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.

Possible disadvantages of HTML PDF API

  • Cost
    Depending on your usage, HTML PDF API can become expensive, particularly for large-scale operations requiring high volume or premium features.
  • Dependency on Internet Connectivity
    Being a cloud-based service, it requires a stable internet connection, which can be a limitation in environments with poor connectivity.
  • Latency
    Network latency can affect the speed of PDF generation, which may impact time-sensitive applications.
  • Rate Limiting
    Usage may be subject to rate limiting, potentially hindering the performance of high-demand applications or requiring additional cost to increase limits.
  • Privacy Concerns
    Sensitive data needs to be transmitted to a third-party server for processing, which could raise privacy and compliance concerns depending on jurisdiction and data sensitivity.
  • Potential Downtime
    As with any cloud-based service, there is a risk of downtime or service disruptions due to server issues or maintenance.

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.
