What is the HTML Entity Encoder?
The HTML Entity Encoder replaces the special characters that HTML treats as markup with named or numeric entity equivalents. That way user-generated text can be safely embedded inside HTML without breaking the page or opening cross-site scripting holes.
It is essential for anyone who takes untrusted text and drops it inside an HTML template.
Who is the HTML Entity Encoder for?
Backend developers rendering user input, security engineers auditing templates, technical writers embedding code examples in blog posts, and email marketers pasting text into HTML templates.
Why use the HTML Entity Encoder?
- Escapes the five HTML-critical characters by default.
- Optional aggressive mode for non-ASCII characters.
- Instant preview.
- Prevents accidental XSS via untrusted input.
- Runs entirely in the browser.
When should I use the HTML Entity Encoder?
- Escaping user input before rendering it inside HTML.
- Embedding code examples inside a blog post.
- Preparing email templates that display raw text.
- Fixing text that broke a page because of an unescaped &.
- Preparing safe copy for a template engine that does not auto-escape.
Is the HTML Entity Encoder safe and private?
Yes. This tool runs entirely inside your browser - your text is never uploaded, stored on our servers or shared with third parties. You can even disconnect from the internet after the page loads and it will keep working. That makes it safe for confidential notes, drafts, private messages and unpublished work.
How do I get the best results from the HTML Entity Encoder?
- Always escape untrusted input before injecting it into HTML.
- Prefer entity encoding over stripping tags when you want to preserve the text.
- Use aggressive mode for maximum compatibility with old email clients.
- Do not rely on encoding alone - pair it with a strong Content-Security-Policy.
