What This Tool Is For

🖼️

Uncrop Images

Recover space around portraits, products, and compositions that feel too tight.

↔️

Extend the Canvas

Add natural-looking background on the left, right, top, or bottom.

📐

Change Aspect Ratio

Turn a square image into a wide banner or vertical story format.

🎨

AI Outpainting

Generate believable edges instead of stretching or cloning the original pixels.

Image Expander vs Upscaler vs Background Changer

These three tools sound similar, but the user intent is different. Image Expander adds space around the current frame. Upscaler increases resolution. Background Changer swaps the scene behind the subject.

Image Expander

Adds new visual area around the photo

Image Upscaler

Makes the image larger and sharper

Background Changer

Replaces the current background with a new one

Best Use Cases

📱

Turn 1:1 into 16:9

Expand square social images into YouTube thumbnails, banners, and ads.

👤

Uncrop Portraits

Add headroom, shoulder room, or negative space for profile and hero images.

🛒

Product Layouts

Give products more margin so pricing, labels, or CTA text fit cleanly.

🖥️

Hero Banners

Extend scenes to fit website headers and landing page hero sections.

FAQ

What is AI outpainting?

AI outpainting extends an image beyond its original borders by generating new pixels that match the existing scene, perspective, and lighting.

How is this different from upscaling?

Upscaling increases the resolution of the current image. Expanding adds new space around the image. You often use expander first, then upscale if you need a larger final export.

Can I expand just one side?

Yes. You can ask for more room on one side only, such as “add background on the left for ad copy” or “extend the sky upward.”

Will the subject stay centered?

Usually yes if you ask for it. Prompts like “keep the subject unchanged and extend the background around it” help preserve the original composition.
