# Free TikTok & Instagram Safe Zone Checker > This free safe zone checker previews your video or cover image inside a 9:16 frame with the TikTok and Instagram Reels interface overlaid, so you can see exactly where captions, buttons, and the username will cover your content. Keep your hooks, text, and key visuals inside the clear safe area — it all runs in your browser, with no upload. Runs entirely in your browser — the file never leaves your device, no signup, free. ## How it works 1. Drop in your video or cover image. 2. Choose TikTok, Instagram Reels, or both at once. 3. Make sure your key content sits inside the clear safe area, away from the shaded UI zones. ## FAQ ### What is a TikTok safe zone? A safe zone is the part of a vertical 9:16 video that is not covered by the app's on-screen interface — the caption, username, sound title, like/comment/share buttons, and bottom navigation bar. Keeping your important text, faces, logos, and calls-to-action inside the safe zone makes sure nothing critical gets hidden behind TikTok's UI. ### What are the TikTok and Reels safe zone dimensions? Both TikTok and Instagram Reels use a 1080×1920 (9:16) frame. As a rule of thumb, keep key content out of roughly the top 8%, the bottom ~25% (captions and buttons), and the right edge (the action buttons). This tool overlays those zones for each platform so you do not have to guess the exact pixels — and they shift slightly with each app update, so it shows clearly-labeled approximations. ### Does this work for Instagram Reels and Stories too? Yes. Switch the overlay to Instagram Reels to see its interface zones, or choose “Both” to preview the strictest combined safe area that works on TikTok and Instagram at the same time. ### Is my video uploaded anywhere? No. The preview runs entirely in your browser — your video or image is never uploaded and nothing is stored. You can safely check unpublished content.
