Free ad tools, checked against the platform
Each tool runs in your browser and uploads nothing. The numbers they check against come from the platforms' spec pages, each dated, and match our ad specs pages.

Drop an image or video to see which Facebook, Instagram, TikTok and YouTube placements it fits, and crop an image to any of them.
