Free HTML to MP4 Converter for AI-Generated HTML

This free HTML to MP4 converter turns pasted or uploaded HTML into MP4 video directly in the browser. It is made for AI-generated HTML, animated HTML reels, prototype pages, and visual snippets that need to become video without spending more AI tokens on conversion.

Use it when an AI tool gives you HTML, CSS, and JavaScript for a motion graphic, social reel, landing-page animation, carousel preview, or visual demo. The app renders the HTML locally, records frames, encodes MP4 with FFmpeg WebAssembly, and can upscale output to 2x or 4x.
