How it works

  1. Upload your photo

    Upload a clear photo showing the area you want to edit. Good lighting and sharp focus help the AI deliver better image results. JPG, PNG, WebP up to 7MB.

    Expect: Simple extensions with uniform backgrounds: 20-30 seconds. Complex scenes with detailed edges: may need 2-3 refinements.
  2. Describe the extension you want

    Type your instruction: 'extend this image to the right' or 'expand the image upward by about 30%.' Be clear about direction and amount. The AI reads your edges and generates content that matches seamlessly. No marking needed—just describe where you want more image.

    Tip: Specify what should appear in the extension if it matters: 'extend right to show more of the beach and ocean horizon.'

    Copy one of these to get started:

    Portrait needs landscape aspect ratio extend this image to the left and right equally to create a 16:9 landscape crop, keeping the background natural and consistent
    Photo cropped too tight at top expand the image upward to add more sky and headroom, matching the existing clouds and lighting
    Instagram square to vertical story extend this image upward and downward to convert from square to 9:16 vertical format, continuing the scene naturally
    Product shot needs more table surface extend the image downward to show more of the table surface and add breathing room below the product
    3 more prompts
    Landscape needs vertical print format expand this landscape image upward significantly to fit a vertical print format, extending the sky with matching clouds and atmosphere
    Beach photo needs more ocean extend to the right to reveal more of the ocean and coastline, continuing the waves and water naturally
    Group photo cut off someone at edge extend the left side to recover the person who was cropped, matching the existing lighting and background
  3. Generate and review

    Tap generate and examine where the original meets the extension. Check that textures continue naturally, lighting stays consistent, and no obvious seams appear. Zoom to 100% to verify the blend.

    Tip: Look at the transition zone carefully. The AI usually nails large areas but sometimes struggles with fine repeating patterns like brick or fabric.
  4. Refine or extend further if needed

    If the extension doesn't match well, try being more specific about what should appear. You can also extend multiple times in different directions to build out your canvas progressively.

    Tip: For large extensions, go in stages. Extend 20% at a time rather than trying to double the image in one go.

Portrait to landscape for social cover

Vertical headshot needed to become a LinkedIn banner. Extended both sides to create proper 16:9 ratio while keeping subject centered.

Adding sky for dramatic composition

Mountain landscape was cropped too low. Extended upward to add dramatic sky and improve the composition balance.

Quick answers

How specific should my prompt be to get a good AI Image Extender result on the first try?

One sentence is usually enough: 'extend the image.' If the first result is off, refine with details — color, position, lighting, or what to keep. Each pass takes 20-45 seconds and runs separately, so you can compare. Free first edit per week, no signup.

How much can I extend an image in one go?

You can typically double an image's size in one direction, but results are better with moderate extensions (20-50%). For major expansions, extend in stages: add 30% to the right, review, then add more. This gives the AI better context at each step and produces more natural results.

Can I extend in multiple directions at once?

Yes, absolutely. Type 'extend left and right equally' or 'expand in all four directions to add a border.' The AI handles multi-directional extensions well, especially for symmetric expansions. For complex scenes, you might get better results extending one direction at a time.

Will the extended area match my image quality?

The AI generates content at your original image's resolution. High-resolution source images produce high-resolution extensions. If your original is 4000px wide and you extend right, the new pixels match that quality. Low-resolution sources will produce matching low-resolution extensions.

What if I need a specific final aspect ratio like 16:9?

Mention the target ratio directly: 'extend to create a 16:9 landscape aspect ratio' or 'expand to fit 9:16 vertical format.' The AI understands common aspect ratios and calculates how much extension each direction needs. You can also say 'extend right by about 30%' for proportional control.
