From code to screenshot

How HCTI examples work

HTML/CSS to Image renders HTML and CSS in hosted Chrome, then captures the result as an image or PDF. Each example combines real source code with the API options used for the render, so it is both a working demo and a starting point for your own request.

Edit the source and options above to test changes in the browser, then render through the API to see the production result.

Common questions

Can I use the HTML and CSS from these examples?

Yes. Open an example to inspect and edit its complete HTML, CSS, and render options. Use it as a starting point, then send the resulting request from your application.

What is the difference between an example and a template?

Examples are complete API requests built from HTML and CSS. Templates are saved, reusable designs created in the visual editor and rendered repeatedly with different variable values.

Does HCTI create screenshots and PDFs?

Yes. HCTI can render HTML and CSS or capture a public webpage as an image, and it can generate PDFs when you need document output instead of a screenshot.
