As we all know, compressing the size of a picture is usually at the cost of losing the quality of the picture.

Method 2 Shrink Image File Size by Changing Image Format

JPEG and PNG are two familiar image formats. Generally, JPEG images have smaller files and larger palettes; The PNG image file is larger because it supports unlimited colors. If the picture itself has few colors, you can reduce its size by converting it to JPEG format. The operation is very simple. Click the image to find "Modify the format". It should be noted that sometimes format conversion may result in loss of image quality.

Method 3 Reduce Photo File Size by Changing Image Resolution

Image resolution is also one of the factors that affect the size of image files. For example, a 1820 x 1180 image must be larger than a 980 x 760 resolution image. Therefore, to compress the image size, you can also reduce the image resolution without damaging the image quality. Many image processing applications, such as Photoshop and Paint, provide the function of modifying image resolution, in which you can directly input resolution values (pixels).

Method 4 Reduce Photo File Size by Reducing Color Depth

Photoshop provides different image formats for users to choose. Because of different image formats, color compatibility is different, and the size of the images presented is also different. You can set the image to a smaller format by following the steps below.

Step1 Open the picture with Photoshop, and then click the image to enter the mode.

Step 2 Select the mode according to your needs. The image in "RGB Color" format is larger than the image file in "Indexed Color" format, and "8 Bits/Channel" represents the smallest file size.

It is important to note that reducing the color will change the quality of the photo. Therefore, if you are very concerned about the quality of the compressed image, we do not recommend that you use this method.

Method 5 Make Image Size Smaller by Cropping Image

One of the easiest ways to shrink an image is to crop it using Paint, an image editing program that comes with Windows. The specific steps are as follows:

Step1 Open the picture to be processed with Paint.

Step2 Click the Home tab > Image > Select.

Step3 Adjust the dotted box around the image to determine the desired size.

Step4 Right-click the selected area and choose "Crop" to save the cropped image.
