Content doesn't fit the screen? Fix it with AI outpainting

Screens have a fixed shape — usually 16:9 (landscape) or 9:16 (portrait). When an image doesn't match, your options are normally to stretch it (distorted) or crop it (lose parts). impressBox offers a third, better option: outpainting.

What outpainting does

Outpainting uses AI to extend the image outward into the missing space, generating matching surroundings so the picture fills the screen naturally — no stretching, no cropping.

How it works

Outpainting is offered when you add an image through the impressBox AI assistant — not through the plain upload dialog. The assistant checks the image's shape and, if it doesn't match, offers to reshape it:

1. You add an image whose shape doesn't match a supported screen ratio (16:9 or 9:16).

2. impressBox detects the mismatch and offers to outpaint. Outpainting is on by default.

3. You choose:

   • Proceed — impressBox generates an outpainted version and shows you a preview.

   • Skip — the image is added as-is, without outpainting.

4. If you previewed, you can save the outpainted image, try again for a different result, or decline and keep the original.

How do you know if you need it? You don't have to check in advance. impressBox only offers outpainting when it detects a mismatch with a supported screen shape (16:9 or 9:16). If your image already fits, it is added as-is and you are never prompted — so if no outpainting offer appears, there is nothing to fix.

Choosing an orientation

You can ask for a specific shape — for example, portrait (9:16), landscape (16:9), 4:3, 1:1, or an exact size like 1920x1080. impressBox outpaints to that target.

When to skip

Skip outpainting when the image is already the right shape, or when you specifically want the original framing (e.g., a logo that shouldn't have invented surroundings).

Supported outpainting aspect ratios

When you outpaint, impressBox can target any of the following shapes. Request them as a ratio (e.g. 4:3), an orientation (portrait/landscape), or an exact pixel size (e.g. 1920x1080):
