Sometimes, reducing the size of an image is necessary. High-resolution original images can take up a lot of space on your computer or mobile device, potentially slowing performance and causing storage issues. While larger photos often mean 'high quality,' it's important to note that a picture's size does relate to its quality to some extent. However, you can often reduce the file size without significantly compromising the photo's visual quality.
So, how can you make an image smaller in file size, and what is the purpose? And how do you use a photo editor for this?
Understanding Image Compression and Its Benefits
Image compression is the process of reducing the file size of an image, which can be achieved through various techniques. It plays a crucial role in digital image management and has both advantages and disadvantages.
Reducing a file's size is often necessary for various reasons. Here are some of them:
To free up disk space: You want valuable storage space, but files take almost everything. You can easily reduce the size of an image and free up some space. At this point, it is also worth mentioning that you should definitely choose the best photo organization software.
For easier file sharing: You want to upload a photo as an attachment (email or otherwise), but the file size is too big to attach. Reduced file size would allow you to upload the file easily and quickly.
For website optimization: You want to upload the image to your website, but the big size is not only taking up space but also causing the website to load slowly.
Next, we will look at several ways on how to resize an image.

Changing Picture Dimensions for Smaller File Size
The best way to reduce the size of an image is to lower its dimensions. You can usually go to your image editing software and select Resize Image from the menu bar.
The dimension of a photo refers to its width and height, which together determine the overall size and shape of the picture. You’ll then be able to adjust the width and the height of the image as per your needs.
Changing Image Resolution to Reduce Photo Size
How to reduce photo size this way? There is one more great option. Besides changing the width and height of an image, you can also reduce its size by altering its dimensions. The resolution of an image is defined by DPI or Dots Per Inch. On a PC screen, the maximum number of dots per inch you see is 72. Larger images are said to have an increased DPI. So, all you need to do is decrease the DPI according to your needs or to 72 to reduce photo sizes. You can perform this task simply by using any of the image editing tools.
Choosing the Right File Extension to Decrease Image Size
How to reduce image size? Changing the extension of a file can help you save a lot of space. Some files such as .PNG and .BMP are generally bigger. Saving the file as a .JPG can be of help.
All you have to do is open the file on a software, choose Save As…, and select .JPG or .JPG when saving the file.
Software Solutions: Making Photo File Size Smaller
Photoshop: You can reduce the size of an image by using the Image Size option. Once you click on the option to resize the image, it will ask you for a new height, width, and resolution. Type in the new values and click save to have a smaller file. It's as easy as that.
Lightroom: You can reduce the file size of an image during the export process. When exporting, simply adjust the dimensions and resolution in the Image Sizing section. You can also set a maximum file size if needed.
Online Tools: TinyPNG and JPEG-Optimizer are websites where compressed images have a reasonable level of quality. Their easy use doesn’t involve software installation.
Free Software: You can also make your pictures smaller using some of the free alternatives to Photoshop.
Tips on How to Reduce the MB Size of a Photo
