it?
Double encoding is when you encode text that is already encoded, which turns the entity codes themselves into entities. The result is that the entity codes display as literal text rather than the intended characters, since they have been escaped an extra time. This is a common mistake that causes text to show the raw entity codes instead of the characters. To avoid it, encode text only once, and if you need to reverse an encoding, decode it rather than encoding again. Being clear about whether text is already encoded prevents accidentally double encoding it and getting incorrect display.
Is decoding HTML entities safe?
Decoding turns HTML entities back into the special characters they represent, which is useful when you want the original, unescaped characters, for reading or processing text. However, you should only decode when you actually want those original characters, not text that needs to stay encoded for safe HTML display. Decoding text that should remain encoded turns the entities back into special characters that could then break the HTML or be misinterpreted if placed back into a page. So decoding itself is a normal operation, but use it appropriately: to recover original text, while keeping text encoded where it must remain safe for HTML.
Is the HTML entity encoder free?
Yes, it is completely free with no account and no usage limit. You can encode and decode as much text as you like, as often as you like, at no cost. It runs entirely in your browser on any device, so your text is processed locally and there is nothing to download or install, and the encoded or decoded result appears instantly whenever you process your text, helping web developers escape text for safe HTML display and unescape it as needed.
