Missing background? Let AI fill it in like magic

Captured the perfect shot but lost part of the background? Or does your subject look cramped in a square format? Let generative fill take care of it.
Our AI learns the style and details of your image—colors, lighting, and textures—and seamlessly expands it. Whether it’s ocean waves and skies, café tables and chairs, or buildings and trees, the fill blends in naturally as if it were always there.
You can convert your image to any ratio—from 1:1 to 16:9—without needing separate versions for each platform. It’s not just expanding—it’s recreating with context.

One image, endless uses with smart editing tools

Once filled, your image becomes a powerful starting point. Add text to turn it into a poster, place stickers or shapes to highlight key parts, or apply filters to create a different mood.
The extra space makes it easier to place logos, insert copy, or apply stylish frames. Your original stays untouched while new elements blend in smoothly.
With just a few edits, a simple photo becomes an infographic, a product shot becomes a banner, and your idea becomes a polished design.
