RNDRS · Image extender

Your render, beyond the frame

The render is perfect; the crop is wrong for the layout. The RNDRS image extender outpaints beyond the original frame — continuing architecture, landscape and sky coherently — so a tight concept render becomes a full-bleed hero, a banner or an A0 board image.

How it works

01 · Upload

Render or photo that needs more canvas

02 · Extend

Choose the direction and amount of new frame

03 · Generate

Architecture and context continue seamlessly

04 · Upscale

Push the final wide frame to 4K for print

Coherent continuation

Facade rhythms continue at the right module, landscape flows naturally, the sky stays one sky. Extensions read as if the camera always saw that much.

One render, every format

Square for the feed, 16:9 for the deck, ultra-wide for the website hero, portrait for the board — all extended from one source image instead of four re-renders.

Save the almost-perfect shot

Great angle, clipped tower top? Extend upward instead of re-rendering. Tight site photo missing context? Widen it and the street appears.

Frequently asked questions

What does the image extender actually do?

It generates new image content beyond the original borders (outpainting), matched to the existing architecture, materials, lighting and perspective.

Can I extend in just one direction?

Yes — extend any single edge or several at once, to the aspect ratio your layout needs.

Will extensions match my building's facade?

The extender continues visible patterns — structural rhythm, material coursing, fenestration — so the added frame is consistent with what exists.

What does an extension cost?

One credit per extension. Combine with the 4K upscaler when the final wide image is headed to print.
