HTMLCSS to Image API logo HTMLCSS to Image API

propzapi renders images from your own HTML and CSS templates. Send a template id and your data; it fills the placeholders, rasterises the page with headless Chromium, and returns a URL to the finished image — a social card, a quote, a certificate, or a chart drawn from your numbers.

Thirteen templates ship in the box, including bar, line and donut charts. Templates are real Jinja (if/for/filters), so a template plus your data becomes a table, list or chart — not just fill-in-the-blank text. Bring your own HTML whenever the built-ins aren't enough; there's no design tool to log into.

It also screenshots any public URL to an image, exports any template to a one-page PDF, and signs a GET URL you drop into a meta og:image tag so every page renders its own share image. Built for agents: a hosted MCP server lets a Claude or Cursor agent generate an image in one tool call and get the picture back inline.

One credit is one image, charged only when a render succeeds. 50-image free trial, no card.

HTMLCSS to Image API features and specs

  • Ease of Use
    The API allows users to convert HTML/CSS content to images with minimal code, making it accessible for developers.
  • Customization
    Users can have full control over the appearance of the generated images through HTML and CSS, enabling highly customizable output.
  • Efficiency
    The service automates the image generation process, allowing for quick and efficient conversion that saves development time.
  • Scalability
    The API can handle a large number of requests, making it suitable for applications that need to generate many images dynamically.

Possible disadvantages of HTMLCSS to Image API

  • Dependence on External Service
    Relying on an external API means there is potential for downtime or changes in service terms that could impact your application.
  • Cost
    Using the API might involve subscription or per-request fees, which could be a limitation for cost-sensitive projects.
  • Privacy Concerns
    Sending data to an external service for processing might raise privacy and security concerns, especially if sensitive information is involved.
  • Limited Control
    Users might have limited control over the underlying image generation process compared to setting up an in-house solution.

propzapi features and specs

  • Render-and-verify
    Pass the exact strings you expect and the response confirms each one rendered as visible text, not dropped or clipped. Proof the output is correct, which no other render API offers.
  • HTML and CSS templates to image or PDF
    Send a template with placeholders and your data; get back a finished PNG, JPEG, WebP or one-page PDF, rendered in real headless Chromium.
  • Screenshot any URL
    Capture any public web page to an image or a paginated PDF, with backgrounds preserved and lazy content scrolled in first.
  • Pay-as-you-go pricing
    A $5 pack covers 150 renders and never expires, and 50 are free to start with no card. A failed render is billed nothing.
  • Built for AI agents (MCP)
    A hosted MCP server exposes generate_image, screenshot_url and list_templates, so an agent renders and gets the image back inline.

Analysis of propzapi

Overall verdict

  • PropzAPI appears to be a real estate data API service, but there is limited independent, verifiable information available to fully confirm its reliability, data accuracy, and long-term support.
