HTML/CSS to Image for agents
Ask your assistant to capture a webpage, check a mobile layout, or turn a design into an image. HTML/CSS to Image handles the browser and returns a file you can use.
Start with 50 free images each month. See plans.
Use HTML/CSS to Image to screenshot [your public URL] at desktop and mobile sizes. Return both image URLs so I can review the layouts.
Both captures are ready. On mobile the headline wraps to three lines and pushes the button down. Want me to try a shorter version?
Daily visual checks
Ask your agent to check your site on phones, tablets, and desktops. Have it look for cut-off text, overlapping sections, or a signup button that has disappeared.
Your agent handles the daily check and reviews the screenshots from HTML/CSS to Image. You get the images and a clear explanation of anything that needs attention.
Put screenshots to work
Use screenshots as visual context, research evidence, or a finished deliverable. Try these prompts with your own URLs and content.
Give a vision-capable coding agent a fresh view of your deployed preview. Check spacing, clipped text, and missing content against the design you intended.
Try asking
Use HCTI to screenshot [public preview URL] at 1440 × 900 and 390 × 844. Open both images and flag any clipped text or overlapping elements.
Capture the same page with consistent browser settings. Compare desktop and mobile layouts, or check how a site responds to a dark color-scheme preference.
Try asking
Capture [your public URL] at a 390 × 844 mobile viewport in light and dark mode. Use HTML/CSS to Image and return a labeled image URL for each.
Collect current screenshots of product pages, pricing pages, or campaign landing pages. Keep the source URLs beside the images so your team can follow the research.
Try asking
Use HCTI to take a full-page screenshot of each URL in this list. Return the source page and screenshot URL together for my research brief: [public URLs].
Turn a live product page or a single component into an image for a guide, launch note, or support reply. A CSS selector keeps the capture focused on the relevant section.
Try asking
Screenshot [your public URL] with HCTI. Capture only the element matching [CSS selector from the page], and return a PNG image URL for our guide.
Ask your agent to design with HTML and CSS, render the result, and refine it. Create social cards, product announcements, or a set of variations from a saved template.
Try asking
Create a 1200 × 630 launch card for [product name] using [brand colors] and this headline: [headline]. Render the HTML/CSS with HCTI and return the image URL.
Give your assistant the content, then ask it to lay out a readable document. Export research summaries, proposals, and reports as PDFs you can download and share.
Try asking
Format this report as HTML/CSS with clear headings and a readable table. Render it as a PDF with HTML/CSS to Image and return the PDF URL: [report content].
Replace bracketed URLs, selectors, and content with your own. Use URLs reachable from HCTI’s hosted browser; a server running only on your computer needs a public preview URL.
Connect your HCTI account once, then ask for screenshots in your conversation or coding task. Sign in through your browser; there is no API key to paste into a prompt.
Capture a page in a conversation or bring screenshots and rendered assets into a coding task.
Use the Claude connector for conversations, or connect Claude Code for rendering alongside your project.
Ask your coding agent to capture a deployed preview or render HTML/CSS from the project you are editing.
Add screenshots, image generation, and reusable template workflows to your terminal tasks.
Capture public pages and generate visual assets while working through a coding task with Copilot.
Connect HCTI's rendering tools to your OpenCode agent and return screenshots or PDFs from a prompt.
Install the official HTML/CSS to Image plugin from Grok Build's marketplace. Capture webpages, render images and PDFs, and work with saved templates.
Use VS Code, Cline, Windsurf, or another compatible assistant. Find your client in the connection guides.
The integrations connect through HCTI’s hosted MCP service. Follow your client’s guide for installation and permissions. If you are building your own agent, you can also call the REST API directly.
I use HCTI with my Claude Code and NetClaw agents over MCP to generate social media, web, and YouTube content every month. Tremendously valuable.

Hosted or self-hosted
You can take screenshots with Puppeteer. The choice is whether your agent needs to operate a browser or needs a rendered file. HCTI handles the browser infrastructure and makes the capture a request with explicit inputs and a hosted result.
| Your task | Hosted rendering with HCTI | A browser you operate |
|---|---|---|
| Capture a public page or supplied HTML/CSS | Send the input and capture options; receive a hosted image or PDF URL. | Write or run browser automation and decide where to save or upload the result. |
| Repeat a capture across agents or teammates | Use the same capture settings, HCTI organization, and saved templates. | Keep browser dependencies, runtime settings, and output handling aligned yourself. |
| Navigate, click, or inspect a local application | Use a separate browser tool for interaction; HCTI can capture a publicly reachable preview. | Use the browser's interactive controls and access to your local environment. |
HCTI captures the URL or markup you provide in its own hosted browser. Your agent never touches your everyday browser profile or its signed-in sessions.
Viewport, device scale, color scheme, timezone, and timing travel with the request, so a mobile screenshot means the same thing from Claude, a coding agent, or a teammate.
The agent picks a URL, size, crop, and format, then gets an image URL back. There are no debugging ports, local Chrome processes, or upload steps to manage.
