What does the HTML Encoder/Decoder tool do?

The HTML Encoder/Decoder tool from PowerSEOTools.online converts special characters into HTML entities for safe display in web pages, and decodes HTML entities back into readable text. It supports common entities like <, >, &, ", ' plus numeric entities.

When should I encode HTML?

You should encode HTML when you want to display code snippets, user-generated content, or any text that contains tags in a way that the browser does not interpret as real HTML. Encoding protects layouts, prevents broken pages, and helps avoid XSS vulnerabilities when used correctly with server-side validation.

Is this HTML encoder/decoder free to use?

Yes. The HTML Encoder/Decoder is 100 percent free to use with no registration, login or usage limits. You can encode or decode as much content as you like.

Does this tool upload my text to your server?

No. All encoding and decoding happens directly in your browser using JavaScript. Your text is never uploaded, stored or logged on our servers, making it safe for code samples, templates, and client content.

Which characters are encoded by default?

By default, the tool encodes the most important HTML special characters: &, <, >, " and '. You can also enable an option to encode forward slashes, which is sometimes used for additional hardening.

Free Online HTML Encoder/Decoder

The HTML Encoder/Decoder from PowerSEOTools.online helps you safely display HTML snippets, code examples and user-generated content inside web pages and CMS fields. Instead of writing entities by hand, you can convert any text in seconds and avoid broken layouts or unintended HTML rendering.

Why Encode HTML?

Browsers treat characters like <, > and & as part of HTML markup. If you paste code directly into a page without encoding, the browser may interpret it as real tags instead of showing it as text. This can:

Break your layout or hide parts of your content.
Accidentally inject elements like images or links.
Make code examples unreadable in technical articles.

Encoding converts those characters into HTML entities, such as < and >, so the browser shows them literally instead of executing them.

Common Use Cases

Blog posts & documentation: Display HTML, CSS, JavaScript and template code in tutorials.
CMS & WYSIWYG editors: Prevent editors from stripping tags or altering your HTML snippets.
Comments & user content: Prepare text for safe rendering after server-side validation.
Email templates: Encode dynamic content before injecting into HTML email bodies.
SEO checks: Inspect how meta tags or snippets will look when properly escaped.

How the HTML Encoder Works

In Encode mode, the tool converts special characters to HTML entities:

& → &
< → <
> → >
" → "
' → '
Optionally / → / for extra hardening

In Decode mode, it reverses the process and turns entities like &, <, and numeric codes like < or < back into their original characters.

How to Use the HTML Encoder/Decoder

Choose Encode HTML if your input is raw HTML and you want entities.
Choose Decode HTML if your input already contains HTML entities.
Paste or type your content into the Input area.
Adjust options for which characters you want to encode.
Click Convert (or enable Live Update for automatic conversion).
Copy or download the output and use it in your editor, template, or CMS.

Privacy-Friendly and Browser-Based

All conversions are performed locally in your browser using JavaScript. No text is sent to any server, logged, or stored. This makes the HTML Encoder/Decoder safe for client code, internal snippets, and private documentation.
