Problem
What needed solving
A reliable way to turn browser-native animation into video without screen recording, cloud upload queues, or rebuilding the work in a timeline editor.
Creative Software
HTMLtoMP4
A Windows desktop product for rendering deterministic MP4 and WebM video from HTML, CSS, and JavaScript.
Product story
Why it exists.
HTMLtoMP4 grew from the same HTML-animation practice behind HTMLHub. It turns those browser-native experiments into repeatable video assets for creators, developers, agencies, and automation workflows.
Origin: Turn HTML animation into reusable video without recording the screen or sending private source files to a hosted renderer.
Built to give creators and developers a repeatable local path from browser animation to production-ready video.
Built
What we built
A Windows x64 desktop workflow using bundled Chromium, deterministic animation stepping, frame capture, FFmpeg encoding, NVENC acceleration, and CPU fallback.
Outcome
What exists now
A shipping local renderer with a free trial, real application captures, batch controls, and documented output up to 4K at 60fps.

- 01 The product page shows real Windows trial screens for selection, encoder detection, progress, completion, and output.
- 02 A public comparison shows a live HTMLHub animation beside the H.264 MP4 rendered from the same HTML.
- 03 The downloadable trial documents 10 local renders, 1080p output, 10-second duration, and one-file-at-a-time limits.
