Resize Images

Change image dimensions by pixels or percentage.

About this tool

Change an image width and height in pixels inside your browser, preserving the aspect ratio by default.

How to use this tool

  1. Choose a JPG, PNG or WebP image.
  2. Enter width and height, or unlock the aspect ratio.
  3. Review the new dimensions and download the image.

Practical example

A 1200 × 800 image resized to width 600 becomes 400 pixels high when the aspect ratio is preserved.
