Smart Resize: the AI image expander for any aspect ratio

Your photo is portrait and the slot is landscape. Smart Resize picks a new aspect ratio and generates the missing edges to match the scene, so nothing gets cropped and nothing gets stretched. Upload any image, choose the shape you need, download.

What is an AI image expander?

An AI image expander extends a photo beyond its original borders by generating new pixels that continue the scene, instead of cropping or stretching it. Smart Resize does this for a new aspect ratio: upload a photo, pick a ratio from the list, and the preset fills the extra canvas with background that matches the original light and perspective.

What Smart Resize does

Expand, uncrop and reshape images without losing the part that matters.

  • Change aspect ratio without cropping

    Take a 1:1 product shot to 9:16 for a story or 16:9 for a banner. The subject stays exactly where it was, and the new space is filled with matching scene, not blur or letterboxing.

  • Uncrop and outpaint in one step

    Tight framing, a cut-off edge or a photo shot too close: Smart Resize rebuilds what sits outside the frame so the image feels like it was always that size.

  • Edges that match the original

    Walls, floors, sky, bokeh and fabric continue naturally into the expanded area, so the result holds up at full size on a product page or a billboard mockup.

  • Part of 70+ AI tools

    Your Artlist credits work across the whole toolkit. Reframe a video instead with the Aspect Ratio Changer, clean up a shot with the background changer, or generate new images with Artlist's AI image generator.

Who uses Smart Resize?

Anyone who has to publish one image in five different shapes. It is the fastest way to expand an image for every placement without going back to the source files.

  • Social media managers

    Turn a square post into a story, a reel cover and a pinned banner from the same photo. Every placement gets the full scene instead of a crop.

  • E-commerce and marketplace sellers

    Fit product shots to marketplace ratios and ad specs without reshooting. Expand the background and keep the product untouched.

  • Designers and marketers

    Fill a layout that needs a wider or taller image than the one you were handed. Expand first, then drop it straight into the design.

Frequently asked questions

Resizing changes the dimensions of the pixels you already have, which crops or stretches the picture. Expanding adds new image around the original. Smart Resize expands: it generates matching background so the photo fits a new aspect ratio with the subject intact.

Smart Resize offers a list of common ratios for social, web and print placements, so you pick the shape you need rather than entering pixel values. Upload once and run it again for each ratio you want.

The generated edges follow the lighting, perspective and textures of the original, so backgrounds like walls, sky, sand or studio sweeps extend naturally. Simple, consistent backgrounds give the cleanest results; busy scenes with many objects may need a second run.

Yes. The subject stays as it is and only the canvas grows around it. Keep the subject away from the very edge of the original frame so the preset has context to continue the scene.
