What is Fotor AI Image Extender?

Fotor AI Image Extender is a generative tool powered by AI outpainting that expands images beyond their original frames.

Unlike traditional extenders that merely stretch pixels (causing blurriness) or crop edges, Fotor’s AI analyzes lighting, textures, and context to generate brand-new, seamless content. This allows for natural aspect ratio conversions without distorting the subject or losing quality.

Easy, Automatic AI Generative Fill

No manual editing required—simply upload an image, select a preferred ratio, and let AI generate new pixels instantly.

Our AI generative fill algorithms automatically recognize the image context, using intelligent inference and vast datasets to generate a seamless background.

Forget about complex content-aware fill or healing tools. The AI generative expand tool solves your problems in an instant.

Redefine Composition with AI Image Expander

Create expanded compositions while filling in missing areas without losing quality. After selecting your ratio, simply drag your original image within the canvas to fix cramped compositions and refine the layout.

This allows you to adjust the visual balance and keep the focal point exactly where you want it, instantly elevating your photography to a professional level.
