Bring in
your HTML.
Import an HTML file with its images, fonts and scripts, or paste the code straight into the studio. Libraries loaded from a CDN, such as GSAP or Three.js, work as they do in the browser.
HTML TO MP4 CONVERTER FOR WINDOWS
Convert HTML to MP4
on your own PC.
Turn an HTML, CSS or JavaScript animation into a smooth MP4 video in HD or 4K. Rendered frame by frame, without screen recording and without uploading your files.
How to convert HTML to MP4 in three steps
Bring in
Check every
frame.
Scrub the live preview, set the length on the timeline and choose the size: 1920 × 1080, 3840 × 2160 for 4K, vertical 9:16 or square.
Export
the MP4.
Choose MP4 (H.264) and click Render Video. The studio renders each frame itself, so the timing is exact, and supported NVIDIA graphics cards speed up the encoding.
MOV, WebM
or PNG frames.
Need something else? The same project exports to MOV or WebM, or to a PNG sequence for editing in another video app.
Why not a screen recorder or an online converter?

| Your files | Stay on your PC | Stay on your PC | Uploaded to a server |
| Video length | No time limit | No limit | Usually short limits |
| Edit before export | Preview, timeline, sizes | No | No |
Tips for a clean MP4
- Size the page to the video. Design for 1920 × 1080 (or 3840 × 2160) and keep
body{margin:0;overflow:hidden}, so nothing scrolls or crops. - Test a short range first. Set In and Out points around two seconds and render a test before a long export.
- Use 30 or 60 fps. 30 fps suits most social video; 60 fps makes fast motion smoother. The studio goes up to 120 fps.
- Add the sound in the studio. Music or a voiceover on the timeline is mixed into the MP4, with fades and trimming.
HTML to MP4 questions
Does it work with CSS, GSAP and canvas animations?
Yes. CSS keyframes and transitions, GSAP timelines, canvas, SVG, Three.js and WebGL all render to MP4. For full control, a page can add a renderFrame hook to draw each frame at an exact time.
Can I export HTML to MP4 in 4K?
Yes. Pick 3840 × 2160, or set any custom size up to 8K. The video is rendered at that size directly, so it does not depend on your monitor.
Is there an online version?
No. HTML TO MOTION is a Windows desktop app from the Microsoft Store. Rendering on your own PC means no uploads, no queue and no length limits.
