Frequently Asked Questions
What are the recommended Instagram image sizes?
Square posts: 1:1 (1080×1080px). Portrait posts: 4:5 (1080×1350px). Stories and Reels: 9:16 (1080×1920px). AI Image Extender supports all of these ratios.
How is AI expansion different from just cropping?
Cropping removes content from your original image. AI expansion extends the background outward to change the ratio, keeping all your original content while naturally filling the new areas.
What types of Instagram content work best?
Portraits, landscapes, product shots, food photography — all work well. The AI analyzes your image and generates a matching background extension.
Can I use this for Instagram Reels covers?
Yes. Instagram Reels covers use the 9:16 ratio (1080×1920px). Upload your image, select 9:16, and the AI extends it to the perfect Reels cover size — keeping your original content with a natural background extension.
What if I'm not happy with the result?
Each generation produces a different result — just try again. You can also adjust the extension direction for better outcomes.
