HTML Entity Sanitizer
Securely escape and unescape HTML strings bidirectionally without DOM injection.
Securely escape and unescape HTML strings bidirectionally without DOM injection.
Many online HTML escaping tools use a dangerous method known as DOM injection (element.innerHTML = text) to parse entities. If a malicious script is pasted, the browser might accidentally execute it. Layerbit mitigates this entirely.
Sanitize raw user input from forms, comments, and text areas before storing it in your database to prevent Cross-Site Scripting (XSS) injection attacks across your application.
Safely encode complex HTML strings so they can be embedded directly within JSON API payloads without breaking string boundaries or disrupting downstream parsers.
Convert raw HTML elements into secure, escaped entities so they render visibly as code blocks in the DOM rather than being interpreted and executed by the browser engine.

If an online tool sets your pasted text to element.innerHTML in order to read the browser's parsed entities, any valid <script> tags or inline event handlers (like onload) within your text can immediately execute in the browser. Layerbit operates strictly on regex string replacement to prevent arbitrary execution.
The matrix targets the most critical control characters utilized in HTML rendering and script execution: Ampersands (&), less than/greater than symbols (< >), double/single quotes (" '), forward slashes (/), backticks (`), and equals signs (=).
No. While this tool is perfect for ad-hoc preparation and debugging, enterprise applications should never trust client-side input exclusively. You must always sanitize strings on your backend server before executing SQL inserts or NoSQL document updates.
