Encountering a message like, “Your Image has a smaller file size than we recommend. Use a higher quality image for better print results,” when uploading photos online can be frustrating. This often indicates that your image’s resolution is too low for the intended purpose, especially for printing or displaying on larger screens. Fortunately, you don’t always need professional photo editing software to increase image resolution. Basic programs like Microsoft Paint on Windows and Preview on Mac offer simple ways to adjust your photo’s resolution and improve its quality.
Increasing Image Resolution in Microsoft Paint (Windows)
Microsoft Paint, a standard tool in Windows, can be used to make basic adjustments to image resolution. Here’s how:
-
Open Your Image in Paint: Launch Microsoft Paint. Click on File in the top left corner, and then select Open to browse and choose the image you want to edit from your computer.
-
Access the Resize Tool: Once your image is open in Paint, look for the Resize option in the toolbar, usually located at the top of the window under the Home tab.
-
Adjust Resolution in Pixels: A Resize window will appear. Ensure that Pixels is selected as the unit for resizing. This is crucial for changing resolution.
-
Input New Dimensions: You’ll see fields for Horizontal and Vertical pixels. By increasing these pixel values, you effectively increase the image resolution. Remember to maintain the aspect ratio if desired by checking the “Maintain aspect ratio” box. Enter your desired pixel dimensions and click OK. Increasing the pixel dimensions will also increase the file size of your image.
-
Save Your Adjusted Image: After resizing, go to File and select Save As. Choose your desired file type from options like PNG, BMP, or JPEG. These formats are commonly accepted for online uploads and printing. Saving your image will apply the new resolution settings.

Adjusting Resolution in Preview (Mac)
For Mac users, Preview is a versatile built-in application that can also handle image resolution adjustments. Follow these steps:
-
Open Your Photo with Preview: Find the image file on your Mac and open it with Preview. The default image viewer on macOS is usually Preview.
-
Find the Adjust Size Tool: In the Preview menu at the top of your screen, click on Tools, and then select Adjust Size… from the dropdown menu.
-
Select Custom Size and Resolution Units: In the Adjust Size window, you’ll see a “Fit into” dropdown menu. Choose Custom to manually set the dimensions. You can adjust the width, height, and resolution. Use the dropdown on the right side to select your preferred unit – either inches or pixels – for dimension adjustments.
-
Modify Dimensions and Resolution: Input your desired values for width, height, and resolution (DPI – Dots Per Inch). Increasing the pixel dimensions or DPI will enhance the image resolution. Adjust these settings according to your needs. Click OK to apply the changes.
-
Export Your Edited Image: Go to the File menu and select Export…. This allows you to save the image in various formats such as JPEG, PNG, PDF, or TIFF. Choose a format suitable for your intended use and save the image.
