The Chrome extension gives me really high-fidelity screens - I never get that level of fidelity in other platforms. I hand them straight to engineers.

The screen capture copies the exact layout and UI of our system. And the select button is a lifesaver.

Alloy captures web screens in seconds - even pages behind a login. Most other tools can't do this.
Caroline Gao
Director of Product, Pragma
Other tools rebuild your product from scratch and often get it wrong. With Alloy you capture the page and go. I use it almost every day.

Alloy gives me fast prototypes that look exactly like my product - that's the big differentiator. My team instantly gets what I mean.

With other tools, users would get lost. Alloy lets me prototype inside an interface that already feels familiar to them.
Snapshots beat screenshots
Screenshot-to-code tools look at a flat image and generate their best approximation. Alloy snapshots the rendered page, so the HTML is the page.
| Capability | Screenshot-to-code AI | Alloy |
|---|---|---|
| Source material | A flattened PNG or JPG the model must reinterpret | The rendered page itself — markup, styles, fonts, and assets |
| Accuracy | A close guess — spacing, colors, and type tend to drift | Pixel-perfect, because nothing gets redrawn |
| Hidden UI states | Dropdowns, modals, and hovers are lost in the flat image | Interactive states come through as editable HTML |
| Price | Credits per generation, with quality varying run to run | Converting a page to HTML is free |
Working at the level of whole sites rather than single screens? The Alloy website cloner uses the same capture engine.
Frequently asked questions
An image to HTML converter turns a picture of an interface — a web page, an app screen, a mockup — into working HTML and CSS. Most converters run AI over a screenshot and generate an approximation of what they see. Alloy works one level deeper: it snapshots the rendered page itself, so the "image" you point at comes back as the exact markup behind it.
When you paste a URL or capture a screen with the Chrome extension, Alloy takes a snapshot of the page exactly as it is displayed — every pixel you see — and returns it as real HTML, CSS, fonts, and assets. There is no reconstruction step, which is why the result matches the original down to the pixel instead of being a best-effort redraw.
Yes. If all you have is a static image file — a screenshot from a teammate, a mockup export — attach it in Alloy chat and ask for HTML, and the AI will build the page from the picture. If the interface is live anywhere in a browser, capture it instead: a capture skips the guesswork entirely and gives you the exact markup.
Yes. The Chrome extension snapshots whatever your browser is currently displaying, so dashboards, admin panels, checkout flows, and internal tools convert to HTML just as easily as public pages. URL-only converters never see those screens.
A flat screenshot destroys them — a dropdown becomes a rectangle. Because Alloy snapshots the live page, open menus, modals, and other UI states are preserved as real HTML you can open, close, and edit afterwards.
Yes. You get the page’s actual structure and stylesheets rather than machine-generated markup soup. Edit it by hand, select elements visually, or describe the change you want in AI chat — swap copy, colors, components, or whole layouts.
Yes. The converted page is backed by real HTML and CSS, and you can export that code into your own project. You can also skip the export and share the result as a live, clickable prototype link instead.
No. The conversion is one click, and every edit after that can be made in plain language through AI chat. Developers can still open and refine the underlying code whenever they want more control.
Anything you would build with a hand-coded page: redesigns, A/B test variants, pitch mockups, or full prototypes. Alloy's website cloner uses the same capture engine when you want to work at the level of whole sites, and our guide to the best AI prototyping tools compares what to do next.
Yes. Converting pages to HTML, editing them, and sharing prototypes is free, with no credit card required. Paid plans add higher limits and team features.
You may only convert pages you own or have the necessary rights and permissions to capture and use. Alloy's Terms of Use require lawful use of the Services, so confirm you are authorised before converting someone else's interface, content, or assets.
