Add up to 60 images or videos, pick one platform and get one sheet: every creative under the overlay with its file name, dimensions, an aspect check against the platform frame and the zone scan result. The free preview shows 3 files. Pro exports carry your agency name and logo from your brand kit instead of AdCheckLab. Everything is processed in your browser.
The checker lays each app's interface over your own creative, so you see what buttons and captions would hide before the file goes live.
Drag in an MP4, MOV, JPG, PNG or WEBP, or paste an image with Cmd+V or Ctrl+V. Any resolution works and the aspect ratio is detected for you.
Choose TikTok, Reels, Stories, Shorts, Snapchat, Pinterest or LinkedIn, or YouTube and TV for 16:9 files. Red marks what the app covers.
Save the frame with the overlay, download the overlay as a PNG, or share a link to the same platform.
Last verified 30 September 2026 against each platform's own ads guide or template.
9:16 files get a Feed and Ads switch above the platform list. Ads add a Sponsored label, a call to action button and a longer caption, so their bottom margin is usually deeper. The Ads overlays use the numbers each platform publishes for advertisers. No platform publishes organic numbers, so the Feed overlays are measured from the apps. Organic Stories work differently: their Feed overlay is a guide built from the Story interface and Meta's Stories guidance, with 250 px at the top and bottom because there is no call to action. If a creative runs both ways, check both.
The checker runs entirely in your browser with the Canvas and File APIs. Your file is never uploaded or stored, so it is safe for unreleased campaigns and work under NDA, and the page keeps working offline once loaded.
It draws a platform's interface margins over your own video or image, so you see which text, logos or faces would sit under buttons or captions.
Any video your browser can play, such as H.264 MP4, MOV or WEBM, and JPG, PNG or WEBP images. ProRes and some HEVC files only play in Safari, so export an H.264 MP4 if one fails.
The Ads overlays follow each platform's own ads guide or template, verified on 30 September 2026 and linked in the specs matrix. The Feed overlays are measured from the apps, and the organic Story overlay is a guide based on the Story interface and Meta's Stories guidance.
Yes. 16:9 gets YouTube, YouTube ads and TV, 1:1 and 4:5 get Instagram feed margins, and other ratios a 10% margin. See the aspect ratio guide.
