THE RIGHT SHAPE. NO STRETCHING.

IMAGE ASPECT RATIO

Find an image's aspect ratio, then crop it or add padding to fit a new shape. All processing stays in your browser.

PNG, JPG or WebP · up to 20 MB / 16 megapixels. Animated files use one frame.

No image selected.

CHANGE ASPECT RATIO

Position moves the crop or places the image inside the padded canvas. Crop removes edges; padding keeps the full image. Neither mode stretches the image.

ORIGINAL / CROP GUIDE

OUTPUT PREVIEW

Choose an image to begin.

Checkerboard indicates transparency and is not exported. Output keeps original pixel scale; dimensions are rounded to whole pixels, so the ratio can differ slightly. Output limit: 16 MP and 16,384 px per side.

ASPECT RATIO FINDER

Upload an image to see its width, height and simplified ratio. For example, 1920 × 1080 reduces to 16:9. Dimensions such as 601 × 401 retain their exact ratio rather than being labeled 3:2.

ASPECT RATIO CHANGER

Select a preset or enter a custom width-to-height ratio. Use Crop edges for a full-frame result, or Add padding to keep the entire picture. Adjust the position sliders and review the output before downloading.

Does padding remove my original background?

No. Transparent padding adds empty space around your picture. An existing solid background stays solid. Choose Solid color to place both the image and new padding over your chosen color.

Does this resize to a specific pixel resolution?

This tool changes the shape at the original pixel scale, rather than setting an arbitrary output resolution. Cropping produces a smaller canvas; padding produces a larger canvas.

Are files uploaded or stored?

No. Images are decoded and processed locally. Reloading clears the image. PNG export does not copy original metadata.
