Prompt-guided outpainting · Gemini 3 Pro Image
Every image ends too soon.
Outframe reads the pixels at your image’s edges — texture, perspective, light — and synthesizes the scene that should have been there. Sources up to 5 MB, renders in 10–30 seconds, every job versioned to your private workspace.

Protocol
Three steps, fully recorded.
Upload the source frame
PNG, JPEG, or WebP up to 5 MB. We read the exact pixel dimensions on the client before a single byte leaves your machine, then store the original in your private workspace bucket.
Describe the missing space
A short, concrete prompt outperforms an elaborate one. Name the materials, the light, and the direction of extension — the model reads context from the existing edge pixels.
Render and compare
Generation runs through Gemini 3 Pro Image with a typical ceiling of 30 seconds. Every job, prompt, and result is versioned to your workspace for side-by-side review.
“The frame is a decision someone made at capture time. Outpainting lets you revise that decision — with evidence from the pixels you already have.”
