Ad Spec Checker
Drop your creative and instantly see if it passes specs for every major ad platform.
Every major platform, TikTok, Instagram Reels, Facebook, YouTube, LinkedIn - enforces its own aspect ratio, resolution, codec, maximum file size, and duration limits. A creative that passes review on Meta can be rejected by TikTok for being 1:1 instead of 9:16, or by YouTube for exceeding the 256 GB container cap. Spec failures are the single most common reason launches slip past their scheduled go-live.
Performance marketers and creative ops teams use a spec checker before any upload to catch aspect-ratio safe-zone violations, under-size resolutions that trigger ugly upscaling, and over-weight files that burn CDN bandwidth. Running through all five placement sheets manually takes 15 minutes per asset; this tool returns a per-platform pass/fail matrix in under a second using only the file metadata your browser already reads.
Get specs wrong and you either get rejected outright, or the platform auto-crops the logo, CTA, or end card out of frame, quietly tanking brand-lift and CTR without any error to tell you why. Validating before upload is the cheapest thing you can do to protect your creative.
