iLovePDF vs Rendex
The developer platform behind iLovePDF has been rebranded iLoveAPI, offering a REST toolkit for manipulating PDFs (merge, split, compress, convert, encrypt, add page numbers) plus editing images in formats like JPG, PNG, HEIC, and WEBP. Authentication exchanges a public/secret key pair for a short-lived JWT bearer token, and new accounts get 2,500 free credits per month before usage-based billing kicks in.
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.
