Instagram Story & Reels Cover Generator with AI (1080×1920)

AI-generate vertical 1080×1920 Instagram Story and Reels cover thumbnails. Upload a photo, describe the mood, export PNG, JPG or WebP for free.

Stories and Reels live and die by the first frame. This guide shows how to generate a 9:16 vertical cover with AI, keep your headline inside Instagram's safe zone, and export a clean 1080×1920 PNG that won't get cropped by the top and bottom UI overlays.

The 9:16 safe zone

Instagram reserves roughly the top 250 px (profile, timer) and the bottom 250 px (caption, actions) on Stories and Reels. Anything critical — the face, the headline, the CTA — should sit inside the middle 1080×1420 window. The Thumbnail Generator's guides make it easy to keep text in the safe zone.

Step-by-step

  1. Upload a portrait-orientation reference photo.
  2. Pick the Instagram Story preset (1080×1920).
  3. Prompt idea: ‘tall vertical composition, subject centered, soft gradient background, room for headline at top-center’.
  4. Generate, add a short vertical-friendly headline (3–5 words).
  5. Add a brand logo in the top-left inside the safe zone.
  6. Export PNG for the sharpest edges or WebP for smaller files.
