HTML Entity Encoder
Escape text so it displays safely inside HTML. Encode just the five characters that break markup (& < > " '), every non-ASCII character, or everything, and choose named (©), decimal (©) or hex (©) entities.
Paste text or HTML, choose which characters to encode and the entity style, and copy the result. Encoding & < > " and ' is what prevents user text from breaking your page or injecting script into HTML text and quoted attributes.

When to escape HTML
Whenever you insert text into HTML that you didn't write — comments, names, search terms — escape it, or an attacker's <script> becomes part of your page (XSS). Showing code samples on a web page also requires escaping < and &.
Different contexts need different escaping: HTML entity encoding is right for element text and quoted attributes, but not inside <script>, style blocks or URLs.
Encoding is not encryption
Encoding changes how data is written so it can travel safely through URLs, HTML or text-only systems. It uses no key, so anyone can decode it instantly. Never use Base64, URL or HTML encoding to hide passwords or secrets — use encryption, or a password hash like bcrypt.
Frequently Asked Questions
Named or numeric entities?
Both work in every browser. Named entities are easier to read; numeric ones work for every Unicode character, including those without a name.
Is my code or data uploaded?
No. Everything runs in your browser; nothing you paste is sent to a server or stored.
