How to Expand an Image in Photoshop with Generative Expand
In this tutorial, you’ll expand an image’s canvas and seamlessly fill the new space using Photoshop’s Generative Expand. This is perfect for reframing a subject or extending a background without manual cloning. You’ll use the Crop tool, generate fills, and pick the best variation.
Step-by-step instructions
Open your image and select the Crop tool
Go to File → Open and select your image.
Select the Crop Tool (C) from the toolbar.
Extend the canvas to reframe your subject
Drag a crop handle outward on the side you want to extend (e.g., right) until your subject is centered.
Check that the newly added area shows as empty/black space outside the original image.
Generate the extended background
In the contextual bar/options, click Generative Expand.
Optionally type a brief prompt, or leave it blank for an automatic match.
Click Generate and wait while Photoshop synthesizes the missing background.
Review variations and commit the result
In the Properties panel, click through the generated variations to preview different fills.
Select your preferred variation.
Press Enter/Return or click the checkmark to commit the crop.
Save your expanded image
Go to File → Save As.
Choose a format (e.g., JPEG, PNG, PSD), name the file, and click Save.
