Frequently Asked Questions
What is an HTML entity?
An HTML entity is a string of text (starting with an ampersand and ending with a semicolon) used to display reserved characters that the browser would normally interpret as HTML code, such as displaying "<" instead of starting an actual HTML tag.
Why do I need to encode HTML entities?
Encoding ensures that the browser displays your text visually rather than trying to execute it as code. This is crucial for displaying code blocks on websites and forms a basic defense against Cross-Site Scripting (XSS) attacks.
Is my text or code sent to a server?
No. This tool operates entirely in your web browser. All encoding and decoding logic is processed locally, meaning your data is never transmitted to an external server.
Which characters are encoded by this tool?
For maximum security and speed, this tool encodes the standard reserved characters: ampersands (&), less-than signs (<), greater-than signs (>), double quotes ("), and single quotes (').
Can I decode entities back into standard text?
Yes, this is a two-way tool. If you have an exported database string or a text block full of entities, simply paste it in and click "Decode" to restore it to plain readable text.
Do I need to create an account?
Not at all. This utility is 100% free for developers and content creators with no account, login, or subscription required.
