Image Resizer

Resize images to any dimension right in your browser.

ToolsSoup's Image Resizer is a free online tool that resizes photos and pictures to any width and height right in your browser. Drop in a JPG, PNG, or WebP, set your dimensions, and download the result in seconds — with no uploads, no watermarks, and no sign-up. Your images never leave your device.

What is an image resizer?

An image resizer changes the pixel dimensions of an image — its width and height — to make it smaller or larger. People resize images to meet upload limits, fit a website layout, prepare profile pictures and thumbnails, or shrink large photos so they load faster and take up less space. This tool redraws your image at the exact size you choose and exports a fresh file you can download.

How to resize an image online

Resizing an image with ToolsSoup takes just a few seconds:

  1. Click Choose an image and select the photo you want to resize.
  2. Enter a new width or height. Keep Lock aspect ratio on to scale proportionally without distortion.
  3. Pick an output format (PNG, JPEG, or WebP) and click Resize image.
  4. Download your resized image with one click.

How to keep the aspect ratio

The aspect ratio is the relationship between an image's width and height. Leave the Lock aspect ratio box checked and the tool automatically adjusts the other dimension whenever you change one — so a 1200×800 photo stays perfectly proportioned as you scale it down to 600×400. Uncheck the box only when you intentionally want to stretch or squash the image to exact dimensions.

Frequently asked questions

Is this image resizer free?

Yes. Every tool on ToolsSoup is completely free to use, with no account, sign-up, watermarks, or hidden limits.

Are my images uploaded to a server?

No. All resizing happens locally in your browser using the HTML canvas, so your images are never uploaded, stored, or seen by anyone but you.

Will resizing reduce the quality of my image?

Making an image smaller keeps it sharp. Enlarging an image beyond its original size can look soft, because the browser has to invent new pixels. For the best results, start from the largest version of your image you have.

What image formats are supported?

You can load common formats such as JPG, PNG, and WebP, and export the resized result as PNG, JPEG, or WebP.

How do I make an image a smaller file size?

Reducing the width and height lowers the file size, and exporting as JPEG or WebP compresses photos far more than PNG. Combine smaller dimensions with a JPEG or WebP export to get the lightest file.
