HTML to JPG API Overview

Convert HTML/HTM files to JPG screenshots using a modern headless browser renderer. Control image width/height, JPEG quality, zoom level, and crop by CSS selector or coordinates for pixel‑accurate results. Customize page loading with timeouts, delays, and wait‑for‑element; run page JavaScript; inject custom CSS/JS; block ads and cookie banners; hide elements; and set headers, cookies, and basic auth. Ideal for thumbnails, previews, reports, and archiving consistent page renders.
