Add space around a photo instead of cutting it

Sometimes the problem is not that there is too much in the frame, but too little. A square photo will not fill a wide hero banner. A portrait leaves no room for a headline. A subject sits awkwardly against the edge. Expanding - Also called uncropping or outpainting - Grows the canvas and fills the new area so the image fits its new home.

Control where it grows

  • All sides - Add an even margin around the whole image.
  • Wider or taller - Change the aspect ratio toward landscape or portrait.
  • A single edge - Push out the left, right, top or bottom only, for headroom or copy space.

What it does well - And where to be realistic

img.now extends the canvas by mirroring and blending the existing edges, which looks seamless on open backgrounds: skies, water, walls, gradients and texture. Busy or highly detailed edges are harder to invent convincingly, so expand a little at a time for the cleanest result. Pair it with the cropper and resizer to get an image to the exact shape and size you need. Expanding the canvas is one form of generative fill; to erase an object and fill the gap instead, use the object remover. Every expanded image is saved in your img.now workspace.

Questions about the image expander (uncrop)

What does expanding or uncropping do?
It grows the image canvas beyond the original edges and fills the new space, so a photo that was framed too tightly gains room around the subject. It is the opposite of cropping.
When would I use this?
When a photo is the wrong shape for where it is going - For example turning a square photo into a wide banner, giving a portrait headroom for text, or adding margins so a subject is not jammed against the edge.
How does img.now fill the new area?
It extends the picture by mirroring and blending the existing edge pixels, then softens the seam so the added border matches the original. It works best for backgrounds like skies, walls, water and texture.
Will it change my original image?
No. The expanded version is saved as a new file in your workspace, so your original stays exactly as it was.
