Unity Ads export
Unity Ads playable ad specs
The Unity Ads export is one self-contained HTML file up to 5 MB with mraid.js. The game doesn’t start until MRAID reports the ad as ready and viewable, and the store opens through mraid.open().

What’s in the download
Files
your-game-unity.html
your-game is your project title, lowercased with dashes. Everything is inside the file: images as WebP, sounds, 3D models and libraries like three.js or Matter.js. No CDN, no web fonts, no remote URLs.
Added to <head>
<script src="mraid.js"></script>
Plus a start gate. The game waits for MRAID’s ready event and for mraid.isViewable() (or the next viewableChange) before it starts. Nothing in the file locks the orientation. The game resizes to the screen, and QA checks it in portrait and landscape.
How the store opens
The game’s store button calls openStore(). In the Unity Ads export that runs, in order:
- 1mraid.open(storeUrl)
- 2window.open(storeUrl) if MRAID is missing
It only fires from a tap. QA checks that nothing opens the store on a timer, which networks reject.
Over 5 MB?
Images are re-encoded to WebP step by step, from 1024 px at quality 80 down to 512 px at 50, stopping at the first step that fits. If the file is still over 5 MB, it ships as a compressed self-extracting HTML: the game is gzipped inside the file and unpacked by the browser when the ad opens, and the network’s script tags stay outside so its checker still finds them.
What QA checks before you export
The QA agent plays every build in a headless phone browser and checks the package. A build that fails goes back to the developer agent with the fix.
01
Size under the limit
Estimated per network: 5 MB, Meta 2 MB, with a list of what fills the file.
02
Click-out wired, from a tap only
openStore() is bound to the network's call. Networks reject redirects fired by a timer.
03
No external requests
No CDNs, web fonts or remote URLs. Everything the game needs is in the file.
04
Starts when it's seen
The game waits until the ad is ready and visible. Unity requires it.
05
Portrait and landscape
The layout responds to resize and rotation. AppLovin asks for both.
06
Sound starts on tap
No audio before the first touch, so nothing blares from a feed.
