Extend images with AI outpainting
Add room to your composition in a new aspect ratio.
AI outpainting extends an existing image beyond its original edges by generating new content around the source while keeping the original pixels unchanged. In getimg.ai, Outpainting is one of two modes inside Resize image: drop in a source, pick a new aspect ratio, and the model paints the added canvas with content guided by the source image's lighting, palette, and composition.
Built for production, not one-off edits
Three details that matter once outpainting moves from a single image to ongoing production work.
Ready for client work
Commercial rights are included on paid plans. Use outpainted images in client work, ads, product visuals, and other commercial projects.
Run a batch at once
Resize image takes one source or a batch. Apply the same aspect ratio and Outpainting mode across several images and run them in a single pass — batch size depends on your plan.
Upscale after outpainting
The extended image lands in your gallery with the rest of your assets. Send it to the Upscale image Action for higher-resolution output, up to 16K depending on your plan.
Outpainting, Smart Resize, and upscaling
Three different jobs that are often confused. Here is what each one changes about your image.
Outpainting
Keeps the original pixels and generates new space around them. The canvas grows; the source stays exactly as shot.
Smart Resize
Regenerates the full image in a new format. Use it when a clean re-render of the same composition matters more than pixel-level fidelity.
Upscaling
Increases resolution and detail without changing the frame. The scene stays the same size; the pixel count goes up.
Outpaint in three clicks, or rebuild it manually
Outpainting removes much of the manual canvas expansion and cleanup from the workflow.
With getimg.ai
1. Drop the image into Resize image
Open the Resize image Action in the sidebar and drop your source into the box at the bottom.
2. Pick the new aspect ratio
Choose the target shape: 1:1, 9:16, 16:9, 21:9, or another supported ratio for the placement.
3. Switch the mode to Outpainting
Toggle from Smart Resize to Outpainting and getimg.ai paints the added area around your original.
Doing it manually
- Open the source in a raster editor and resize the canvas
- Fill the empty area with clone-stamp, healing brush, or content-aware fill
- Paint out repeats and seams, then add matching detail by hand
- Color-grade the new section, flatten, and export
- Repeat for every image and every format
Source format to target format
The jobs that come up most often when production teams switch to outpainting in Resize image.
Outpainting
Extend the canvas, keep the original.
Outpainting sits in the Resize image Action. Pick a new aspect ratio and getimg.ai paints what isn't there, working outward from your source. The original pixels stay untouched, and the added area continues the scene guided by the source colors, edges, and light direction.

Open the Resize image Action and start with any source image you already have.
Frequently Asked Questions
Outpainting keeps the original pixels of your image and generates the area around them to fill a new, larger aspect ratio. The model reads the source's color tones, light direction, and subject placement, then paints the surrounding pixels so the addition follows what is already in the image.
It is one of two modes in the Resize image Action. Outpainting preserves the source pixel-for-pixel; Smart Resize is the other mode, where the image is regenerated at the new aspect ratio. Pick Outpainting when every original pixel matters; pick Smart Resize when a clean re-render of the same composition is what you need.
AI outpainting and inpainting do opposite jobs. Outpainting extends an image past its current edges, generating new pixels around what is already there. Inpainting works inside the current edges, adding, removing, or replacing parts of the image you already have. Use outpainting when you want more image; use inpainting when you want to change what is in the image.
In getimg.ai, outpainting lives in the Resize image Action. Pick a new aspect ratio and the model paints the surrounding canvas. Inpainting lives in image editing: open any image, mark what you want to change, and describe the new content in the prompt.
AI image extension is a common use case for outpainting. Outpainting is the technique that generates new content beyond the original image boundaries; an AI image extender is a tool that applies it to the everyday job of uncropping a photo or changing its format. In getimg.ai both run through the same Outpainting mode in Resize image.
Outpainting increases the canvas and the scene: it generates content that was never in the frame. Upscaling increases resolution and detail within the frame you already have, without changing the composition. Outpaint first to reach the format you need, then upscale the result for delivery.
Outpainting reuses every pixel of your source, so source quality matters. High-resolution, well-lit images give the model the most signal to work with, and the added pixels follow the source more closely on detail, texture, and lighting. Low-resolution or heavily compressed sources can produce extensions that look softer than the original, especially on large jumps like 1:1 to 16:9.
Resize image supports nine ratios for outpainting: 1:1 for square posts, 9:16 for Stories and Reels, 16:9 for banners and video, 4:5 for social portrait, 21:9 for wide hero and cinematic layouts, plus 4:3, 3:4, 3:2, and 2:3. Pick the target ratio before running outpainting and the model paints the canvas to fit that shape.
Your original stays where you uploaded it. Outpainting saves the extended version as a new file in the gallery, so the source is always available to re-run at a different aspect ratio, send to another Action, or compare against the result.
Yes. Resize image accepts a single image or a batch. Pick from the gallery or upload fresh sources, then run outpainting on all of them with one aspect ratio choice. Batch size depends on your plan.
Yes. Commercial rights are included on paid plans (Entry, Core, Plus, Ultra). Use outpainted images in client work, advertising, product visuals, and other commercial projects.
