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 background results. JPG, PNG, WebP up to 7MB.

    Expect: Simple backgrounds like sky or walls: 20-30 seconds. Complex patterns or scenes: may need 2-3 refinements.

  2. Describe how to extend

    Type exactly what you need: 'extend the background upward to add more headroom' or 'add more background space on both sides for banner crop.' Be specific about which direction and how much. The AI understands and generates matching content.

    Tip: Mention key elements to match: 'extend with matching blue sky and soft clouds' helps the AI continue the existing scene naturally.

    Copy one of these to get started:

    Portrait to landscape for social media banner extend the background on both left and right sides to create landscape aspect ratio, matching the existing background texture and colors

    Environmental portrait with more scene extend the background on the right side to show more of the environment and setting, generating matching scenery

  3. Generate and review

    Tap generate and examine where the new content meets the original. Check for texture continuity, lighting consistency, and natural transitions. These seam areas need the most attention.

    Tip: Zoom to 100% at the edges where new content was added. That's where mismatches become visible when used in final designs.

Quick answers

Do I need to mark where to extend before describing?

No! Just describe what you want: 'extend background on the left' or 'add more sky above.' The AI understands directional instructions.

Can I extend in multiple directions at once?

Yes. Type 'extend the background on both left and right sides' or 'add more space on all four sides.' The AI can generate matching content in multiple directions simultaneously. This is perfect for aspect ratio conversions where you need to add space symmetrically.

How much can I extend a photo?

For best results, extend up to 50% of the original dimension in any direction. Larger extensions require more AI generation and may show inconsistencies. If you need dramatic expansion, consider doing it in stages: extend once, then extend the result again.

What backgrounds extend best?

Simple, consistent textures extend most seamlessly: clear sky, solid colored walls, out-of-focus bokeh, water, and grass. Complex patterns like detailed architecture or crowds are harder because the AI must generate believable continuation. For complex scenes, be extra specific in your prompt about what elements should continue.

Can I use this to change the aspect ratio of my photo?

Absolutely. This is one of the most popular uses. Type 'extend background on left and right to convert to 16:9 widescreen' or 'add space above and below for 4:5 portrait.' The AI adds matching content to reach your target ratio without cropping or stretching your subject.
