HTML to Image API

Render URLs, HTML, and templates as PNG, JPEG, WebP, or GIF from your backend.

From application content to image

Web pages, HTML and CSS, and data templates flow through the HTML to Image API and return an image.

Convert HTML or a URL to an image with one API call

Send an HTML file or a webpage URL and save the result as a PNG image.

# HTML file to image
curl --user "demo:demo" \
  --form "output_format=png" \
  --form "file=@document.html" \
  --output "from-file.png" \
  https://api.pdfcrowd.com/convert/24.04/

# URL screenshot
curl --user "demo:demo" \
  --form "output_format=png" \
  --form "url=https://example.com" \
  --output "from-url.png" \

Use a URL or send the HTML directly

Capture a webpage that already has a URL, including pages that use cookies or HTTP authentication. For images built from application data, send raw HTML and CSS, an HTML file or archive, or a data-driven template without publishing an intermediary page.

Running your own renderer for webpage screenshots and HTML-to-image conversion means installing and updating a browser, managing workers and memory, and diagnosing differences in fonts and dynamic content. PDFCrowd runs the renderer and returns the image. Your application decides what to render, then stores, serves, or publishes the result.

Control the capture

Capture area

  • Full-page captures
  • Fixed-height captures
  • Individual elements

Image output

  • Dimensions and scale
  • Output format
  • Background

Rendering controls

  • Custom CSS and JavaScript
  • Viewport behavior
  • Waits for dynamic content

Common uses

  • Webpage screenshots
  • Open Graph and social images built from HTML templates
  • Reports and dashboard snapshots
  • Tickets and certificates generated from application data

Other PDFCrowd products and tools

Use the HTML to Image API when your backend supplies a URL or HTML and decides when to create the image. For a different input, output, or trigger, use the matching product or tool.

HTML to PDF API

Render the same kinds of URL or HTML input as a PDF rather than a raster image.

WebSave as Image

Let a website visitor save the page they are viewing as an image.
