Have you ever pasted web copy and seen < or & sitting in the middle of a sentence? Those are HTML entities, and the HTML Decoder turns them back into the real characters they stand for.
This tool is for developers, writers, and support staff who deal with encoded markup. You paste entity text, and the plain character result shows up as you type.

What the Tool Does
The HTML Decoder reads one text box and writes one result box. It converts HTML entities into the characters they represent.
- Named entities: codes like <, >, &, and " become the symbols <, >, &, and ".
- Numeric entities: decimal codes like € and hex codes like ❤ become their Unicode characters.
- Live output: the result updates on every keystroke, and a Decode button repeats the action.
- Copy button: one click copies the result to your clipboard and shows a short status.
The three cards at the top are fixed labels. They read Mode Decoder, Input Format HTML Entities, and Output Decoded Text. They do not change with your input.
How to Use It, Step by Step
- Paste your encoded text into the HTML Entity Input box. A sample loads when the page opens.
- Watch the Decoded Text Result box fill in as you type.
- Press Decode HTML Entities if you want to run it again by hand.
- Click Copy to put the decoded text on your clipboard.
- Clear the input box to clear the result. An empty box shows a short prompt to paste codes.
How the Decoding Works
The tool loads your text into a hidden text area, which the browser treats as plain text. Each entity is decoded against the standard table, while everything else stays as typed.
< > &→Entity Decoder→< > &
There is no custom math here, just a lookup against the standard entity table. Any real tags you paste are kept exactly as they are, so no content is lost.
Worked Example
Priya copies three snippets from a database export. She pastes each one and reads the decoded result. The table shows what the tool returns.
| Encoded Input | Decoded Result |
|---|
| <a href="/x">Link</a> | <a href="/x">Link</a> |
| Café © 2026 €50 | Café © 2026 €50 |
| <p>Price 5 &gt; 3 &amp; true</p> | <p>Price 5 > 3 & true</p> |
The first row rebuilds a full tag from its encoded form. The second row mixes a named, a decimal, and a currency code. The third row shows that double encoded codes only step back once.
How to Read the Result
The result box holds plain text, not rendered HTML. If the decoded text is a tag like <a>, you see the tag as characters, not a working link.
That is the point of a decoder. You get the raw source back as text. Then you can read it, edit it, or paste it elsewhere.
The output box is read only. Use the Copy button rather than editing the result in place.
One Level of Decoding and Real Tags
The tool decodes one layer only. The input &gt; turns into >, not into >, because the first & becomes a single ampersand.
When a layer of codes is left over, a short note appears under the result. It reminds you that text encoded twice needs a second pass through the decoder.
Real tags behave differently. If you paste text that already has real tags, those tags are kept just as you typed them. Only the encoded codes change. Pasting <b>Bold</b> as raw markup returns the same <b>Bold</b> text. To reformat decoded markup instead, try the HTML Beautifier.
For the reverse job, where you turn < and & into safe entity codes, use the HTML Encoder. For XML content, the XML entity decoder handles that markup. You can find both jobs across the developer tools hub.
Limitations and Assumptions
- Output is plain text in a read only box. It is never shown as a live web page, so pasted scripts cannot run here.
- Real HTML tags in your input are kept as text, not turned into working elements.
- Decoding runs one level deep. Text encoded more than once needs more than one pass.
- There is no character limit, but very large pastes show a short wait notice while they decode.
- The Copy button tries the modern clipboard first and falls back when a page blocks it.
- This is not URL or Base64 work. For web address text use the URL Decoder, and for encoded binary use the Base64 Decoder.
FAQs About the HTML Decoder
What is an HTML entity?
An HTML entity is a code that stands for a character with a special meaning in markup. For example, < stands for the less than sign, and & stands for an ampersand.
Does the decoder change my text if there is nothing to decode?
Plain text with no entity codes comes back unchanged. The tool only replaces codes it recognizes and leaves the rest of your text alone.
What happens to real tags in my input?
They stay in place as plain text. The decoder keeps your tags exactly as typed and only swaps entity codes for their characters.
Can I decode many lines at once?
Yes. Paste as many lines as you need, and every code on every line is decoded in one pass.
Is my text sent to a server?
No. The decoding runs in your browser using its built in text handling. Your input is not uploaded by this tool.
Why does one ampersand code stay after decoding?
Codes like &gt; were encoded twice. One pass turns & into a single ampersand, leaving gt behind. Run the result through again to finish.
