Use Cases

Visual content that creates itself

Real scenarios where businesses use AI agents to produce images from HTML templates during customer interactions, eliminating manual design work for repetitive visual assets.

Personalized Certificates Generated on Completion

A student finishes an online course and messages the chatbot for their certificate. Your AI Agent populates an HTML certificate template with the student's name, course title, and completion date, sends it to the HTML to Image API, and delivers a polished PNG certificate in the conversation. The student gets their credential instantly. No designer or manual process involved.

Dynamic Social Media Cards for Content Marketers

A content team publishes a new blog post and needs an Open Graph image. They tell the agent the title and author. Your AI Agent renders the branded HTML template with the post details at 1200x630 pixels using the HTML to Image API and returns the image URL. The team pastes it into their CMS. Consistent, branded social cards produced in seconds instead of opening a design tool.

Real-Time Receipt Images for E-Commerce Orders

A customer asks for a visual receipt of their order. Your AI Agent pulls the order details, populates an HTML receipt template with line items, totals, and branding, and converts it to a downloadable image through the API. The customer receives a clean, branded receipt image in the chat. Your support team never touches a design tool for transactional documents.

FAQs

Frequently Asked Questions

How does the AI agent convert HTML into an image?

The agent sends your HTML content (including inline CSS and JavaScript) to the HTML to Image API's conversion endpoint. You can specify width and height in pixels. The API renders the page and returns either a downloadable image file or a JSON response with the image ID and hosted URL.

What image formats does the API support?

The API generates PNG images by default. When retrieving a generated image by ID, you can append .png, .jpg, or .webp to select the format. This lets your agent deliver the same design in multiple formats without re-rendering the HTML, which is useful for print versus web use cases.

What authentication does Tars need for HTML to Image?

Tars uses your HTML to Image API key, which you obtain from your account dashboard at html2img.com. This key authenticates all requests including image conversion, retrieval, and usage checks. You can regenerate the key anytime from your account settings.

Does Tars store the generated images?

No. Tars passes the HTML to the API and forwards the resulting image URL or file to the customer. The generated images are stored by the HTML to Image service. Tars does not cache or retain any image files.

Can the agent generate images with custom dimensions?

Yes. The agent specifies width and height parameters in the API call, controlling the exact pixel dimensions of the output image. The API supports dimensions up to 5000x5000 pixels. For retrieval, you can also resize images by passing different width and height values.

How is this different from using a screenshot tool?

Screenshot tools capture existing web pages. The HTML to Image API renders arbitrary HTML and CSS you provide, including dynamic data like customer names, order details, or generated content. Your agent produces fully customized images from templates, not just snapshots of existing pages.

Does the API support JavaScript in the HTML content?

Yes. The HTML to Image API executes JavaScript in your HTML content before capturing the image. Scripts have a maximum execution time of 30 seconds. This enables dynamic content like charts, animations frozen at a specific frame, or conditionally rendered elements.

Can the agent track how many images have been generated?

Yes. The agent calls the usage endpoint to retrieve hourly, daily, and monthly image creation counts. This helps your team monitor consumption against plan limits and track usage trends over time. If the endpoint is unavailable, the agent returns safe defaults.

“Powerful tool - and there's so much more still to explore!”
I love the flexibility of the TARS chatbot design tool. The ability to drop in a new gambit and easily de-link and re-link gambits before and after it saves HOURS of time lost if I had to regenerate from scratch. TARS stands out for its flexibility, consistent performance, and outstanding support.

TARS is an essential tool within our lead gen strategy. I started to use it a couple years ago, and the platform evolved to focus on results. You can integrate your Google Analytics, Facebook Pixel, and AdWords conversion tag to track results and measure your campaign. You can also integrate with Zapier, which opens a lot of possibilities.
