About Escape helper
Escape Helper sanitizes and encodes raw strings for safe insertion into HTML, JavaScript, SQL, URL query strings, and regular expressions. Protect your frontend and backend applications from injection vulnerabilities by verifying string escaping locally in your browser.
When to use Escape helper
- Escape user input before rendering inside HTML templates to prevent Cross-Site Scripting (XSS)
- Prepare JSON and JavaScript strings with escaped quotes, backslashes, and control characters
- Format URL query parameters with RFC 3986 percent-encoding
- Sanitize string literals before constructing database queries or regex patterns
How it works
Paste your raw text into the editor. The tool applies standard entity and character replacement tables (e.g. & to &, < to <, " to ", and regex metacharacter prefixing) and outputs the escaped representation instantly without server transmission.
Example
HTML Entity Escaping
Input:
<script>alert("Nadhebe & security");</script>Output:
<script>alert("Nadhebe & security");</script>Privacy & Security Guarantee
Escape helper processes all data locally inside your web browser. No input text, files, credentials, or outputs are ever transmitted to remote servers, logged to analytics databases, or retained across sessions.
