How to Change Aspect Ratio Without Cropping

  1. 1

    Upload your image

    Start by uploading the JPG or PNG file you want to resize. This could be a wide landscape photo or a vertical portrait.

  2. 2

    Enter your prompt

    Describe how you want to expand the image. For example, 'change this to a square image' or 'make this photo vertical by adding more sky.'

  3. 3

    Generate a new aspect ratio

    Our AI will analyze your photo and prompt to intelligently expand the scene, creating a new version of your image in the desired dimensions.

  4. 4

    Download your expanded image

    Your new, perfectly resized high-resolution image is ready to be downloaded in PNG format, completely watermark-free.

Instead of stretching or cutting your image, our tool uses AI to imagine and generate what’s outside the frame. This is perfect for when you have a beautiful panoramic landscape and need to fit it into a vertical format for a social media story. The AI intelligently adds more sky, more water, or more of the scene, creating a natural-looking extension of your original photo. Keep every detail you captured, like the ducks on the water or the framing trees, while fitting your image into any required dimension.

Expand Your Photos, Not Just Resize Them

Stop sacrificing parts of your best photos for social media. Our AI image extender makes it simple to adapt any picture for different platforms. Turn a wide, panoramic photo into a square post for your Instagram feed or a vertical image for a Reel or Story without awkward cropping. You no longer have to choose between showing the whole landscape and fitting the platform's requirements. Our tool helps you repurpose your content effortlessly, ensuring your images look great on every social media channel, every single time.

Perfectly Frame Every Shot for Social Media

Changing an image's dimensions often leads to a loss of quality or distorted pixels. Our tool avoids this by generating new, high-resolution content to expand your image. When you change from a horizontal to a vertical format, the AI doesn't just stretch the existing pixels; it creates brand new parts of the scene that match the style, lighting, and texture of your original photo. This means your expanded images remain sharp and clear for any professional or personal project without visible quality degradation.

Preserve Image Quality and Detail
