Fortunately, there's an easy solution: Photoshop. Photoshop is a powerful tool used for modifying images. It's versatile enough for tasks like resizing images and more complex functions like retouching photos.

So, in this easy guide, we'll show you how to resize images in Photoshop without losing quality.

Part 1: How to describe an image size

When dealing with digital images, it's important to know the difference between file size, dimensions, and resolution.

  • File size refers to the amount of digital data (in bytes) the image takes up on a device or storage medium.
  • Dimensions refer to the image size measured in pixels with respect to both its width and height.
  • Resolution refers to the total number of pixels that it contains.

With this information, you can ensure that your files are optimized for online or printing. For example, an image that is 1200 pixels wide and 1800 pixels tall would be described as having dimensions of 1200x1800. Then, with a resolution of 300 PPI (pixel per inch), you can see the file size of the image is 3 MB.

Part 2: When need to resize an image

At times, people may need to enlarge an image size. It can be done for several reasons, including:

  • You need to print the image out and the current resolution is too low
    The image must have a high resolution to get a high-quality print. Otherwise, the quality of the image will be poor. To increase the resolution, you need to increase the size of the image.
  • The image is being used for a presentation and it needs to be enlarged
    By resizing the image, you can set the image size precisely to what you need.
  • You want to blow up the image to frame it or hang it on the wall
    If you're planning to blow up an image to frame it or hang it on the wall, it's important to get the sizing right. Otherwise, you'll be disappointed with the results.

On the contrary, there are several reasons why you may need to decrease the size or resolution of your images:

  • Save storage space on your device
    By saving your images in a lower resolution, it will also reduce the file size
  • Send a photo via email or text message
    When sending a photo via email or text message, it is important to decrease the image size. It is because large images can take up a lot of space and cause the email or message to take longer to send.
  • You need to upload an image to a website or social media platform
    A website or social media usually has a specified maximum size or resolution in their requirements. Therefore, you need to decrease the size of your images.
