Gatecheck checker

The checker runs in your browser and needs JavaScript. Files are read on your computer and never uploaded.

Drop images (JPG, PNG, GIF, WebP), video (MP4, MOV including ProRes, M4V, WebM) or HTML5 zips, and Gatecheck checks each file against 24 placements on Meta, TikTok, YouTube, Google Ads, Campaign Manager 360, Display & Video 360, LinkedIn, Snapchat, X, Pinterest, connected TV and TV broadcast. It tells you what will be rejected, why, and how to fix it. One file at a time is free; Pro checks a whole campaign against a delivery plan.
