Good to know
- TikTok's Help Center didn't load for us, so the limits for a video posted from the app are not on this page; only the ads and API figures are.
- TikTok publishes its safe zone as template images, not numbers. The safe-zone checker draws what its buttons and caption cover over your own video.
