Image Expander turns an existing image into a new composition with more space around it. Upload one or more images, choose a target aspect ratio, and the tool keeps the original image centered while AI fills the newly added areas.
Use it when you need a widescreen banner from a portrait render, a vertical social post from landscape art, a square thumbnail, an ultrawide environment, or alternate framing for game art, character images, marketing visuals, backgrounds, and concept pieces.
What it does
Image Expander performs AI outpainting: it expands beyond the borders of your uploaded image while trying to match the existing subject, perspective, colors, lighting, and style.
The original image is displayed centered inside the selected target frame. The added space is generated around it, so the preview helps you understand where the new content will appear before you start.
You can guide the expansion with an optional prompt. For example, you can ask for more forest, sky, mountains, studio backdrop, city street, mist, ocean, or other continuation details. If you leave the prompt blank, Image Expander attempts to infer a seamless continuation from the source image.
Generated results appear in the Expanded Images gallery, where you can view, download, delete, and manage recent outputs.

If you are not signed in, Image Expander may show demo gallery content so you can see what the tool produces, but you need to sign in before expanding your own images.
Output aspect ratios
Choose the target shape from the Output Aspect Ratio menu:
| Option | Ratio | Good for | |---|---:|---| | 16:9 Landscape | 16:9 | Game splash art, banners, widescreen scenes, video thumbnails | | 9:16 Portrait | 9:16 | Mobile wallpapers, story-format images, vertical social posts | | 1:1 Square | 1:1 | Avatars, thumbnails, marketplace images, square previews | | 4:3 Standard | 4:3 | Classic game screens, presentation layouts, standard backgrounds | | 3:4 Portrait | 3:4 | Character cards, portrait art, vertical compositions | | 3:2 Photo | 3:2 | Photography-style landscape framing | | 2:3 Portrait | 2:3 | Poster-like vertical compositions | | 4:5 Portrait | 4:5 | Social feed portraits, product-style images, character crops | | 5:4 Landscape | 5:4 | Slightly wide art, framed presentation images | | 21:9 Ultrawide | 21:9 | Cinematic banners, panoramic environments, wide game scenes |
The preview frame updates when you change the aspect ratio. Your selected queued image appears centered inside that frame over a checker-style background so you can see how much new area will be generated.
Typical workflow
- Open Image Expander.
- Sign in if you are not already signed in.
- Choose an Output Aspect Ratio.
- Upload one or more images by clicking the upload area or dragging files into it.
- Review the Queue and select an image to preview it in the target frame.
- Optional: enter an Expansion Prompt describing what should continue into the expanded areas.
- Optional: adjust the Filename pattern for downloads.
- Use the inspector panel to confirm the number of queued images.
- Click Expand Image for one queued image or Expand All for a batch.
- The tool switches to Expanded Images while the results process.
- When an image completes, click it to open the lightbox, download it, delete it, or drag it into WizardGenie when available.
Importing images
Image Expander supports several ways to add images:
- Click the Upload Images drop zone and choose files from your device.
- Drag and drop image files into the upload area.
- On desktop, use the additional upload area in the inspector panel.
- When used with other Sorceress tools, images may be passed into Image Expander directly.
- When opened inside WizardGenie, files can be dropped in from the Explorer if supported by the current WizardGenie context.
Uploaded images are added to the queue. The queue shows each image thumbnail, filename, and dimensions.
If a file is not an image, it is ignored. If a file is too large in the main upload flow, Image Expander shows a Files Too Large message listing the skipped files.
Working with the queue
The queue is where you prepare images before generation.
From the queue you can:
- See how many images are waiting.
- View each image thumbnail, filename, and pixel dimensions.
- Click an image to select it for the central preview.
- Remove a single queued image with the X button.
- Use Clear to empty the queue.
The selected queued image appears in the preview frame. This does not change the batch settings; it only changes which queued image you are inspecting.
If you change the aspect ratio while images are queued, the preview updates to show the new target shape.
Previewing the expansion
The Expander tab shows the selected queued image inside the output frame. The label above the preview shows the selected aspect ratio and notes that the image expands outward from the center.
Use the preview to check:
- Whether the target shape is appropriate for the source image.
- How much new space will be added horizontally or vertically.
- Whether important objects are near the edge and may be difficult to extend.
- Whether a less extreme aspect ratio might produce a more natural result.
The preview is a framing guide, not the final generated result. The AI-generated areas are created after you start the expansion.
Expansion prompt guidance
The Expansion Prompt field is optional. It describes what should appear in the newly created areas outside the original image.
Good prompts are short, specific, and consistent with the source image:
- “Continue the snowy mountain landscape with cloudy sky.”
- “Extend the cyberpunk city street with neon signs and rain.”
- “Add more dark forest and mist around the character.”
- “Seamless studio background with soft shadows.”
- “More ocean horizon and warm sunset sky.”
For best results:
- Describe the added space rather than rewriting the whole image.
- Keep the prompt aligned with the existing scene, lighting, and style.
- Mention important environment features if the edges are ambiguous.
- Use simple language for background continuation.
- Try leaving the prompt blank first when the image already has a clear, repeatable background.
If a result adds unwanted objects, try again with a more direct prompt such as “empty studio background,” “continue only the sky and mountains,” or “no additional characters.”
Starting an expansion
The inspector panel shows the queued image count and the generate button. The button label changes depending on the current state:
- Sign In to Expand — you are not signed in.
- Add Images to Expand — the queue is empty.
- Max 3 Active — there are already 3 expansions running.
- Expand Image — one image is queued and ready.
- Expand All (number) — multiple images are queued and ready.
When you start a batch, Image Expander moves to the Expanded Images tab and begins adding new gallery items. Batch jobs may appear a short time apart rather than all at once.
