HTMLCSS to Image API
Placid
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.
