AppLovin Ad Preview Tool
Use this free AppLovin ad preview tool to build an approximate mockup of your in-app interstitial, rewarded video and end-card ads before you launch. Upload an image or video, enter your copy, check the crop against an approximate safe-zone guide, and download a review PNG. Nothing leaves your browser.
Focal position moves the crop when using Fill. Fit keeps the whole asset visible with padding. Applied in every format.
Interstitial and rewarded mockups only. It marks the top-right close/skip control area and the bottom end-card/CTA strip this mockup uses. UI and available space vary by device and publisher app. Confirm in the AppLovin advertiser dashboard.
Illustrative only. It fills the “Close in” pill on the interstitial and the reward countdown when the creative is an image. A video sets the rewarded countdown from its own remaining time. The real close delay and reward timing are set by the network and the publisher app.
Locally rendered review mockup, not an exact platform screenshot. Video exports the current paused frame as a still PNG. Guides are included when enabled.
Approximate mockup of a 9:16 phone screen. Overlay positions, timers and the end card are illustrative. No ratings or review counts are shown because this tool cannot verify them.

Why Use an AppLovin Ad Preview Tool?
Review In-App Context
In-app ads render differently from social feed ads. This approximate mockup places your creative behind a full-screen interstitial overlay with a close control, timer and CTA strip, so you can review it in a layout that resembles a mobile app placement. The real overlay varies by publisher app and device.
Compare Three Formats
Interstitial, rewarded video and end card have different user expectations and UI elements. Preview all three to check how your creative sits with the reward pill, countdown, dimmed close control and post-video end card this mockup uses.
Catch Layout Issues
The close control, Ad label and CTA strip overlay your creative. Turn on the approximate safe-zone guide to see where this mockup places them, then confirm the final rendering in the AppLovin advertiser dashboard before going live.
No AppLovin Account Needed
Build the mockup without logging into the AppLovin dashboard. Your images and videos stay in your browser, the PNG export is rendered locally, and the tool is free with no limits. Useful for agencies managing multiple ad networks.
How It Works
Upload Your Creative
Drag and drop an image (JPG, PNG, WebP) or a video (MP4, MOV). Videos play muted and looping. The file stays in your browser. No file handy? Load the locally generated sample creative.
Set the Crop and Copy
Choose Fill or Fit, move the focal position, and enter your app name, headline, body text and call to action. The copy feedback line shows character counts against the thresholds this mockup uses.
Compare Formats and Export
Switch between interstitial, rewarded video and end card, turn on the approximate safe-zone guide, and download a PNG mockup (the current paused frame for video) to share with your designer or client.
Understanding AppLovin Ad Formats
AppLovin is a large in-app advertising platform that serves ads across many mobile apps through its MAX mediation platform and AppDiscovery network. For mobile app marketers, it is a common channel alongside Meta and Google, particularly for gaming, entertainment and utility apps. How much of your budget belongs there is a question for your own campaign data.
Unlike social media platforms where ads appear in content feeds, AppLovin ads appear inside other mobile apps at transition points. This creates a different user context: viewers are not scrolling through content, they are paused between game levels, waiting for content to load, or choosing to watch an ad in exchange for an in-app reward.
Interstitial Ads
Interstitial ads are full-screen ads that appear at transition points within an app. When a user finishes a game level, completes an action, or moves between screens, the interstitial takes over the display. A close control usually appears in the top-right corner after a short delay that is set by the network and the publisher app. The timer in this mockup is an illustrative input, not a measured delay.
The overlay in this mockup includes an "Ad" label in the top-left, a close control with a countdown in the top-right, and a CTA strip at the bottom with your app icon, name, headline, body text and install button. Your creative fills the area behind these elements. Because the ad is full-screen, check that the image or video holds up at phone resolution and that nothing important sits under the overlay.
Rewarded Video Ads
Rewarded video ads are opt-in: users choose to watch an ad in exchange for an in-app reward such as extra lives, virtual currency or premium content. The user has voluntarily engaged with the ad, which changes how the creative is received.
The rewarded mockup adds a reward pill with a countdown and progress bar, and dims the close control. When you upload a video, the countdown tracks the video's remaining time; for an image it uses the illustrative timer input. The real minimum watch time before the reward is granted is set by the network and the publisher app, so confirm it in the AppLovin advertiser dashboard.
