Canvas Expander

Artwork extended beyond its original frame into a wide banner
Artwork extended beyond its original frame into a wide banner

Continues a scene past its original edges. Useful when a portrait needs to become a banner, when a cover needs bleed, or when a composition would simply be better with more room on one side.

Expand one direction at a time

Each expansion is an act of invention. Inventing on all four sides at once compounds the guesswork and the errors multiply.

  • Extend one edge, check it, then extend the next.
  • Modest expansions look best. Past about half the original dimension the invented area dominates, and upscaling will only magnify it.
  • Expand away from your subject, not toward it.

What the model uses as evidence

Only what is already at the existing edge.

Continues well

A wall, a floor, sky, or water running to the border. There is an obvious continuation.

Continues badly

A figure cropped mid-body. The model has to invent anatomy with no reference.

Continues unpredictably

Complex scenes with several competing elements at the edge.

Where it fits in the order

Expand before you upscale. Doing it the other way costs more and gives the model a harder job. If you only need different framing rather than more image, the cropper is free and instant.

Extending a frame

Worked example: turning a portrait into a wide banner

Cost5 credits
MethodOne edge at a time

The exact instruction

extend the scene 400px to the right only, continue the brick wall and the wet pavement, match the existing light direction and colour temperature

What comes back

Extending one edge at a time keeps the invention bounded. The model continues what is already at that border, so a wall running to the edge continues convincingly.

Common questions

How far can I expand?

Modest expansions look best. Beyond about half the original dimension the invented area dominates and loses coherence.

Can I expand an upscaled image?

You can, but expand first and upscale last. The reverse costs more and works worse.

Why did it invent a limb?

You expanded toward a cropped figure. Expand away from your subject instead.

Where to go next

This tool is usually used alongside reframe instead, compose a cover and upscale afterwards.
