wkhtmltoimage

Headless command-line tool (and C library) that renders HTML into image files using the Qt WebKit rendering engine, without requiring a display server or window manager — useful for automated screenshot/thumbnail pipelines running on a server. Can capture live URLs or local HTML files, applying the same CSS/JavaScript rendering a real browser would. Shares its rendering engine and codebase with the companion wkhtmltopdf; both are archived and unmaintained, since Qt WebKit itself was deprecated in favor of Chromium-based headless rendering.
