Increase or Change Image Resolution with Image Resizers

Before we get into details, the core question is: do you only want to change the resolution of the image (in terms of the pixel value shown in width and height), or do you prefer to truly increase the image quality and achieve a higher resolution?

In fact, altering image resolution (the dimension expressed in number) is simple, whereas increasing image resolution for better clarity without quality loss can be tricky. You'll want a smart image upscaler instead of an image resizer to avoid possible distortion.

Depending on your specific scenarios, you can use the following tools whichever suits your needs.

Quick Solution: Aiarty Image Enhancer is a simple yet versatile AI image upscaler. It uses CNN and deep learning to create new pixels that seamlessly blend in with the original image. Only in a few mouse clicks, you can dramatically increase image resolution with AI while keeping image quality.

How to Change Image Resolution in Photoshop

Adobe Photoshop is a powerful image editor widely used by photographers, graphic designers, and digital artists. If you want to finely change image resolution rather than simply zooming in and out of pixels, it's your best choice. It provides various tools for manipulating images, including adjusting their resolution.

Here's how to change image resolution in Photoshop.

1. Open your image in Photoshop.
2. Go to "Image" > "Image Size" to bring up the Image Size dialog box with Width, Height, and Resolution settings.
3. Type a new value into the Resolution field to change image resolution: increase image resolution or lower image resolution.
4. Ensure Resample is unchecked to maintain the current number of pixels.
5. If you need to adjust dimensions for print, check Resample and choose an interpolation method such as Bicubic Smoother or Preserve Details.
6. After making your adjustments, click OK to apply the changes.
7. Click "File" > "Save As" to save the adjusted image.

Resample: When checking the Resample option by default, Photoshop will adjust image dimensions by increasing (upsampling) or decreasing (downsampling) pixels from the Width and Height. When unchecked, Photoshop will resize or change image resolution by redistributing existing pixels.

PPI: Traditionally, 72 ppi is the go-to resolution for screen use, while 300 ppi is the standard for print.

Here's how to change image resolution in Canva.

1. Open Canva and create a design in your desired image resolution.
2. Upload the image then drag and drop it to your project.
3. Click and select the image.
4. Go to Position > Arrange > Advanced on the top toolbar.
5. Enter the pixel values in the Width and Height fields.
6. You can also drag the resize handles when locking the Ratio to keep its proportion.
7. Click Share to download the resized image or post directly on social media.

Increase Image Resolution with AI for Better Quality

Blowing up pixels may not necessarily enhance image quality at a higher resolution. For instance, a 512x512 image being stretched to 1204x1204 won’t restore details if the tool is simply duplicating pixels or interpolating with traditional mathematical algorithms.

You'll want a smart image upscaler instead of an image resizer to avoid possible distortion. That's where AI and machine learning come in handy.

Aiarty Image Enhancer is a simple yet versatile AI image upscaler. With 6.78 million image training dataset, which contains various image types, such as anime, photography, illustrations, CGI, and more, and specific AI models, this AI image enhancer can change image resolution while restoring details, and avoid an artificial look.
