How to expand a picture in Photoshop with 4 proven methods

Adobe Photoshop is a powerful image editing and design software used worldwide. When it comes to expanding backgrounds in Photoshop, there are four powerful tools with distinctive features: Content-Aware Scale excels at stretching backgrounds without distorting subjects, while Content-Aware Fill is perfect for seamlessly filling new canvas areas. The Clone Stamp Tool offers precise manual control for detailed expansions, and the new Generative Fill leverages AI for intelligent background extensions. Let's explore each method to help you choose the right technique for your specific needs.



Method 1: How to expand an image in Photoshop using Content-Aware Scale

Content-Aware Scale is Photoshop's smart resizing tool that intelligently stretches backgrounds while preserving important subjects. This method works best for images with simple backgrounds and clearly defined subjects, making it ideal for landscape photos or product shots that need extra space.

Step
1. Prepare your canvas
2. Begin by opening your image in Photoshop. Go to File and select Open. If your layer is locked, double-click it to convert it to a regular layer.
3. 

   

4. Then, expand your canvas size by clicking on C to get to the Crop tool. Hold "Alt" (or Option on Mac) to expand the canvas. Press Enter to accept the changes.
5. 

   

Step
6. Select Content-Aware Scale
7. Go to Edit and select Content-Aware Scale. Before applying the Content-Aware Scale, make sure you protect your main subject by selecting it with the Lasso tool and using it to highlight (or draw over) the main subject. On the layer's panel, click on Channels, then the layer mask icon to add a new channel (Alpha 1). Finally, click on "Ctrl + D" (Windows) or "Cmd + D" (Mac) to deselect.
8. 

   

Step
9. Stretch the background
10. Click and drag the handles on your image to expand it to fill the new canvas area. Hold Shift while dragging to constrain the scaling horizontally, and hold Alt (Option on Mac) to scale from the center. Photoshop will analyze the image and intelligently expand only the background while keeping the main subject intact. For best results, stretch gradually and in small increments.
11. 

    

Step
12. Refine and save
13. Once you've achieved your desired expansion, press Enter to apply the changes. If needed, use the Clone Stamp tool to touch up any areas that look stretched or unnatural. Finally, save your work by going to File > Save As to save the edited image to your computer.
14. 

    

Method 2: How to expand image in Photoshop with Content-Aware Fill

Content-Aware Fill is one of Photoshop's most powerful tools for expanding backgrounds naturally. It analyzes your image's patterns and textures to generate new content that seamlessly blends with the original background. This method is particularly effective for images with complex textures like grass, clouds, or water.

Step
1. Expand your canvas
2. Start by opening your image and unlocking the background layer—double-click on the layer to unlock it. Next, press C to activate the Crop Tool and set the dimensions for your desired extension. To expand the canvas, hold down the Alt key (or Option key on Mac) and drag the edges outward. This will expand the canvas in a balanced way, creating space for your expanded background.
3. 

   

Step
4. Select the empty area
5. Now, hold Ctrl or Cmd and click on the image in your layer. This selects the image you uploaded, to select the empty area instead, hold Ctrl + Shift + I or Cmd + Shift + I.
6. 

   

7. Now, to ensure a smooth blend, head to Select > Modify > Expand. Expanding by 5 or 10 pixels should be fine. This is an important step because it allows the border lines to dig in a bit into the image, which prevents border lines after expansion.
8. 

   

Step
9. Apply Content-Aware Fill
10. Next, click Edit, then Content Aware Fill. Photoshop will analyze the image and fill in the empty space in a few seconds or minutes (depending on how large your image is). Once it expands the image, click OK to apply the changes.
11. 

    

Step
12. Refine and export
13. Check the filled area for any inconsistencies. If needed, use the Clone Stamp tool to touch up any areas that don't look natural. Once you're satisfied with the result, save your expanded image by going to File and selecting Save As to download the edited image to your computer.
14. 

    

Method 3: How to expand picture in Photoshop using the Clone Stamp Tool

The Clone Stamp Tool provides precise manual control over background expansion, making it perfect for images with intricate details or patterns that need careful replication. While more time-consuming than automated methods, it offers unmatched accuracy for professional-quality results.

Step
1. Prepare your workspace
2. Start with uploading your picture to Photoshop. To do that, click File > Open and select the photo you want to expand. Alternatively, you can also drag and drop your photo to upload it.
3. 

   

4. Next, expand your canvas. You can do that by clicking on the crop tool in the toolbar. Now, drag the edges of your photo to the left or right to extend the canvas to the left or right. If you need to expand both sides simultaneously, hold down the Alt key (or Option key on Mac) and drag the edges outward.
5. 

   

Step
6. Use the Clone Stamp Tool
7. Select the Clone Stamp Tool (S) from the toolbar. Hold Alt (Windows) or Option (Mac) and click to sample an area of the existing background you want to replicate. Adjust your brush size and hardness in the options bar for optimal results.
8. 

   

Step
9. Clone the background
10. Begin painting (i.e., right-click and drag) over the canvas area you want to expand the background to. Work in small sections and frequently resample different areas to maintain natural variation. Pay special attention to matching patterns and lighting at the seams.
11. 

    

Step
12. Blend and save
13. Use a softer brush around the edges to blend the cloned areas seamlessly with the original background. Once you're satisfied with the expansion, save your work through File > Save As.
14. 

    

Method 4: How to expand photo in Photoshop with Generative Fill

Generative Fill is Photoshop's newest AI-powered feature, revolutionizing how we expand backgrounds. Understanding your image's context and content can intelligently create new background elements that match your existing image seamlessly. This method is ideal for almost any type of image, especially when you need creative or complex background extensions.

Step
1. Access Generative Fill
2. Start with uploading your picture to Photoshop. To do that, click File > Open and select the photo you want to expand. Make sure your image layer is unlocked; if not, click on the lock icon beside your image in the layer panel.
3. 

   

Step
4. Select and describe
5. Now, click on the Crop tool, then hold Alt (Windows) or Option (Mac) key then drag from the edge to expand the space around the canvas.
6. 

   

7. Now, hold Ctrl or Cmd and click on the image in your layer. This selects the image you uploaded, to select the empty area instead, click Ctrl + Shift + I or Cmd + Shift + I.
8. 

   

9. Next, click on the "Generative Fill" and write in your prompt. For example, you can write: "Expand the background."
10. 

    

Step
11. Generate and review
12. Once you are done adding your prompt, click on "Generate" and watch as Photoshop's AI creates new content to fill your selection. The tool will generate multiple variations for you to choose from. Look through them to find one that perfectly matches your vision. If you don't like the creation, you can regenerate the expansion by clicking "Generate" again.
13. 

    

Step
14. Refine and export
15. If needed, make minor adjustments using the Clone Stamp tool or Spot Healing Brush. Once you're satisfied with the expansion, save your work by going to File > Save As and choosing your preferred format.
