## What it is
Takumi is a Rust-based rendering engine that converts JSX, HTML, and CSS into images (PNG, JPEG, WebP, SVG, animated GIF/WebP) and paged PDFs without a headless browser. It ships as native Rust bindings for Node.js and WebAssembly for edge runtimes like Cloudflare Workers, Vercel Edge, Deno, and browsers.

## Use cases
- generate Open Graph images for blog posts and social media cards
- render social preview images in Next.js as a drop-in replacement for next/og
- generate invoices and paged PDF documents from JSX templates
- render animated WebP or GIF banners from CSS keyframes
- generate OG images on Cloudflare Workers or edge runtimes without Chromium
- convert HTML and CSS layouts to images without a headless browser
- produce SVG and raster outputs from a single component tree

## When to choose
- you need OG images or social cards on serverless/edge platforms where headless Chromium is too heavy or unavailable
- you want fast, low-memory image or PDF generation from JSX/HTML/CSS without launching a browser
- you need animated image outputs (GIF, WebP, APNG) rendered from CSS animations
- you want a satori or puppeteer alternative with a compatible ImageResponse-style API

## When to avoid
- you need pixel-perfect rendering of complex real-world web pages with full browser fidelity
- you rely on browser-specific features like JavaScript execution inside the rendered page or full iframe support
- you need to screenshot existing live websites rather than render your own markup
