Why It Matters

Every platform has different requirements for ad creatives. A video that works perfectly on YouTube may get rejected by TikTok because of aspect ratio, or hit the file size limit on LinkedIn. Checking specs manually is tedious and error-prone. This tool reads your file's metadata instantly and compares it against the latest requirements for five major ad platforms — so you can catch problems before uploading. No account needed. No file upload to any server. Everything runs locally in your browser.