Expanded Images gallery
The Expanded Images tab contains your recent Image Expander results. Signed-in users see their recent expansion history. The gallery loads up to the current recent-results limit used by the tool.
Gallery tiles can appear in these visible states:
- Expanding... — the image is still being generated.
- Completed — the result is ready to open, download, delete, or drag into WizardGenie when embedded.
- Failed — the expansion did not complete. The tile may show an error message and includes a Remove option.
On desktop, use the Grid slider to change the number of gallery columns from a denser to a larger preview layout.
The gallery header also shows the number of completed images currently available.
Lightbox viewer
Click a completed gallery image to open it in the full-screen lightbox.
In the lightbox you can:
- View the expanded image at a larger size.
- See the source image dimensions recorded for the expansion.
- See the prompt used for the result.
- Download the image.
- Delete the image.
- Move to the previous or next completed image with the on-screen arrows.
- Close the lightbox with the close button or by clicking outside the image.
Keyboard shortcuts are also supported while the lightbox is open:
- Left Arrow — previous completed image.
- Right Arrow — next completed image.
- Escape — close the lightbox.
Downloading results
Completed images can be downloaded individually from:
- The download button on a gallery tile.
- The Download button in the lightbox.
Downloads are saved as PNG files.
Downloading a batch
After you start a batch, a Download Batch button appears when completed images from that most recent batch are available. The button shows how many completed images are ready in that batch.
Batch download downloads each completed image individually. Some browsers may ask for permission when a website downloads multiple files.
Filename pattern
The Filename field controls the base name used for downloaded files. The default is:
{filename}
When the pattern includes {filename}, Image Expander replaces it with an automatic expanded-image name. If you enter your own text without {filename}, that text is used as the base filename. The .png extension is added automatically.
Examples:
{filename}creates an automatic name.hero-bannerdownloads ashero-banner.png.expanded-{filename}keeps the automatic identifier but adds your prefix.
Deleting results
You can delete a completed result from:
- The delete button on a gallery tile.
- The Delete button in the lightbox.
Failed items can be removed from their gallery tile. Deleting or removing an item clears it from your Image Expander gallery.
Mobile layout
On smaller screens, Image Expander uses slide-out panels so the preview and gallery have more room.
At the top of the mobile layout:
- Upload opens the left panel with aspect ratio, upload, queue, prompt, and filename controls.
- Inspector opens the right panel with upload access, queued count, and the generate button.
Tap the dark backdrop outside an open panel to close it.
WizardGenie integration
When Image Expander is opened inside WizardGenie, completed images can be dragged into the WizardGenie Explorer.
You can drag:
- A completed image tile from the gallery.
- The Drag to WizardGenie Explorer button in the lightbox.
Only completed images can be dragged. Images that are still expanding or failed cannot be dragged into WizardGenie.
Tips for better results
- Choose an aspect ratio close to the original if you want a subtle, natural extension.
- Use 16:9 or 21:9 for landscapes, environments, banners, and game splash art.
- Use portrait ratios for characters, posters, mobile layouts, and social posts.
- Use 1:1 Square for thumbnails, avatars, and marketplace-style images.
- If the image has a simple background, try the first generation with no prompt.
- If the image has a complex setting, describe the environment clearly in the prompt.
- Avoid asking for a completely different scene unless you want a more dramatic reinterpretation.
- Keep important text, logos, UI, and faces away from the image edges when possible.
- Test one image first, then batch similar images once the settings work well.
- For extreme changes such as portrait to ultrawide, expect more creative interpretation in the added areas.
Troubleshooting
“Sign In to Expand” appears
You are not signed in. Sign in before creating new expansions.
“Add Images to Expand” appears
The queue is empty. Upload at least one image first.
“Max 3 Active” appears
There are already 3 expansions running. Wait for one to finish or fail before starting more.
“Files Too Large” appears
One or more files exceeded the upload limit and were skipped. Use a smaller image file and try again.
A file does not appear in the queue
Make sure the file is an image. Non-image files are ignored. If the file is very large, reduce its size and upload again.
An image stays on “Expanding...”
Processing time can vary. Wait a few minutes, especially for batches. If the item eventually fails, remove it and try again with a smaller image, a less extreme aspect ratio, or a clearer prompt.
The expansion failed
Try one or more of the following:
- Retry the same image.
- Use a smaller or simpler source image.
- Choose an aspect ratio closer to the original.
- Add a prompt describing the background continuation.
- Avoid source images with important text or complex objects right at the border.
- Remove the failed tile if you no longer need it.
The result does not match the original scene
Revise the prompt to describe the continuation more specifically. Include setting, lighting, weather, materials, or background style. You can also choose a less extreme aspect ratio so the tool has less new space to invent.
Download does not start
Try opening the image in the lightbox and downloading from there. If you are using Download Batch, your browser may block multiple downloads; allow downloads for Sorceress or download images individually.
FAQ
Does Image Expander crop my original image?
The tool is designed to expand outward from the centered source image into the selected aspect ratio. The preview shows the source image inside the target frame before generation.
Can I expand multiple images at once?
Yes. Upload multiple images, confirm the queue, then click Expand All. The same selected aspect ratio and prompt are used for the batch.
Can each image in a batch use a different aspect ratio?
No. Run separate batches if you need different aspect ratios or prompts.
Can I leave the prompt blank?
Yes. Leaving the prompt blank lets the tool infer how to continue the image from the source.
How many previous results are shown?
The gallery loads recent Image Expander results, up to the current recent-results limit used by the tool.
Can I delete results?
Yes. Use the delete button on a gallery tile or in the lightbox. Failed items can be removed from the gallery tile.
