Preview Reels, Shorts and TikTok safe zones so captions and text never get covered by platform UI — plus 1:1 and 4:5 feed post overlays.
Drag a video frame or thumbnail here to preview overlays (optional)
Red zones — where each platform's own UI (like buttons, caption text, profile icon, progress bar) usually overlaps your video, so avoid placing key text or faces there.
Green box — the safe zone: keep your subject, captions, and CTAs inside this area so nothing gets covered on any device.
Overlay positions are based on typical published UI guidelines for Reels, Shorts, and TikTok and are a planning aid — always preview inside the actual app before publishing. All processing is 100% local; nothing is uploaded.
Safe-Zone / Aspect Ratio Preview overlays each platform's typical UI zones (profile icon, caption text, action buttons, progress bar) onto a 9:16 frame for Reels, Shorts and TikTok, or a 1:1 / 4:5 frame for feed posts — so creators can check that important text, faces or CTAs stay inside the visible 'safe zone' before publishing.
Pick a platform
Choose Reels, Shorts, TikTok, or a square/portrait feed post.
Upload a frame (optional)
Drag in a thumbnail or exported frame from your video to preview against.
Check the overlay
Keep key text and subjects inside the green safe zone, away from the red UI-overlap zones.
