How to Resize an Image without Losing Quality (Offline)

First, download and install Adobe Photoshop. Then follow these steps.

Launch Photoshop on your computer, go to Files on the toolbar and select Open from the dropdown menu.

Untitled 197

Your device storage will open.

Locate the image you want to resize and click the Open button to open in Photoshop.

Untitled 201

Once the image opens, go to Image on the toolbar and select Image Size from the dropdown.

Untitled 166

The Image Size dialogue box will open. Now you can change the width and height of the image to what you want.

Before any other thing, uncheck the Resample Image box.

Untitled 206

What this does is it tells photoshop not to change the number of pixels in your image. Thus, the image quality and size will remain unaltered.

Next, select the unit of measurement under Document size.

Pixels will no longer be available since you uncheck the Resample image box.

Select any unit you want to use and input the height or width of the image. Changing either will automatically resize the other.

Once you are done, click the OK button to resize your image.

Using Microsoft Paint to Resize an Image

With Microsoft Paint, you can resize images without losing quality using its Resize and Skew feature.

Follow these steps to do it.

Press the Windows Icon on your keyboard,  type Microsoft Paint into the search box and select the Best Match result.

Microsoft Paint will open. Go to File on the top bar and select Open from the dropdown.

Your device storage will open. Locate the image file you want to resize and click the Open button to upload.

Once the image appears in the Paint Canvas, go to the Image Section on the toolbar and select the Resize Icon from the options.

Untitled 155

The Resize and Skew window will pop up.

Select a unit of measurement, Percentage or Pixels and make sure the Chain Icon between the Vertical and Horizontal fields is connected and blued.

Now change the width or height of the image.

The other will adjust accordingly. And if you like, you can stretch the image along the vertical or horizontal axis using the Skew menu.

Lastly, click the OK button, and you’ve successfully resized your image without losing quality.

Using GIMP to Resize an Image

The third software that you can use to resize an image without losing quality is GIMP. Let’s see how.

After downloading and installing GIMP, launch the app on your computer.

Go to File on the menu bar. Select Open from the dropdown and load the image you want to resize.

Once the image opens, go to Image on the top bar and select Scale Image from the menu. The Scale image window will open.

On the Scale image dialogue box, ensure the Chain icon between the image Width and height is connected.

This will lock the aspect ratio and help prevent image distortion.

Next, select a unit of measurement, then change the width or height of your image.

Since the aspect ratio is locked, changing either dimension will automatically update the other.

Untitled 224

Leave the Interpolation under Quality as it is, Cubic. And lastly, click the Scale button to resize your image.

That’s all. You’ve resized your image without compromising the quality.

If you don’t have Photoshop, GIMP or Microsoft Paint and don’t want to install them, you can still resize images without losing quality using an online tool. We’ll walk you through that next.
