How to Resize an Image to Exact Dimensions Online

What does image resizing mean?

Image resizing changes the pixel dimensions of an image. For example, you can change a photo from 3000 × 2000 pixels to 1500 × 1000 pixels while keeping the same proportions.

How to resize an image to exact dimensions

1. Choose your image

Open the Image Resizer and select the JPG, PNG, or WebP image you want to resize.

2. Enter the dimensions you need

Enter the required width or height in pixels. If you need an exact width and height for a particular use, make sure those dimensions match the requirements of the destination.

3. Keep the aspect ratio when appropriate

Keeping the original aspect ratio prevents the image from being stretched or squashed. If you enter both dimensions independently, the resulting image may look distorted when the new proportions do not match the original.

4. Download the resized image

Once the dimensions look right, download the resized file and use it wherever you need the new dimensions.

How to avoid stretching an image

The safest approach is to preserve the original aspect ratio. Changing width and height independently can change the proportions of the subject and make people or objects appear unusually wide or narrow.

Does resizing reduce image quality?

Reducing an image's dimensions can reduce the amount of detail available, while enlarging an image cannot recreate detail that was not present in the original. For that reason, enlarging a small image may make it appear softer.
