How to Change DPI of an Image: A Comprehensive Guide

Image printing is important for social events and gatherings to feel more inviting and welcoming to its attendees. Additionally, these banners also provide clarity for the invited people to easily understand what is the event that is being celebrated. With that in mind, the dots per inch or DPI of an image is important for printed banners since it has an important role; moreover, low-quality printed materials may provide the opposite of the message that it was meant to convey. In this article, we will learn multiple ways to learn how to change DPI of an image to make a banner that will be high quality and appealing for any form of social event. Please read the article below to learn more about this topic.

Part 1. Image DPI vs Pixels

Before proceeding to our main topic, let us first define what exactly is an image's dots per inch (DPI) and what is its difference when compared to pixels. To start, DPI is a type of printing setting that defines the amount of dots that will be applied in a single inch of the material that will be printed into. On the other hand, pixels are digital dots that also define the quality of a digital photo. In a way, the two measurements are similar except for the platform where they will be used. DPI is for physical printing and pixels are for digital images.

If you change the DPI of an image file, its printed quality will be affected depending on your adjustment settings. Because of that, images that will be used for printed banners, flyers, tarpaulins, clothes, and dining equipment must have high DPI to ensure that the image quality will be preserved. 300DPI is the safe threshold that most designers and photographers use as a standard.

DPI is different from PPI, and get more information about how to change image pixels here.

Part 2. How to Change DPI of Image

1 Adobe Photoshop

We will start this section of the article by featuring the most famous photo editor software for both Windows and macOS platforms with Adobe Photoshop, the pioneer editing tool built for images available in Adobe Creative Suite.

Since this tool is primarily made for photo editing and is considered the standard software of designers alike, changing image DPI in this tool was made simple by its developers. As an additional convenience feature, the DPI can also be adjusted together with the size of the photo that is being edited.

To learn how to change image DPI using Photoshop, a quick three-step guide will be featured below:

1. Open Adobe Photoshop and add the file that you want to adjust the image DPI.

2. After adding the file, select the Image tab and then click on Image Size.

3. In the Image Size editor, select Resolution and change its value depending on where the image will be used. Click OK to confirm your setting.

By using the image size editor of Photoshop, you can now change the DPI of the image that you are editing and adjust its size and resolution in one go. Moreover, changing the DPI of image files on this editing tool is relatively easy when compared to other features also available in Photoshop.

2 Clideo Online Tool

The next option for DPI changing that we will present is Clideo’s DPI Converter tool, an online tool that can change DPI right after uploading the file that needs to be edited. Since it is an online service, Clideo does not need to be installed which can save a lot of time for express DPI changing. However, its online nature also limits its convenience since the tool can only be accessed with a stable connection.

To learn how to use the Clideo DPI converter, please read our quick guide below:

1. Search for Clideo DPI Converter on your browser.

2. In the site’s main interface, click Choose File to add the image that you want to convert.

3. Set the DPI that you want to apply. Then, click on Continue to start the conversion process.

4. In the next window, click the Download button to save the edited image back on your computer.

Clideo is one of the most trusted multimedia editing tools across the online market. Because of that, their DPI converter is also well-received and trusted by their loyal consumers. However, their process is slightly slower than other services.

3 Pi7 Image Tool

We will stick with online tools for the third option in this section with Pi7 Image Tool, a more straightforward option than Clideo since this site is exclusively built for processing image files. This is also the reason why it can change image DPI faster and more efficiently unlike Clideo where the conversion process takes almost a minute.

Please follow our guide below to learn how to use the Pi7 Image Tool as an image DPI converter:

1. Search for Pi7 Image Tool.

2. On Pi7’s site, select the Convert DPI option.

3. Next, click on Select Images or drag the photo that you want to change the DPI into the drop box.

4. You can change the DPI value on the designated tab if you want higher quality than the standard 300. Otherwise, click Convert DPI to start the process.

5. Simply click on Download to save the image with adjusted DPI back into your computer.

Pi7 might have more steps when compared to Clideo, however, it is easier to use since it can process images much more efficiently. This heavily outweighs the additional steps required to use this tool.

Part 3. How to Check DPI of Image

To learn if the DPI of your image needs to be changed, the first step is to know how to tell the DPI of an image first since it will verify the need for a DPI change. Fortunately, this process does not require any third-party tools since the DPI of an image can be seen on the properties of the file.

To learn how to check the DPI value of your image, please refer to our guide below:

1. Locate the image that you want to check and right-click on it. Select Properties on the list.

2. In the properties window, select Details.

3. Under Details, scroll down and look for the DPI value labeled horizontal and vertical resolution.

Now that you know how to determine DPI of an image, building a habit of checking it first before printing an image is a good quality control routine. By ensuring that the DPI of your image at least follows the 300 DPI standard, you can ensure that the visual quality of printed images will be high.
