📐 Image Resizer

Resize any image to exact pixel dimensions or a percentage, with an aspect-ratio lock. Free and fully in-browser.

About this Image Resizer

The Image Resizer changes the pixel dimensions of any photo or graphic right in your browser. Type exact width and height values, keep proportions with the aspect-ratio lock, or use the one-click percentage presets. It is handy for profile pictures, thumbnails, banners and upload forms that demand an exact size.

How to use it

  1. Choose an image from your device.
  2. Enter the new width and height, or tap a percentage preset.
  3. Keep the aspect-ratio lock on to avoid stretching.
  4. Press Resize Image and download the result.

Example

A 4000x3000 camera photo can be resized to 1200x900 for a blog post in a couple of seconds.

Frequently asked questions

Will resizing make my image blurry?

Shrinking keeps quality well. Enlarging far beyond the original size can look soft because no new detail exists.

What does the aspect-ratio lock do?

It keeps width and height proportional, so the picture never looks stretched or squashed.

Which format is the output?

The resized image downloads as a PNG. Use the Image Format Converter if you need JPG or WebP instead.
