Increase Image Resolution Using 3 Efficient Ways Online/Offline

By Caroline Wilson Apr 24, 2024 Edit Image

Have you ever attempted to expand a photo that was taken at a low resolution? If so, you are aware of how frequently distorted and fuzzy the resulting image is. The reason for this is that low-resolution pictures have fewer pixels, which prevents them from accurately capturing all the little details found in the original picture. Photos are becoming a vital component in advertising and marketing. Written content is less likely to be trusted by people than visual content.

For this reason, you must optimize your photographs so that they can be viewed on the web. With that being said, here comes the image AI upscaler to solve the problem. It can increase your images with just one click! So, without further ado, let’s check these 3 options you can use to increase the resolution of images online and for desktop.

Option 1. Use GIMP to Increase Image Resolution

If you are looking for offline software to increase the resolution of your images that are accessible on your desktop, try to use GIMP. Known as GNU Image Manipulation Program, GIMP is a cross-platform image editor compatible with Windows, macOS, Linux, and other operating systems. The software is available for free, and you can modify and share its source code. GIMP offers you advanced tools to complete your tasks, regardless of your profession—graphic design, photography, illustration, or science. However, it may be hard for beginners to utilize the software due to its complex interface, and it might overwhelm new users. Nonetheless, if that still works for you, here’s the guide on how to increase the resolution of images using GIMP:

Step 1

Open the image in GIMP by selecting the File tab. Select the Open tab, and a pop-up folder will open. Choose the image you want to edit and click the Open button.

GIMP Open Image
Step 2

After that, click the Image tab and choose the Scale Image in the drop-down options. A new window will pop up. In the Width and Height fields, type the new dimensions you want for your image.

GIMP Select Scale Image
Step 3

Click on the interpolation methods and choose from the options given, such as None, Linear, Cubic, or Sinc. Click the Scale button to apply the changes.

Step 4

Once you’re satisfied with the result, download the photo by going to the File tab and selecting Save in the options. And that’s it! Those are the steps on how to use GIMP to increase image resolution.

Option 2. Increase Image Resolution Using Photoshop

Suppose you are looking for a tool that can increase the resolution of an image that is much more professional than GIMP. In that case, you can try Photoshop. One of its plethora of features is the ability to increase the resolution of your pictures by changing how many of those pixels will be displayed per inch. The more pixels an image starts with, the higher the resolution. It will become more apparent as we continue to adjust the image’s resolution. However, since Photoshop is designed with abundant features, make sure to have a good amount of processing power and storage available on your computer. So, how do you use Photoshop to increase the resolution of an image? Here are the steps you must follow:

Step 1

Once the picture is opened in Photoshop, look for the size of your image by opening the image size dialogue box. Go to the Image tab and choose the Image size in the dropdown menu.

Photoshop Select Image Size
Step 2

Change the image size according to what you prefer. You can change the width and height of pixel dimensions. You can also pick one of the preset sizes by clicking the Fit To tab.

Photoshop Adjust the Scale
Step 3

Select the resampling mode by clicking the Resample tab. It will decide which algorithm Photoshop uses to add new pixels, and there are a lot of options available to choose from.

Step 4

Click the OK button once done to apply the changes. And that’s it! Those are the steps on how to increase the resolution of an image using Photoshop.

Part 3. FAQs About Image Resolution

What is image resolution?

The number of pixels shown per inch of a picture is known as PPI, and it is commonly used to define image resolution. A crisper, higher-quality image is produced when there are more pixels per inch (PPI) at a given resolution. It increases pixel information. In lower-resolution images, there are fewer pixels, and those pixels may show up if they are overly big (which commonly happens when an image is stretched).

Can I enhance a JPEG image resolution online?

Absolutely, yes! A JPEG can be high resolution and be done online. In converting a JPEG image into high resolution, it is best to use an image upscaling tool like the Arkthinker Online Image Upscaler. It can upscale the photo even up to 8× without destroying the image quality.

How do I know the image resolution?

Right-click the image on your computer, click the Properties option, and a window containing the image's details will open. To view the image's size and resolution, select the Details tab.


To sum up, those are the 3 efficient ways on how to increase the resolution of PNG images online and on a desktop.
