Cloudmersive Document and Data Conversion vs Rendex
Cloudmersive's Convert API turns web pages and HTML into PDF or PNG screenshots, transforms Word/Excel/PowerPoint files into PDF and other office formats, and reformats images across 100+ file types including HEIC, PSD, and TIFF. It sits inside Cloudmersive's broader multi-API platform under a single API key, with a free tier of 600 calls/month that never expires.
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.
