How do I convert HTML to video? Open the app, paste or load your HTML/CSS, then click Generate Video. When rendering finishes, click the download button to save the MP4.
Where is the video saved? You choose the location in the standard macOS save dialog (it defaults to your Downloads folder). HTML2MP4 only writes to the location you pick.
Does it need an internet connection? No. All rendering and video encoding run locally on your Mac. The app makes no network calls to convert your content.
Which output format do I get? MP4 where your Mac’s encoder supports it, with an automatic WebM fallback on older systems.
What are the system requirements? macOS 12 (Monterey) or later, Apple Silicon.
Is there a subscription or account? No. HTML2MP4 has no account, no subscription, and no in-app purchases.
