You add a caption to a vertical video, post it, and the app covers it: the like and share buttons down the right, the username and description along the bottom, a search bar at the top. Every platform hides a different part of the frame. The area that stays clear is the safe zone.
Drop a frame or a screenshot of your video and this tool lays each app's interface over it: TikTok, Instagram Reels, YouTube Shorts and Stories. Areas in red are covered; keep titles, subtitles, faces and logos out of them. Switch between platforms to find a placement that survives all of them if you post the same video everywhere, and download the preview to share with whoever edits your videos.
The image is checked on your device and not uploaded. One honest caveat: apps move their buttons from time to time and phones differ in shape, so treat the zones as a margin to stay well inside of, not a line to touch.

Frequently asked questions
- What is a safe zone?
- The part of your vertical video that ISN'T hidden behind the app's like/comment/caption UI. Keep your text there.
- Which platforms are covered?
- TikTok, Instagram Reels, YouTube Shorts and Stories — switch between them to compare.
- Where is it safest to put text?
- The middle of the frame, slightly above centre. The bottom quarter and the right edge are the areas most often covered.
- Can one video work on every platform?
- Yes, if the important elements sit inside the area that is clear on all of them. Check each platform here and place your text where none of the overlays reach.
