Extend any image with AI.

Continue a background past the edge of the frame, give a subject room to breathe, or reframe one shot for a placement it was never cropped for. For campaigns, catalogues, and the editing tools inside your own product.

One source, two placements

One square photograph, extended into a wide frame and a tall one. The square itself never moves or changes size — everything that appears around it is what the model added, and it came back within 0.7% of the same size in both.

GPT Image 2 · 1:1 → 16:9

Switch back to Source and anything that shifted inside the square becomes visible: reference editing re-renders the original rather than copying its pixels. Check faces, text and product detail before anything ships.

Past the edge of the frame.

“Continue the clifftop outward to reveal the coastline”GPT IMAGE 2 · 1:1 → 16:9

The scene keeps going.

An extension isn't a stretch. The model reads the light, the perspective and the texture it can already see, then keeps drawing in the same direction — so what arrives outside the original crop belongs to the same photograph rather than sitting beside it.

“Keep the bottle, continue the counter and the window light”GPT IMAGE 2 · 1:1 → 16:9

Room around the subject.

A product shot cropped tight for one placement suffocates in another. Extending outward buys the negative space a layout wants — the same bottle, the same label, the same light, with somewhere for the rest of the design to live.

“More sky above, calm space at the upper left”GPT IMAGE 2 · 1:1 → 16:9

Space for the words.

Every headline needs somewhere quiet to sit, and the shot you have rarely leaves any. Ask for more sky above the subject and you get a frame the copy can occupy — without shrinking the people in it or letting type crowd their faces.

Every model that can read your image.

Built for visual inference.

Serving images and video is a different problem from serving text — a single request can saturate a GPU, and none of the tricks that made language models cheap apply. Hedra's engine was built for exactly that workload.

Whichever model you choose — ours or anyone else's — it runs on the same infrastructure, behind one key, priced per generation.

Send an image and an editing instruction to any reference-capable model through one key, and bring the result straight back into your own workflow.

FAQs

An AI image extender generates new visual content beyond an existing image’s frame. Often called outpainting, it adds background and breathing room for a different composition instead of stretching the original pixels.

Send the image together with an instruction describing what should continue outside the frame — the target composition, and the details to preserve. That is one request to a reference-capable model through the API, or the same image and instruction dropped into Studio.

Not guaranteed. Reference-based editing can change details inside the original scene, so ask for the subject, lighting and composition to be preserved, and review faces, text and product detail before using the output. This workflow is not pixel-exact preservation.

Yes. Ask for a taller composition and describe the background to add above and below the scene. An aspect-ratio setting alone will not extend anything — the request has to carry the original image and an explicit editing instruction.

The reference-capable ones: Nano Banana Pro, Flux Kontext, the Flux.2 tiers, GPT Image 2.5, Seedream 5.0 and Grok Imagine all accept a source image with an instruction. Each model page lists the inputs it takes and its per-generation rate.

Per generation, and the rate depends on the model and the output resolution rather than on a seat. Each model page carries its own price.

Yes — that is the same request Studio makes. Post the source image and the editing prompt to a reference-capable model and read the result back; the model documentation lists supported inputs and output settings.
