AI Image Extender

Expand the canvas of any image endlessly. PromeAI’s advanced "Outpainting" technology analyzes your photo’s context and intelligently generates new pixels to extend the background, scenery, or details. Convert a vertical shot to horizontal, fix a bad crop, or resize images for social media without stretching or losing quality.

Infinite Canvas Possibilities

Don't let the frame limit your creativity. Expand your vision with AI.

Smart Context Awareness

The AI understands the content of your original image—whether it’s a texture, a landscape, or a lighting pattern. It generates new sections that blend perfectly with the existing pixels, making the extension look like it was part of the original shot.

Aspect Ratio Adaptation

Repurpose your content for any platform instantly. Turn a square Instagram photo (1:1) into a wide YouTube thumbnail (16:9) or a vertical TikTok video cover (9:16). The AI fills the empty space with coherent visuals, saving you from cropping out important details.

Text-Guided Extension

You control what gets added. Leave the prompt empty for the AI to guess the background naturally, or input a specific text prompt (e.g., "add a mountain range," "extend the table") to guide the generation of new elements in the expanded area.
