HTML escape online

Escape string markup to safe entities in your browser

HTML escape online — paste raw text or markup and convert angle brackets, ampersands, and quotes into entities like < and '. Built for developers who need a fast escapehtml workflow without installing desktop utilities.

Escaping runs entirely in your browser — nothing uploads. Use our HTML Unescape tool to reverse entities back to readable text.

Basic HTML escape (conceptual)

Replace & with &amp; first, then < > " and '. Full mode additionally maps code points outside printable ASCII to &#decimal; entities.

text.replace(/&/g,"&amp;").replace(/</g,"&lt;").replace(/>/g,"&gt;")

Escape example

Input: <a href="/search?q=1&2">Link</a> — basic output escapes brackets, ampersand, and quotes so the string is safe inside an HTML text node.

Full mode encodes emoji and accented letters as numeric entities, producing longer but ASCII-only output.

Complete guide to escaping HTML online

What HTML escape does

HTML escape converts characters that browsers treat as markup into entity form so text displays literally instead of executing as tags. When you escape html online, angle brackets become &lt; and &gt;, ampersands become &amp;, and quotes become &quot; or &#39;.

This is not encryption — anyone can unescape entities — so treat escaping as a presentation and safety layer for text contexts, not a way to hide secrets.

Basic mode escapes the five characters that matter most in HTML text nodes. Full mode also emits numeric entities for non-ASCII code points, useful when you need predictable ASCII-only wire format.

Escaped output grows longer than the original. A short escape string with emoji may expand noticeably in full mode because each non-ASCII character becomes a &#...; sequence.

How to escape HTML characters online

Type or paste text into the input panel. Escaped output updates live as you edit. The snippet <p>Hello</p> becomes &lt;p&gt;Hello&lt;/p&gt; in basic mode.

Choose basic when you only need standard html escape characters for blog code samples or template placeholders. Choose full when downstream systems reject raw Unicode or when you want every special symbol encoded numerically.

Copy the result with one click or download as a .txt file. For round-trip checks, paste the output into our HTML Unescape tool and confirm the original text returns.

Import small .txt, .html, or .xml files when you need to escape a file snippet without retyping. Clear the fields when finished on shared machines.

Escape HTML in JavaScript, Python, and frameworks

Escape html javascript patterns often map < > & " ' manually or call a library. Compare this tool's output against your escape in javascript helpers when debugging XSS fixes or email templates.

Python html escape typically uses html.escape() from the standard library — the same five characters in basic mode. Teams comparing python escaped output against browser tools should match basic level first.

Angular escape html and similar framework bindings auto-escape text interpolations; use this page when crafting static HTML emails, documentation snippets, or CMS fields that do not pass through a template engine.

WordPress escape html, Magento escapehtml, and Blazor escape helpers each wrap server-side logic. This client-side escape tool lets you preview entity output before pasting into a theme, plugin, or Razor partial.

When to escape a string for HTML

User-generated comments and forum posts: escape before inserting into HTML text nodes so <script> appears as literal text on screen.

Code samples in blog posts: escape angle brackets so themes and WYSIWYG editors do not swallow sample tags.

Email and notification templates: many clients expect entity-safe attribute values; escape quotes inside title and alt attributes.

API debugging: when a JSON field contains HTML fragments, escape here to see the safe form your renderer should emit.

Escape vs other escaping layers

Escape special characters javascript inside a <script> block requires JavaScript string rules — backslashes and quotes — not HTML entities alone. JSON embedded in pages needs JSON.stringify.

URL parameters use percent encoding — see our URL Encoder. Regex metacharacters need escape in regex patterns, not html escape.

Solr escape special characters, MongoDB escape special characters, Elasticsearch escape special characters, and ServiceNow escape special characters each follow query-language rules unrelated to HTML entities — use the right tool for each stack.

GitHub Actions escape quotes and escape character workflows address YAML and shell contexts, not markup. ANSI color codes python and f string escape bracket topics are also separate from HTML.

Privacy and related tools

Escaping runs locally in your browser. Customer names, template bodies, and internal error messages never upload to a server. Clear the textarea when finished on shared computers.

Pair with our HTML Unescape tool for reverse conversion. Use the URL Encoder for address layers and Base64 tools when payloads are transport-encoded rather than markup-escaped.

Escaping is one layer of XSS prevention; content security policy and sanitizers still matter when you publish rich HTML from untrusted sources.

Detailed guide

Escaping code for a documentation page

Paste your sample snippet, copy the escaped output, and insert it inside a <pre> or code block in your CMS. Confirm the page renders literal angle brackets.

If your syntax highlighter expects raw source, escape only the wrapper HTML — not the code block content the highlighter reads.

Matching python html escape output

Run html.escape(your_text) in Python and compare against basic mode here. Mismatches on quotes usually mean different quote-escaping options.

Store the escape output in a test fixture so CI asserts the exact entity form your API returns.

Common questions
