World's simplest online Portable Network Graphics (PNG) aspect ratio changer. Just import your PNG image into the editor on the left, select a preset or custom aspect ratio (or enter exact width and height), and you will instantly get a PNG resized and cropped to match the chosen proportions on the right. In the tool options, you can choose whether to scale and crop the PNG to fit the new size or to only crop the PNG to maintain its original pixel size. Free, quick, and very powerful.

This browser-based utility changes the aspect ratio of PNG images. The aspect ratio is the proportional relationship between the width and height of an image. It's critically important for displaying PNGs on various screens and platforms. For example, video platforms typically require a 16:9 aspect ratio, while a profile picture is usually a square with a 1:1 ratio. This tool allows you to set a new aspect ratio for your PNG file and, if necessary, scale it up or down to precisely match the desired dimensions. In the first group of options, you can choose how to define the proportions for your PNG. You can select a preset ratio from the "Common Aspect Ratio" list, which includes popular proportions such as 16:9, 1:1, 4:5, etc., along with specific pixel dimensions commonly used for social media and content platforms. If the presets don't fit your needs, activate "Set Custom Aspect Ratio" and enter two numbers: "Width Part" and "Height Part". This defines the ratio as "width:height" (for example, 4 and 5 produce a 4:5 ratio). This option is useful when you need a non-standard but proportionally accurate frame. Another option is "Set Exact Dimensions", where you can specify exact "Width" and "Height" values in pixels. Next, you can decide how the image should be adjusted. In "Scale and Crop PNG" mode, the tool automatically resizes and crops the PNG so that the final image perfectly matches the selected ratio and pixel dimensions. The "Crop PNG Only" mode simply trims the image to reach the new proportions without changing the original pixel size. When cropping parts of the PNG, the cropping area appears in the input preview. You can adjust its position directly in the preview or via the options panel by setting the horizontal and vertical offset of the crop area. When scaling the PNG, you can enable or disable pixel smoothing to control how pixel details appear after resizing. The tool also displays technical information about the dimensions of the input and output images, their aspect ratios, and the cropping region. Png-abulous!

In this example, we convert a vertical PNG into a wide horizontal image by selecting a preset 16:9 aspect ratio (1280×720). The tool scales the picture up and crops the top and bottom areas to match the new ratio. We enable the pixel smoothing to soften pixels after resizing. As a result, the composition centers around the red huts lined along the horizon. (Source: Pexels.)
In this example, we change the aspect ratio of a PNG from its original 3:2 to a 5:4 proportion without scaling the pixels. We enable the "Set Custom Aspect Ratio" mode and set the width part to 5 and the height part to 4. Crucially, we apply the "Crop PNG Only" mode, meaning the original image size is maintained while we trim a strip from both the left and right sides. We manually adjust the horizontal offset in the preview to focus on the bread. (Source: Pexels.)
In this example, we start with a square PNG that has a transparent background. We switch to the exact size mode and set the width to 120 px and the height to 100 px, which corresponds to a 6:5 ratio. Since the "Scale and Crop PNG" option is enabled, the image is resized and cropped to fit the new dimensions, resulting in a significantly smaller PNG that still preserves its transparency.
