HTML/CSS to Image
Turn HTML, live URLs, or reusable templates into images and PDFs with one API without a to
HTML/CSS to Image (HCTI) is a browser rendering API operated by Code Happy, LLC that converts HTML and CSS, live public URLs, or saved templates into PNG, JPG, WebP, or PDF files. Rendering runs on managed headless Chrome, so users do not need to install, update, or scale browser infrastructure themselves.
Access is available through a REST API, official typed clients for TypeScript, C#, Python, Ruby, PHP, and Go, an MCP server for AI tools, and no-code automation platforms including Zapier, Make, and n8n. Features include a visual template editor, viewport and crop controls, light/dark mode and timezone settings, batch generation, dynamic Open Graph image automation, and organization-level storage destinations for Amazon S3, Cloudflare R2, Google Cloud Storage, and S3-compatible providers. Scoped API keys, roles, and OAuth-based MCP connections govern access.
HCTI is aimed at developers, designers, and operators working in shared organizations. Plans apply to the organization rather than individual seats, with no per-seat charges for collaborators. A free plan includes a monthly image allowance, and paid plans scale by monthly image volume.
