AI image extender: give your image space to breathe

Changing a portrait image into a wide rectangle by stretching changes the shapes inside it. Cropping removes content, while a plain border adds space without continuing the scene. Outpainting takes a different approach: it estimates a surrounding environment from the visible edges.

• Subject preservation: the aim is to keep the original person or product recognizable, without requesting a face swap. Compare the source area after processing.
• Scene continuity: inspect light direction, color temperature, surface texture and shadows at the join.
• Useful canvas ratios: choose a frame for the destination, rather than forcing the subject to fit by stretching it.
• Optional edge hints: a brief material or setting description can guide an ambiguous border; avoid asking for a completely different scene.

Use the controls already in the workbench to describe the surrounding canvas. A source photo is required.

• Presets and custom dimensions: choose a common ratio or enter pixel width and height. Custom fields accept values from 64 to 8192; supported generation dimensions also depend on the selected service.
• Edge hint: describe a background such as pale studio wall or open sky, or leave the field empty when the visible scene supplies enough context.
• Source comparison: review the original area as well as the new margins. Do not assume an untested pixel-for-pixel lock.
• Connected workflow: improve a soft source first, then extend the composition and enlarge the chosen result if the destination needs more pixels.

Aspect ratio describes shape, not sharpness. Check the platform’s current layout requirements and reserve space around important content.

• 1:1 square: a balanced starting point for avatars, square product images and feed tiles. Keep important details clear of any circular avatar crop.
• 4:5 portrait: useful for a taller feed composition when the subject needs room above and below.
• 16:9 landscape: a common shape for desktop backgrounds, presentation slides and video cover artwork.
• 9:16 vertical: suits phone backgrounds and vertical story or video-cover layouts; leave space for interface overlays.
• Custom canvas: enter width and height for a particular design. Check the result’s actual dimensions before placing it into a print or advertising template.

A clear source and a modest framing change give you a more useful result to evaluate.

• Use the highest-quality original instead of a repeatedly compressed screenshot. Edge texture provides context for the surrounding scene.
• For a large change in shape, consider smaller extensions and inspect each result. Each new run uses credits and can introduce new mistakes.
• Keep edge hints short and relevant. A simple sky or studio backdrop may need no text; complex architecture often needs more review rather than a longer prompt.
• Check horizons, shadow direction and perspective. A clipped hand or chair at the edge can lead to an implausible continuation.

Separate cleanup, composition and resolution decisions so you can review each change.

• Before extending, remove distracting text or brush-marked clutter that touches an edge, then check the repaired area.
• If a portrait is soft, enhance the source and compare the person’s features before continuing.
• After choosing a satisfactory extended composition, use Image Upscaler when you need a larger digital file.

Enhance the source

Upscale the finished composition

• Extension adds surrounding content; it is not a substitute for increasing detail within the same crop. Use an upscaler for that separate task.
• This tool starts from an existing image, rather than making a picture from an empty text-only canvas.
• The goal is to retain the source composition, not move or redesign the subject. Check for unexpected changes instead of assuming a perfect lock.
• Generated borders cannot reveal the true people, logos or objects that were outside the photograph. New scene details are predictions.

A different frame can make an existing image usable in more layouts, provided the generated area is appropriate for the purpose.

• Creators and social media managers: adapt a still for a feed tile, vertical cover or wide video thumbnail while protecting room around the subject.
• Designers and web developers: prepare an image for a slide or website banner with space for a headline added in a layout tool.
• Merchants: add studio-style margins for product copy, then verify that the actual product and label remain accurate.
• Photographers and wallpaper users: create a different display shape without simply stretching a travel photograph.
