HTML5 banner to video in three steps

No screen recording, no editing software, no guesswork. The converter renders your HTML5 ad in a real browser and records it frame by frame.

1
Upload your HTML5 ZIP Drop the same ZIP you'd traffic to an ad platform — Google Web Designer, Adobe Animate, GSAP or hand-coded builds all work.
2
Set the duration Choose how many seconds of the animation to capture — long enough to cover every frame of your creative, including loops.
3
Download the MP4 The HTML5 animation is recorded at its native size and encoded to H.264 MP4 — preview it right on the page, then download.

Why convert HTML5 ads to video?

HTML5 banners are the standard for display advertising — but the moment a creative needs to live anywhere other than an ad server, HTML5 becomes a liability. Social platforms, video ad networks, email clients, and slide decks don't run HTML5 ZIPs. Converting an HTML5 banner ad to video gives you a single MP4 file that plays identically everywhere, with zero hosting, browser, or click-tag dependencies.

Screen-recording a banner by hand produces choppy, mis-sized footage with cursor flashes and dropped frames. This HTML5 to video converter renders the creative in a controlled headless browser and captures every frame at a steady 30fps, so the output is a true, frame-accurate copy of the original HTML5 animation.

What teams use HTML5 to MP4 conversion for

Social & video placements Repurpose display creatives as MP4s for Meta, TikTok, YouTube, LinkedIn and programmatic video slots that don't accept HTML5.
Client approvals Send stakeholders a video they can open on any device — no hosting links, no "it won't load on my phone" replies.
Backup / fallback assets Many DSPs request a video or backup asset alongside the HTML5 build. Generate it in seconds instead of rebuilding in After Effects.
Portfolios & case studies Archive campaigns as videos that will still play in ten years — long after the ad-server hosting is gone.

How the HTML5 to MP4 converter works

Under the hood, your ZIP is unpacked, the primary HTML file is located, and the creative is loaded in a real browser engine at its declared banner size. The animation is captured frame by frame for the duration you choose, then encoded to a broadly compatible H.264 MP4. Because the creative runs exactly as it would in a live placement, everything renders correctly — web fonts, CSS keyframes, Canvas drawing, GSAP timelines, sprite sheets and video elements included.

Want to check the creative before converting? Run it through the free HTML5 banner preview tool first, or use the HTML5 ad validator to catch platform issues. And if you need a lightweight animated image instead of a video, the HTML5 to GIF converter uses the same rendering engine with GIF-specific controls for frame rate and looping.
