Resize Image Dimensions Online

Set the width and the height the destination asks for and this page resamples the image onto those dimensions inside your browser. Nothing is uploaded, so a batch can run over files you would not send to a server, and the result reports both its dimensions and its file weight.

Frequently Asked Questions About Resize Image Dimensions Online

How do I resize an image to exact dimensions?

Enter the target width and height, choose fill or fit, and download the result on that frame.

Will resizing change my file size?

In both directions: fewer pixels usually mean a lighter file, while enlarging a small source produces a heavier but softer one.

Will my original file be changed?

The result is downloaded as a separate file. Keep your original until you have checked the Custom width and height.

What should I check before using the result?

Open the Custom width and height in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.

About this workflow

Sizing for a slot you were given

When a template, a CMS field or a print sheet names the dimensions, resize to them here and check the row preview before you run the rest of the set.

Before downloading the result

Open the Custom width and height next to the original at full size and check text edges, faces, and flat backgrounds; re-encoding softens detail long before it looks wrong in a thumbnail.
