About

About the Image Resizer

The Image Resizer changes an image's dimensions to an exact width and height, with optional aspect ratio locking so your photo or graphic scales proportionally instead of stretching or squashing. Reach for it when you need an image to fit a specific size — a thumbnail, avatar, web hero, or social post — or simply to shrink an oversized image down to manageable dimensions. Everything runs entirely in your browser, so your images never leave your device.

How to use the Image Resizer

  1. 1Open the Image Resizer and select or drop in the image you want to resize.
  2. 2Enter your target width and/or height in pixels.
  3. 3Keep the aspect ratio lock on to scale proportionally, or turn it off to set width and height independently.
  4. 4Preview the result to confirm the new dimensions look right.
  5. 5Download the resized image to your device.

Frequently asked questions

What does an image resizer do?

It changes an image's pixel dimensions — making it larger or smaller — to fit a target width and height. With aspect ratio control, it scales the image proportionally so it doesn't look stretched or distorted.

Is my data private and safe?

Yes. The tool runs 100% client-side in your browser. Your image is processed locally on your device and is never uploaded, stored, or tracked — nothing is sent to a server.

Is it free to use?

Yes, the Image Resizer is completely free to use, with no sign-up required.

What's the difference between resizing and cropping?

Resizing scales the whole image to new dimensions, keeping all the content visible. Cropping removes part of the image to change its framing. This tool resizes — it rescales the entire image rather than cutting anything out.

How do I resize an image without distorting it?

Keep the aspect ratio lock enabled and change just one dimension — the other updates automatically to keep the image's original proportions, so it never looks stretched or squashed.
