How to Convert TSX to HTML - Step by Step Guide

Step 1

Input Your TSX Code

Let's convert your React TypeScript TSX to standard HTML! Whether you're extracting markup from type-safe components, creating static pages, or working with non-React environments, you have several convenient options:

•
Paste directly: Bare markup, a return block or a whole component file all work, imports and interfaces included
•
Upload a file: Click "Upload" to pick a .tsx, .jsx, .ts, .js or .txt file (up to 5 MB)
•
Try the sample: Click "Sample" to load example TSX and see how the converter works

Example: TSX Input

Here's what React TypeScript TSX looks like:

interface Props {
  title: string;
}

<div className="container">
  <h1 className="title">Welcome</h1>
  <button onClick={handleClick}>
    Click Me
  </button>
</div>
Step 2

Automatic Conversion & Transformation

A moment after you stop typing, the converter renders your code the way React would:

•
Removes TypeScript types: Interfaces, annotations, generics, enums and as casts are ignored
•
Converts attributes: className to class, htmlFor to for, strokeWidth to stroke-width, style objects to CSS text
•
Removes event handlers: onClick, onChange, key and ref have no meaning in plain HTML, so they go

Example: Clean HTML Output

The same markup, now as standard HTML:

<div class="container">
  <h1 class="title">Welcome</h1>
  <button>Click Me</button>
</div>
Step 3

Review the HTML Output

Read the HTML together with the notes above it. The notes tell you what couldn't be worked out from the code alone:

•
Careful formatting: Block elements get their own indented lines; text and inline tags stay on one line, so no spaces appear that React wouldn't render
•
Placeholders: Props nobody passed or data from an API show up as {user.name}-style placeholders, or can be hidden
•
Marked sections: Conditions and loops that depend on runtime data sit between <!-- if … --> and <!-- for each … --> comments
Step 4

Export Your HTML

When it looks right, take the HTML with you:

•
Copy to clipboard: One-click copying for quick pasting into your HTML file
•
Download as file: Saves output.html, encoded as UTF-8 so accents and emoji survive
•
Live updates: Edit the TSX and the HTML follows; your last input is kept in this browser after a refresh

Frequently Asked Questions

What is TSX to HTML conversion?

It takes React markup written in TypeScript (TSX) and turns it into the plain HTML React would put on the page. That helps when you need static markup from a component: an email template, a quick prototype, a CMS block, or a page that doesn't run React at all.

Can I paste a whole component, or only the JSX?

Either works. You can paste bare markup, a return (...) block, or a full file with imports, interfaces and several components. The converter renders the default export (or the component nobody else uses), fills in props from their default values, runs .map() over arrays defined in the code, takes initial values from useState, and expands components defined in the same file.

What happens to props, state and data that only exist at runtime?

Anything the code alone can't tell, like a prop nobody passed or data from an API, is written as a {placeholder} showing the original expression, and listed in a note above the output. A condition it can't decide keeps both branches between <!-- if … --> comments, and a .map() over unknown data shows one example item. Choose "Hide unknowns" if you'd rather leave those values out.

Which TSX attributes are converted?

Everything React renames: className becomes class, htmlFor becomes for, tabIndex, readOnly, maxLength and friends are lowercased, SVG props like strokeWidth become stroke-width, and style={{ marginTop: 10 }} becomes style="margin-top: 10px". Event handlers such as onClick, plus key and ref, are removed because plain HTML has nothing to call them.

How are TypeScript types handled?

Interfaces, type aliases, enums, type annotations, generics, as casts, satisfies and the ! operator are all read and then ignored, so none of them reach the HTML.

Is the HTML output safe and ready to use?

Text and attribute values are escaped, so a < or a quote in your data can never turn into a tag. Content you put in dangerouslySetInnerHTML, a <script> element or a javascript: link is kept exactly as written, with a note, because that is what your component asks for. Review those before you publish. Nothing you paste is run on this page; the output is shown as text only.

Is the tool free, and where does my code go?

It's free and needs no sign-up. The conversion happens in your browser, and your code is not uploaded anywhere. The last thing you typed is kept in this browser's local storage so a refresh doesn't lose it. Uploads can be up to 5 MB.
