HTML to PNG Python Overview
Convert HTML/HTM files to PNG screenshots using a modern headless browser renderer. Control output width/height, zoom level, and crop by CSS selector or coordinates; optionally use a transparent background for overlays. Customize 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. Great for crisp, lossless thumbnails, previews, and documentation.