At the end of the video, an end card typically appears with your app info and CTA. The end-card mockup shows your creative above an app icon, name, headline, body text and CTA button. It does not show star ratings or review counts because this tool cannot verify them; add only claims you can substantiate in the live creative.
Creative Review Prompts for In-App Ads
In-app advertising has different creative constraints from social media advertising. Use these prompts to review the asset; the mockup cannot predict performance, so measure results with your own campaign data.
Respect the overlay areas. The close control, Ad label and CTA strip occupy fixed positions in this mockup, and similar elements exist in live placements. Keep critical visual elements and text away from these areas, and use the approximate safe-zone guide to check for overlap before launching.
Front-load the value proposition. Interstitials can be dismissed after a short delay, so the opening seconds should communicate what your app does and why the user should care. For rewarded video, users tend to stay longer, but the opening still sets the tone.
Match the context. Users seeing your ad are in the middle of using another app. Gameplay footage, screen recordings and UGC-style content are common choices for this environment; test them against your own alternatives rather than assuming one style wins.
Make the CTA button clear. The CTA at the bottom of the ad is the primary conversion mechanism. Use action-oriented text ("Install Now," "Play Now") and make sure the strip provides enough context (app name and a short headline) for the user to understand what they are installing.
How AppLovin Fits Into Mobile UA
AppLovin's appeal is reach in the gaming and app-install verticals. Through MAX mediation, AppLovin accesses inventory across many ad networks and exchanges, which can extend reach beyond a single social platform. For app marketers already running Meta, Google and TikTok, AppLovin is a common diversification channel.
The platform's optimization (AppDiscovery) uses machine learning to find users likely to install and retain. You can optimize toward installs, ROAS targets or post-install events. One difference from social platforms is that AppLovin optimizes across many app placements, so creative fatigue can behave differently: your ad may appear in different apps across categories.
For gaming apps, AppLovin is often a significant spend channel, and the opt-in nature of rewarded video means viewers have chosen to watch. Completion and conversion rates vary by app, placement and creative; use your own campaign reporting rather than generic benchmarks.
Subscription apps and non-gaming verticals also run on AppLovin. The key is creative clarity: your ad needs to communicate value in a context where users are briefly paused from another activity. Think of it as a short pitch delivered at a transition moment.
Frequently Asked Questions
Is this AppLovin ad preview tool free?
Yes, completely free with no account required. No usage limits, no watermarks, and no hidden fees. Everything runs in your browser.
What ad sizes does this tool use?
The mockup uses a portrait 9:16 phone frame. Portrait and landscape creatives both work: landscape assets are cropped under Fill or padded under Fit. The tool does not validate required dimensions, file size or duration; check the platform's current spec in the AppLovin advertiser dashboard before uploading.
What is the difference between interstitial and rewarded ads?
Interstitial ads appear at transition points and can be dismissed after a short delay set by the network and publisher app. Rewarded ads are opt-in: users choose to watch in exchange for an in-app reward, and the close control is typically unavailable until the reward is earned. How each format performs for you depends on your app, creative and audience.
Are my images or videos uploaded to a server?
No. Your files are read entirely in your browser and the PNG export is rendered locally with the canvas API. Nothing is sent to any server. The file is released from memory when you reset, replace it, or close the page.
Can I preview video or playable ads?
Video, yes: upload an MP4 or MOV and it plays muted and looping inside the interstitial, rewarded and end-card mockups, subject to your browser's codec support. The PNG export captures the current paused frame. HTML5 playable ads and VAST tags are not previewed.
How accurate is this compared to real AppLovin ads?
It is an approximate mockup, not a platform screenshot. It places a close control with timer, Ad label, reward pill, CTA strip and end card in positions typical of in-app ads, but real rendering varies by publisher app, SDK version and device. Use it to review cropping, copy and overlap, then confirm the final ad in the AppLovin advertiser dashboard.
What is AppLovin MAX?
AppLovin MAX is an in-app mediation platform that allows app publishers to serve ads from multiple demand sources (ad networks) through a single SDK. For advertisers, this means your ads can reach users across the apps that use MAX for monetization. MAX runs the auction and serves the highest-paying ad for each impression.
