HTML Decode String

HTML Decode String reverses HTML entity encoding, URL encoding, and mixed encodings so that you can recover human-readable content. Whether you are cleaning up CMS output, inspecting encoded query parameters, or converting stored HTML back into copy, the tool reveals the original characters instantly.

Features at a glance

• Entity decoder: Supports standard entities (<, &, quotes) as well as numeric and hexadecimal entities.
• URL decoding option: Toggle URL decoding to automatically convert percent-encoded text and “+” characters.
• Live preview: Enable auto-decode to see the plain-text result while you type or paste.
• File uploads: Load entire HTML snippets or encoded logs straight from disk.
• Sample generator: Quickly load a sample encoded URL to understand how the tool behaves.

Workflow

1. Paste encoded HTML, XML, or URLs into the left panel, or click “Load Sample Encoded URL”.
2. Keep “Treat input as URL-encoded” checked when working with query strings or form submissions.
3. Use the output panel to copy or download the decoded result. The output is plain text so it can be pasted directly into editors.
4. Disable auto-decode when working with large blocks of HTML and trigger decoding manually with the button.

When to use this tool

• Debugging API callbacks that double-encode JSON inside HTML entities.
• Reviewing RSS feed content that encodes markup for safety.
