What does Image Resize do?

It changes the width and height of an image — either to an exact pixel size you type in, or by a percentage — without installing anything. Useful for fitting an image into a form, a social post, or a specific layout.

Common uses

  • Setting a photo to a required size for an upload form
  • Scaling down large images so they load faster
  • Preparing images for print or web at the exact dimensions you need

Key features

  • Custom dimensions — enter an exact width and height
  • Percentage scale — reduce or enlarge by 50%, 200%, and so on
  • Maintain aspect ratio — keep the original proportions to avoid distortion

How it works

You upload an image, choose either exact dimensions or a percentage, keep the aspect ratio on or off, and download the resized result. Processing is local, so your image is never uploaded.

Choosing a method

  • Use custom dimensions when a form or platform needs a specific size
  • Use percentage scale when you just want it smaller, e.g. 50%
  • Keep aspect ratio on to prevent stretching or squashing

Verdict

Image Resize handles exact sizing and quick scaling with flexible proportions. Open Resize, set your size, and download — free and private.
