SnapHTML Images

HTML to Image API

Convert HTML strings or live URLs into PNG and JPG assets for previews, reports, and screenshot-driven workflows.

Render HTML directly to PNG or JPG

Capture URLs for thumbnails and visual archives

Works alongside the PDF API in one stack

curl -X POST "https://snaphtml.one/api/image" \
  -H "content-type: application/json" \
  -d '{"url":"https://example.com","type":"png"}' \
  --output out.png

Common image rendering use cases

The API is useful when you need visual output but not a printable document, especially for preview cards, reporting snapshots, and content pipelines.

Preview Assets

Generate social cards, thumbnails, and internal previews from the same HTML you already control.

Operational Snapshots

Capture dashboards or webpages into JPG or PNG when downstream tools do not need full PDFs.

Shared Rendering Logic

Reuse the same markup and styling decisions across document and image output modes.

SnapHTML Workflow

Use HTML As The Source, Pick The Output Later

If your team already builds the view in HTML, image rendering should be a format choice, not a second implementation.
