Everything to Know About Our Free HTML Viewer
Quick answers about viewing, previewing and testing HTML code online.
Paste your HTML code into the editor and the output appears right beside it. There is nothing to install, no account to create and no file to save first. It works in any modern browser.
Yes. The preview updates as you type, so you can see the effect of every change straight away instead of saving the file and refreshing the page again and again.
All you need is a browser. Open the HTML viewer, paste or type your code and check the result on the same page. It is a quick way to test a snippet without setting up a code editor or a local server.
Yes. You can upload an .html file and see how it renders, which is handy when a page is saved on your computer and you want a quick look at it. If the file depends on separate CSS, JavaScript or image files, link them with full URLs so they load in the preview.
Yes, it is completely free. There is no signup, no trial period and no limit on how often you can use it.
Yes. Change your markup in the editor and the preview refreshes with it. That makes it easy to fix a broken tag, adjust a layout or try a small idea before you copy the code into your project.
Yes. You can add CSS inside style tags or inline, and JavaScript inside script tags, and both run in the preview. Files that live elsewhere need a full URL in your code to load.
Yes. The layout adjusts to phones and tablets, so you can paste code and check the result on a small screen too. For long files a desktop screen is more comfortable, but the tool works on both.
The best one is the one that fits your work. Look for a viewer that is free, needs no signup, shows a live preview and handles CSS and JavaScript. Our HTML viewer covers all of these and runs in the browser, so it opens in seconds.
Paste the page code into the viewer and look at the result first. Check that the layout, links, images and text appear as you expect, then test it on a phone-sized screen as well. Fixing mistakes here is much easier than after the page goes live.
