About HTML Entity Encoder/Decoder
Speak the Browser's Language
HTML reserved characters are the bane of every web developer's existence. If you try to write "<div>" on a website, the browser thinks you are starting a code block. To display it as text, you must encode it as <div>.
Our HTML Entity Encoder/Decoder automates this tedious process, ensuring your code snippets are safe to display and your special characters render correctly.
What gets Encoded?
- Reserved Characters:
<becomes<,>becomes>,&becomes&. - Invisible Characters: Non-breaking spaces become
. - Symbols:
©becomes©,™becomes™.
Security: XSS Prevention
Encoding is the first line of defense against Cross-Site Scripting (XSS) attacks. If you accept user input and display it without encoding, a hacker can inject malicious JavaScript (<script>alert(1)</script>). By running it through this tool (or a similar function in your code), you neutralize the script, turning it into harmless text <script>....
