About HTML Encoder & Decoder

An HTML decoder turns escaped markup such as <div> or numeric entities such as h back into the characters they stand for, and the same tool encodes in the other direction so text can be shown on a page without being parsed as markup. Paste a blob of entity-encoded HTML to deobfuscate it and read what it actually says, or encode a snippet before pasting it into a .com template.

Key Features

Decodes named entities, numeric entities and hex entities back to plain characters
Deobfuscates markup hidden behind long runs of numeric entities so you can read it
Encodes tags and special characters into safe entities for display inside a page
Preserves existing entities during encoding instead of double-escaping them
Accepts a pasted snippet or an uploaded file for larger batches
Validates as you type and copies or downloads the result in one click

Use Cases

Reading an entity-obfuscated script found in a phishing email or a defaced page
Showing raw HTML examples in documentation without the browser rendering them
Encoding user-submitted text before display to close off an XSS vector
Cleaning entity-encoded HTML pulled out of a database column or a CSV export
Decoding markup that arrived double-escaped from an email template or a CMS
Checking what an obfuscated ad tag actually injects before allowing it on a site

How do I deobfuscate HTML that is hidden in numeric entities?

Paste the whole blob and run decode. Obfuscated markup usually replaces every character with a numeric entity such as &#60;&#115;&#99;&#114;&#105;&#112;&#116;&#62; so that a scanner reading the raw source sees no tags, and decoding turns that straight back into readable HTML. If one pass still looks encoded, decode again: attackers often escape the ampersands as well, so the payload is entity-encoded twice. Read the result, do not paste it into a live page.
