Open .TSX files online
A .tsx file is TypeScript with JSX — the XML-like syntax for writing UI components popularized by React. The .tsx extension tells the compiler to parse JSX alongside TypeScript types, which is how virtually all React code written in TypeScript is organized.
JSX looks like HTML inside JavaScript (<Button onClick={…}>Save</Button>), but it compiles to function calls that create UI elements. Reading a .tsx is how you understand a component's structure and props without running it.
What is a `.tsx` file?
JSX is a syntax extension that lets you write element trees inline in JavaScript. Combined with TypeScript (.tsx), each component's props get static types. Compilers like tsc, Babel, or SWC transform JSX into React.createElement or the newer JSX-runtime calls, producing JavaScript.
A .tsx file is plain text (UTF-8). Like .ts, it must be compiled before a browser can run it; the viewer shows the source.
- React and React Native components
- Next.js and Remix pages and layouts
- Typed component libraries
- Any TypeScript UI codebase using JSX
How to open a `.tsx` online
Open the zip viewer in a new tab, then drop your .tsx onto the page — or click to browse for it, or paste a URL. The file opens in the Monaco code editor, with syntax highlighting, code folding, and find, read entirely on your device.
- Drag your
.tsxonto the page — or click to browse, or paste a URL. - It opens immediately in the Monaco code editor, with syntax highlighting, code folding, and find. No install, no sign-up.
- Read, search, or copy it. Your file never leaves your browser.
Open `.tsx` without uploading
Most "open tsx online" sites work by uploading your file to a server and processing it there. ZipTool does the opposite: it loads its parser once, then reads your .tsx locally in the browser tab. The contents stay on your device.
You can prove that in seconds. Open the page, press F12 for DevTools, switch to the Network tab, and open your file — no request carrying the file's contents is sent. You can also turn off Wi-Fi after the page loads and the file still opens. See security and privacy for the full picture.
Frequently asked questions
How do I open a .tsx file online?
Drag the .tsx onto the page (or click to browse, or paste a URL). It opens in the code editor so you can read the component markup and types, search, and copy — it is not compiled or executed. The file is parsed entirely in your browser and never uploaded.
Can I view a .tsx without uploading it?
Yes. ZipTool reads the file locally in your browser tab — no upload, no server-side copy. Confirm it with DevTools (F12, Network tab) while opening the file, or by turning off Wi-Fi after the page loads and verifying the file still opens.
What is the difference between .ts and .tsx?
Both are TypeScript. .tsx enables JSX parsing so you can write <Component /> syntax (used by React and similar libraries). .ts is plain TypeScript without JSX. Use .tsx for files containing JSX markup and .ts for everything else.
Is .tsx only for React?
JSX is most associated with React, but other frameworks (Preact, Solid, Qwik, Vue with JSX, Astro components) also use it. The .tsx extension just means "TypeScript with JSX"; which framework the JSX targets depends on the project's compiler configuration.
