About this tool
Overlay the UI safe zones for Reels, Shorts and TikTok on your vertical video.
The Vertical Video Safe-Zone Previewer overlays a 9:16 frame with dashed top and bottom boundary guides so you can see which parts of a Reel, Short or TikTok will sit under the platform's own interface. Load a reference frame or clip from your device, position it against the guides, write your review notes, and export the whole review as a plain-text report. It is a visual staging aid for creators and editors, not a scraper of platform layout specs — the guides are yours to adjust against a real platform preview before you publish.
Open Vertical Video Safe-Zone Previewer on AltFTool — it loads instantly in your browser.
Choose a still or clip with the "Optional reference image/video" file picker, which accepts image/* and video/* and renders it from a local object URL that is never uploaded.
Judge it inside the 9:16 preview box against the dashed "Top safe-zone boundary" and "Caption / controls obstruction review" guides, and write each boundary call into "Content and review notes".
Press "Export review report" to download altftool-vertical-video-safe-zone-previewer.txt — the tool name, an ISO timestamp, your notes, and a reminder to re-check every safe-zone assumption in the platform's own upload preview.
Your reference image or video sits inside a true 9:16 box, so what you judge is the shape the platform actually plays.
Every boundary call you type is exported as a dated plain-text report you can attach to the edit ticket.
The overlay is a fixed 9:16 review aid and says so, instead of hard-coding pixel margins that platforms change without notice.
It is the part of a 9:16 frame that no platform interface covers — usually the middle band, with the top status area and the lower caption, handle and action-button strip at risk. Anything you need a viewer to read, such as a price, a caption or a logo, belongs inside that middle band.
No, and that is deliberate. The overlay gives you a fixed 9:16 frame with top and bottom boundary guides you compare your footage against; each platform moves its interface between app versions, so confirm your final placement in that app's own upload preview before publishing.
No. The reference image or clip you select is rendered in your browser from a local object URL and never leaves the device, and the review report is generated and downloaded locally.
A plain-text report containing the tool name, an ISO timestamp, your typed review notes, and a reminder to verify every safe-zone assumption against a real platform preview — suitable for pasting into an edit ticket or handover doc.
