How to Extend a Cropped Photo for a Website Banner Using AI
Extend Image (AI)The Problem
You have a great photo but it was cropped too tightly for use as a website banner, hero image, or social media header. You need more width or height but don't have the original uncropped version — and stretching the image would look terrible.
The Solution
Upload the cropped photo and use SprinkleTools' AI outpainting to extend it in any direction. The AI seamlessly generates new content that matches the original scene — adding sky, landscape, background elements, or whatever naturally continues the image.
How to Do It
Open the Extend Image tool on SprinkleTools
Upload your cropped photo
Choose which sides to extend (left/right for width, top/bottom for height)
Set how many pixels to add on each side (up to 512px per side)
Optionally add a prompt to guide what the AI generates

Frequently Asked Questions
Will the extension look natural?
Yes — the AI analyzes the original image and generates seamless extensions matching the style, lighting, and content.
How much can I extend?
Up to 512 pixels on each side (top, right, bottom, left) — each adjustable independently.
Can I guide what gets generated?
Yes — add an optional text prompt like 'continue the sky and mountains' to guide the AI's output.
What image sizes work best?
The tool works on any image size. Larger original images produce better extensions since the AI has more context.
