How to turn CSS animation into an MP4

Fill the form above — Sign in when you create (or the HTML form). New accounts get 3 free credits to try a render (not unlimited free usage).
Paste your CSS-animated HTML — Include the markup plus the stylesheet (or inline styles) that define @keyframes, animation properties, or WAAPI-driven motion. Or click Try a CSS sample for a minimal keyframes starter (fill only — it never auto-submits). Optional notes: “keep easing, export 9:16, hold final CTA 1s.”
Pick format and length — 16:9, 1:1, 4:5, or 9:16; about 6–30 seconds. Submit; when the job finishes, download the H.264 MP4.

Real output: HTML composition rendered frame-by-frame to MP4 — same engine as the HTML form.

Who this page is for

People searching css animation to video already have motion written in CSS — hero fades, UI micro-interactions, WAAPI timelines — and need a file for ads, social, or a deck. This page stays CSS-first; it is not the full GSAP/HyperFrames tour.

Front-end designers — Ship @keyframes mock motion as MP4 without rebuilding in After Effects.
Product and growth marketers — Turn landing-page CSS loops into Reels/Shorts that match the live site.
Agencies — Deliver client CSS animations as video without recording every laptop at different frame rates.
Design-system authors — Export documented motion tokens as shareable clips for stakeholders who do not open DevTools.

Mixing GSAP or full HyperFrames compositions? Prefer the sibling HTML animation to video guide. No animation yet? Start from a brief with prompt to video, a live URL with website to video, or brand lines with brand kit video. Engine overview: what is HyperFrames?

CSS-first vs broader HTML animation export

Html2MP4’s hosted HTML → MP4 path is the same product. The difference is the animation techniques you want to use:

This page (CSS animation to video) — @keyframes, CSS transitions, WAAPI, and tips for making CSS motion export cleanly.
HTML animation to video — Broader CSS + GSAP + HyperFrames compositions and when seekable timelines beat screen recording.
Convert HTML to video — General “paste HTML → MP4” convert intent, animated or not.
Render HTML to MP4 — Pipeline and export reliability (why a frame looks wrong).

CSS animation render vs screen recording

Recording a browser tab is the usual workaround: open the page, hit record, hope the GPU keeps up. Fine for a one-off demo; weak for batch ads and brand-consistent timing.

Frame-accurate server render — Html2MP4 uses HyperFrames + FFmpeg so each frame samples a known time on the timeline.
Stable aspect ratios — Choose 16:9 / 1:1 / 4:5 / 9:16 up front instead of cropping a desktop capture later.
No “laptop speed” variance — Recording on a slow machine drops frames; seekable render does not depend on your fan noise.
Honest limits — Hover-only interactions, infinite non-seekable loops, and login-walled pages are harder. Prefer motion driven by time (animation-duration, WAAPI currentTime), not by mouse position.

For how the hosted pipeline encodes frames, see render HTML to MP4. Local CLI tips: HyperFrames render troubleshooting.

What you get

Each successful job returns a downloadable H.264 MP4 of your CSS-animated HTML. Before create you choose:

Landscape 16:9 — YouTube, site embeds, decks.
Square 1:1 — Feed posts.
Portrait 4:5 — Instagram feed.
Vertical 9:16 — Reels, Stories, Shorts, TikTok.

Cost is 1 credit per successful render. System failures return the credit. Html2MP4 is not a timeline NLE and not a browser recorder: you submit HTML/CSS source, the server renders, you download. Packs live on Pricing — this page stays focused on CSS export, not selling plans.

Tips for clean CSS → MP4 exports

Prefer time-driven keyframes — Finite durations you can scrub beat infinite loops that never settle. WAAPI with a controllable timeline is similarly strong.
Paste complete CSS — Missing keyframes or fonts make the agent guess; include the styles the animation needs.
Declare the end state — Notes like “hold final CTA 1s” reduce awkward cutoffs mid-easing.
Match the channel — Design 9:16 compositions for Reels; do not stretch a 16:9 hero and hope.
Avoid pointer-only demos — Hover and drag interactions do not play the same way in a headless frame render.
One job at a time while learning — Judge the first export before batching variants.
Local CLI option — Unlimited experiments on your machine: install HyperFrames. Use the form above when you want zero local FFmpeg.

Common questions

What does CSS animation to video mean on Html2MP4?

You paste HTML that uses CSS @keyframes, transitions, or the Web Animations API (WAAPI). Html2MP4 renders that motion frame-by-frame into a downloadable H.264 MP4 — not a live browser screen capture.

How is this different from HTML animation to video?

Same hosted HTML → MP4 product. This page is CSS-first (@keyframes / WAAPI). The HTML animation to video guide covers broader CSS + GSAP + HyperFrames compositions. Paste on this page or open /.

Do @keyframes and WAAPI export reliably?

They work best when motion is time-driven and seekable — duration, delay, and iteration you can scrub. Infinite non-seekable loops and pointer-only hover tricks are harder. HyperFrames seekable timelines remain the most reliable path.

Why not screen-record a CSS animation?

Screen recording depends on your laptop’s frame rate and CPU load. Dropped frames and uneven easing are common. Frame-accurate HyperFrames render samples known times on the timeline, so timing stays consistent across exports.

How do I export CSS animation to MP4 online?

Paste your HTML with the CSS that drives the motion (or click Try a CSS sample for a short keyframes starter — fill only, never auto-submits), add notes such as aspect ratio and end state, pick length, then create. When the job finishes, download the MP4. New accounts get 3 free credits to try.

What formats and lengths can I export?

Landscape 16:9, square 1:1, portrait 4:5, and vertical 9:16, about 6–30 seconds for the HTML tab.

What if my CSS animation looks wrong after render?

Paste complete stylesheets (including fonts and keyframes), prefer time-based animation over hover-only demos, and note the intended end frame. For pipeline details see render HTML to MP4; for local CLI issues see HyperFrames render troubleshooting. Hosted failures return the credit; email contact@html2mp4.com if something looks wrong.

Is there a CSS animation template I can start from?

Yes. The CSS text reveal official pack is a curated CSS/HTML headline animation. Open it from Examples / Templates on this page or /video-templates/ (Templates tab) with that pack selected, fill fields, and enqueue. You can still paste your own @keyframes HTML on this page.
