Html2PDF vs Rendex
Html2pdf.app renders either a live URL or a raw HTML snippet into a downloadable PDF, aiming for pixel-accurate reproduction of modern CSS layouts with configurable page orientation and paper size. Requests are authenticated with an API key in a custom header, and the service runs on a monthly credit system charged per megabyte of generated output rather than per request.
Rendex runs headless Chromium across a global edge network to turn live URLs, raw HTML, or Markdown into pixel-perfect PNG, JPEG, WebP, or PDF output, including full-page scroll-stitched captures. It also supports templated batch jobs across many URLs at once and HMAC-signed webhook callbacks, on a metered free tier with paid plans billed per rendering call.
