How to resize an image




Use our free online tool to not only change image formats, but to resize them as well. If the selector is set to "scale" instead of stretch, it will not change the shape of your image but will scale it to fit in the dimensions you specify in the height and width fields. If you click the "stretch" radio button, it will stretch your image to fit EXACTLY the dimensions you specify. Try it!

Resize Image Online

Once you have mastered the basics of image manipulation, it is quite easy to resize an image. The two best ways for visitors of this site are by using either the Gimp, or MS Paint.

MS Paint

You probably already have MS Paint installed in your PC, so no need to download or purchase any software. With MS Paint, there are some limitations. You cannot choose a pixel size for your image, nor a compression factor... you resize by percentages.

So if you would like to convert a 500px wide image to a 300px wide image, you need to resize it by 60%. This method takes some guesswork if you are trying to fit an image into a fixed width web page column.

The Gimp

The Gimp allows you to resize images in a number of different ways.

  • You can choose a pixel width or height and it will automatically scale.
  • You can use the stretch tool. If you select it and hold down the CTRL key while stretching, the image maintains its proportions (height vs width).

So if you would like to convert a 500px wide image to a 300px wide image, you need to resize it by 60%. This method takes some guesswork if you are trying to fit an image into a fixed width web page column.

What is The Gimp? The Gimp

GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. It can do almost anything that the commercial package "Photoshop" can do, but best of all, "The Gimp" is FREE. That's right, it is open source software that you can download for free and use immediately.

Where to get the gimp and how to get started:
