TikTok Thumbnail Generator with AI (1080×1920)
Generate 9:16 TikTok cover thumbnails with AI in seconds. Upload a photo, describe the mood, add a bold headline and logo — export PNG, JPG or WebP for free.
TikTok covers get compressed hard and are viewed at tiny sizes on the profile grid. A high-contrast AI-generated cover with a punchy 2–3 word headline is the fastest way to look pro without owning a design suite.
TikTok cover specs
- Cover: 1080×1920 (9:16)
- Grid preview crop: roughly the center 1:1
- Formats: JPG, PNG, WebP
Step-by-step
- Upload a reference frame from your video (or a portrait selfie).
- Select the TikTok preset (1080×1920).
- Prompt: ‘neon-lit vertical scene, subject centered, negative space above head’.
- Generate, add a 2–3 word headline in Impact.
- Preview at the grid crop — TikTok crops the center square for profile view. Keep the subject centered.
- Export PNG or JPG.
Design tips
- Keep the important half in the middle 1080×1080 — that's what the grid shows.
- White text with a 4–6 px black stroke survives TikTok's aggressive compression.
- Skip small type. Anything under 60 px tall on 1080×1920 disappears on the grid.
