      Overview

      What an HTML viewer does

      View the code behind any web page - fetched, formatted, and syntax-highlighted - without installing a thing.

      An HTML viewer takes a web page's underlying source code and shows it to you in a clean, readable form. Instead of the rendered page - the headings, images, and buttons you normally see - you get the HTML markup underneath: the tags, attributes, and text a browser uses to build the page.

      Paste any public URL and this viewer fetches the page's HTML directly from the server, pretty-prints it with proper indentation, and colour-codes the syntax so tags, attributes, and values are easy to tell apart. Minified pages that ship as one giant line become neatly structured and browsable.

      Because the HTML is fetched server-side, you see the same markup a search engine receives on its first visit - before any client-side JavaScript runs. And because it all happens in the browser, you can read a page's source on a phone or tablet, where there is no built-in "view source" option at all.

      Use Cases

      What people use an HTML viewer for

      From learning to debugging to on-the-go inspection - here is where a formatted HTML view helps.

      🔍

      Read Minified HTML

      Turn a page that ships as one unreadable line into cleanly indented, syntax-highlighted markup you can actually follow.

      🎓

      Learn From Real Pages

      See how professional sites structure their markup, meta tags, and semantic elements - one of the best ways to learn HTML.

      🔧

      Debug & Inspect Markup

      Check how a page is built, find where a tag or attribute lives, and verify content is present in the server-rendered HTML.

      📱

      View Source on Mobile

      Phones and tablets have no native "view source". Paste a URL here to read any page's HTML on the device you already have.

      🌐

      Check SEO & Meta Tags

      Confirm where the title, meta description, Open Graph, and structured data sit in the raw HTML a crawler first sees.

      • Works on any device, including phones and tablets
      • Includes basic page & server info below the code
      • No install, no sign-up, completely free

      Prefer the exact bytes the server sent? Turn off formatting and the viewer shows the unmodified HTML response, character for character.

      How it works

      From URL to readable HTML in three steps

      What happens between pasting a link and reading the formatted source.

      1. Paste a URLEnter the full address of the page whose HTML you want to view and press View HTML.
      2. We fetch it server-sideOur server requests the page directly and receives the raw HTML - no JavaScript is executed, so you get the original markup.
      3. Read, copy, or downloadThe HTML is formatted and syntax-highlighted for you. Scroll it, copy it to your clipboard, or download it as an .html file.

      FAQ

      Frequently asked questions

      Common questions about viewing and formatting HTML.

      What does an HTML viewer do?

      An HTML viewer fetches a web page and shows you its underlying HTML source code in a clean, readable form. Instead of the rendered page, you see the markup - the tags, attributes, and text a browser uses to build the page - formatted and syntax-highlighted so it is easy to read.

      How is this different from my browser's 'view source'?

      Browser view-source shows the raw HTML exactly as the server sent it, often minified onto a few very long lines. This viewer formats and indents that markup, adds colour-coded syntax highlighting, and works on mobile browsers that have no built-in view-source option at all.

      Does it format and beautify the HTML?

      Yes. With formatting on (the default), the viewer pretty-prints the HTML - indenting nested elements and putting tags on their own lines - so even heavily minified pages become readable. Turn formatting off to see the exact bytes the server returned.

      Can I view the HTML of any website?

      You can view the HTML of any publicly accessible page. Enter its URL and the viewer fetches the server's HTML response. Pages behind logins or paywalls, or that block automated requests, may not be viewable.

      Does it show HTML added by JavaScript?

      No. The viewer shows the raw HTML returned by the server, before client-side JavaScript runs - the same starting point a search engine sees. Content injected later by frameworks such as React or Vue will not appear.

      Can I view HTML source on my phone?

      Yes. Mobile browsers do not offer a native view-source option, so this viewer is one of the easiest ways to read a page's HTML on a phone or tablet. It works on any device with a browser.

      Can I copy or download the HTML?

      Yes. Use the Copy button to put the formatted HTML on your clipboard, or Download to save it as an .html file.

      Is it free and private?

      The HTML viewer is completely free with no sign-up. We do not store your queries or tie them to your identity, and responses are cached only briefly for speed. See our privacy policy for full details.
