Questions
- What is a safe zone on TikTok or Reels?
- The safe zone is the part of a vertical video that the app's interface doesn't cover. The username, caption, music, and the action buttons (like, comment, share) sit on top of your footage — so any text or important visuals placed there get hidden. Keeping key elements inside the safe zone makes sure viewers can actually read and see them.
- What is the correct aspect ratio for short-form video?
- 9:16 — a vertical frame, typically 1080 × 1920 pixels. TikTok, Instagram Reels, and YouTube Shorts all use it full-screen. If your image or video isn't 9:16, the app crops or letterboxes it; this tool shows you exactly what gets cut.
- Where do the TikTok, Reels, and Shorts buttons sit?
- All three stack their action buttons down the right side and put captions, username, and audio along the bottom, with a thin bar at the top. The exact heights differ slightly per app, so this tool switches the overlay when you change platform. As a rule, keep text out of the bottom third and the right edge.
- Is my uploaded image stored anywhere?
- No. The image is loaded only in your browser to draw the overlay — it's never uploaded to a server and nothing is saved. Close the tab and it's gone.
- Is this tool free?
- Yes — completely free, no signup, no email. If you want the content inside that safe zone to actually perform, the paid product remixes proven viral scripts into your brand voice.
