Part 2. How to Change the DPI of an Image

What if you have to alter the DPI of an image because the requirements of the project in question demand it? Alterations done on the DPI may aim to improve the image quality for printing purposes or reduce image sizes for usage across the web. If you increase the DPI, there will be finer details than if the value is lower; similarly, decreasing the DPI will help compress the image size for use on the digital facility. Below are the practical steps on how you can raise or reduce the DPI of your images.

1. Increase Image DPI

There are scenarios where you are required to increase the DPI of an image. Fortunately, AVAide Image Upscaler comes to the rescue. Besides, whose only mission is to improve image quality and increase the sizes and perfections of the surtout images, this AI-powered tool also comes in handy in raising the DPI when needed for high-quality prints or resolutions.

Detailed Procedure:

Step 1Go to AVAide Image Upscaler and select the Choose a Photo feature to upload the image that needs enhancement.

Step 2After uploading, choose the level of upscaling from 2×, 4×, 6×, or 8×, which will either change the image size or the DPI.

Step 3AVAide has an AI technology where image quality is optimized, blurriness is removed, and details are sharpened as you select the upscale value.

Step 4After upscaling, click Save to download your newly enhanced, high-DPI image to your computer.

Advantages of Increasing Image DPI:

• Improved Print Quality: Arising from high DPI, printed images will always be sharp and well-detailed, bearing the requisite professional quality, especially for large prints.
• Better Clarity: It can be assertively stated that the resolution of the images is greatly improved with a nod to the fact that as the DPI increases, so does the image.
• Preservation of Details: With a higher DPI, the small elements are preserved, which is fundamental in photography and design, so nothing important gets lost.
• Enhanced Viewing Experience: To display on high-resolution digital screens, the impressions of images are further enhanced where the DPI is increased, eliminating pixelation.
• Professional Standards: Many sectors, for instance, publishing and advertising, require high DPI images for professional standards, which leave your work market ready.

2. Decrease Image DPI

Decreasing the DPI image is useful when you need lower image quality, smaller file sizes, or images for web use where high print quality is not required. Adobe Photoshop allows for an easy way to reduce an image's DPI without affecting its dimensions or clarity for digital viewing.

Detailed Procedure:

Step 1Launch Adobe Photoshop, then take the picture by going to >. Go to the top menu and click on Image Size.

Step 2To decrease DPI without changing the pixel dimensions, ensure the Resample checkbox is unchecked.

Step 3If it is required to change both the DPI and the size, see images of smaller sizes. You will check the Resample box and resize it in widths and heights.

Step 4After the appropriate DPI is reduced, click the OK tab, after which go to File Save As and save the edited image.

Advantages of Lowering Image DPI:

• Managing a Picture's Size Effectively: First and foremost, Maiya reduces the dpi, and the file size is lesser; hence, it is more suitable for internet usage or sending to other people.
• Lesser Resolution and DPI: Send an image that has a different dpi for television and magazines but retains the quality of the picture on the screen.
• Non-destructive Editing: Editing pictures in Photoshop reduces the dewy and thus when only, say, 72 dpi is used. This means that when optimizing an image for transmission, the transmission and finer details, such as clipping masks, will not make the image blur or pixelated areas.
