HTML Encoder
Fixpio’s HTML encoder turns special characters in your code into HTML entities, right here in your browser. Paste a snippet, press Encode HTML, and copy a version that displays safely as text instead of running as markup — with nothing uploaded and nothing to install.
Encode HTML
Paste HTML or code, then encode it to entities.
Why developers keep an HTML encoder open
Three everyday jobs this page handles without a plug-in or an upload.
Publish code examples safely
When you write a tutorial or a help article, an encoded snippet displays exactly as you typed it, so readers can copy the code instead of seeing a half-rendered page.
Fix broken pages quickly
A stray tag in a post can swallow the text after it or change a layout. Encoding that tag stops the browser treating it as markup, and the rest of the page stays intact.
Keep entities correct
Encoding in a fixed order, ampersand first, means an existing entity stays intact and the output can be pasted into HTML and read back exactly as intended.
About this encoder
Most people reach for an HTML encoder when code needs to appear on a page without being treated as code. A tutorial showing a snippet, a help article explaining a tag, or a comment containing a less-than sign can break a layout or vanish entirely if the browser reads the text as markup. This page is built for that moment: open it, paste your HTML, press Encode HTML, and copy the result into your page or post. No account is needed, nothing is installed, and your text never leaves your device.
The conversion follows a fixed order that matters. The ampersand is encoded first, then the angle brackets and the two kinds of quotation mark, so a character already forming an entity is not encoded a second time. That consistency is the advantage over escaping by hand, where a missed quote or bracket in a long snippet is easy to overlook. Use the companion decoder when you need to reverse the process and turn entities back into readable characters.
Frequently asked questions
Straight answers about encoding, entities and privacy.
How do I encode HTML on this page?
Paste your HTML into the Input box and press Encode HTML. The encoded version appears in the Output box, ready to copy into your page, template or post.
What characters does the HTML encoder change?
It changes five characters: the ampersand, the less-than and greater-than signs, and double and single quotation marks. Each becomes the HTML entity for that character, so a browser shows it as text rather than reading it as markup.
Will encoding change text that is already an entity?
No, when the order is followed. The ampersand is encoded first, and the other replacements do not re-encode the characters that make up an existing entity, so a correctly written entity stays intact.
Is it safe to paste private code into this tool?
Yes. The conversion runs entirely in your own browser and your text is never sent to a server, stored by us or seen by anyone else. When you close the tab, nothing of it remains with us, because it never left your device.
Why does encoded HTML display as text instead of running?
A browser only treats text as markup when it sees the raw special characters. Once those characters are entities, the browser displays them literally, so a tag is shown as text and does not create an element, a link or a script.
What is the difference between encoding and decoding HTML?
Encoding turns special characters into entities so code can be displayed safely. Decoding does the reverse: it turns entities back into the original characters, so encoded text becomes readable, editable code again. Fixpio has a separate HTML Decoder for that job.
