How to turn a ChatGPT HTML animation into a video

Ask for runnable HTML, not just an idea

Request the complete file with inline styles and scripts. A canvas animation is easier to export directly than a page composed of animated DOM elements. If you receive a multi-file project, ask for a standalone HTML version or package the required assets yourself; ZIP import is not supported.

The converter does not open ChatGPT conversation links, generate animations, or capture a ChatGPT interface. Save the actual HTML source and check that it works before importing.

Write a complete, standalone HTML file for a looping canvas animation.
Use inline CSS and JavaScript with no external requests.
Use a 720 × 720 canvas and a 10-second loop.
Animate with requestAnimationFrame. Return runnable HTML source.

Choose the right capture method

For a canvas animation, import your file and select Canvas animation. The converter captures the chosen canvas and fits it into your output dimensions without resizing its backing store.

For DOM/CSS motion, choose Tab recording and open the playback tab. When you create the video, use the browser's sharing dialog to select that tab. Screen/window selections are rejected. Make sure the selected tab shows only the intended animation.

Create a shareable output

1. Open the converter and import your saved .html file. Wait for Preview ready and review any warnings.
2. Choose a square, vertical, or landscape output. Set the duration to match the motion you want to capture.
3. Use Mute or add a local soundtrack with Replace audio. Original audio requires tab recording and an actual shared tab-audio track.
4. Select a supported output format and create the video. Keep the recording visible and avoid heavy work while capturing.
5. Play the exported file to check timing, framing, and sound before downloading or sharing it.

Know what stays local

Your imported HTML and audio are processed in browser memory. They are not uploaded to the application server or saved to localStorage. The application itself is downloaded from the server, and enabling external resources lets the imported HTML contact third parties.

The preview is sandboxed, but arbitrary HTML remains active code. Use trusted sources. An iframe does not provide complete protection against malicious self-navigation or an infinite loop.

A real canvas export

This four-second silent MP4 was created with this converter from the downloadable canvas sample at 720 × 1280. Try the same source before importing your own animation.
