Mobile browsers have never supported the view-source: shortcut, so reading a page’s HTML on a phone usually means giving up or finding a desktop. Paste a URL here instead: the page is fetched server-side and its full source renders in your mobile browser with syntax highlighting, search, copy, and download.
Read a page’s source on your phone
Paste any public URL into the analyzer to read its raw source, run the SEO audit, grade its security headers, and detect the technologies it uses — free, with no signup and nothing stored.
Typing view-source: before a URL is a browser scheme trick, not a web standard. iOS Safari has never implemented it, and Chrome on Android does not expose it in the address bar — so the one shortcut every desktop guide recommends simply does not exist on a phone.
There are no developer tools to fall back on
Chrome DevTools and the Safari Web Inspector are not available inside a mobile browser. Inspecting the DOM on a phone normally means tethering to a desktop and enabling remote debugging over USB — a reasonable workflow at a desk, and a useless one on a train.
Extensions and bookmarklets do not save you
Mobile browsers have a thin extension ecosystem at best, and the bookmarklets that paste a view-source: URL inherit exactly the same missing support. Saving one as a bookmark does not make the browser able to render it.
Long-press never offers it
Holding on a link gives you Copy link, Open in new tab, or Share — never “View page source”. The mobile UI has no entry point for raw markup, which is why the feature is so often assumed to be impossible.
The HTML was always there
The server delivers the same markup to a phone as it does to a desktop. The bytes are already on your device; only the browser interface hides them. Fetching the page server-side and rendering the source in the browser sidesteps the missing UI entirely.
How to read source on a phone or tablet
Open the analyzer on your phone
Navigate to viewsourceonline.com in any mobile browser — Safari, Chrome, Firefox, Samsung Internet, or an in-app browser. Nothing needs to be installed and no desktop is involved.
Paste the URL
Type or paste the address you want to inspect. A bare domain works; https:// is added for you, and the host is validated before anything is fetched.
Read the source in the viewer
The page is fetched once by our server and its complete HTML is rendered inline with syntax highlighting. The viewer has its own scroll context, so reading source never breaks the page layout around it.
Search, wrap, copy, or download
Jump straight to the tag you care about, wrap long lines so nothing runs off the screen, copy the document to the clipboard, or save it as a file you can open later on a desktop.
What is tuned for a small screen
Syntax highlighting that survives a narrow column
Tags, attributes, and values stay visually distinct even when the viewport is only a few hundred pixels wide, so you can still tell structure from content at a glance.
Search with matches highlighted
Type two or more characters and every match is highlighted inside the source. The first match is scrolled into view automatically, which beats pinch-zooming around a wall of markup.
A wrap toggle for long attribute lines
Inlined data URIs and long class lists are the usual reason source becomes unreadable on a phone. Wrapping keeps every line inside the viewport instead of forcing sideways scrolling.
No extension, no desktop, no tether
Everything runs in the browser you already have open. There is nothing to enable in settings and no USB debugging session to start.
The rest of the analysis travels too
Page speed timings, server and TLS details, page info, the SEO audit, security header grading, and technology detection are all in the same responsive result — so a phone is enough for a full review, not just a source peek.
Works the same on tablets
iPadOS and Android tablets get the identical viewer, usually with enough width that the source reads much like it does on a laptop.
FAQ
Mobile view source FAQs
The questions people ask most about this tool — and the limits worth knowing before you rely on it.
Can I view source on an iPhone or iPad?
Not with a browser shortcut. Safari on iOS and iPadOS has never implemented the view-source: scheme, and there is no equivalent menu item, so the desktop trick simply has no counterpart. This tool works in Safari on a phone because the fetching happens on our server and only the result is sent to your screen.
Does view-source: work in Chrome on Android?
Chrome on Android does not expose view-source: in the address bar, and behaviour has varied across versions, so it cannot be relied on. Even where a build accepted the prefix, it was an undocumented side effect rather than a supported feature.
Is there a view source extension for mobile browsers?
Not a practical one. Mobile browsers restrict extension installation heavily, and the few that allow it have no established view-source add-on. Bookmarklets that navigate to a view-source: URL fail for the same reason the prefix itself does.
Will it work inside an in-app browser?
Usually, yes — the analyzer runs in whatever browser engine the app provides. Some in-app browsers restrict navigation or scripting, so if a page will not load, choose Open in browser and retry in Safari, Chrome, or Firefox.
Does it use much mobile data?
Roughly the size of the page you inspect, because the fetched HTML is delivered to your device as part of the result so it can be highlighted, searched, and copied locally. There is a 5 MB ceiling on the source we hold, which bounds the cost of even a very heavy page.
