How do I reduce the JPG file

Usually, users use the maximum compression quality of JPG files. Therefore, these files occupy very large space. Keeping these files on hard disk does not create difficulties. Only in some cases the size of the images must be reduced, even to the detriment of quality.

Two methods to shrink JPG file

1. Reduction of resolution – a reduction in the number of points, from which the image is formed. The resolution is specified in the number of points in length and width. The higher the image resolution, the greater the JPG file and the better the details of the image.
2. Reducing image quality – It is an increased compression, which is used in the coding of the JPG format. The smaller the quality of the image, the smaller the size of the file.

The best way to reduce the size of the JPG file are the two methods described. By reducing the resolution and reducing the image quality you will be able to reduce the size of the file. To do this you will need a graphic editor. I will prove to you how to do the Graphic Editor Adobe Photoshop (I use Adobe Photoshop CS2, because it is free).

1. Open the image with the help of Adobe Photoshop. This you can do through the vertical menu «File – Open» or simply Tragan the image in the program interface.

2. Reduces the resolution. To reduce the image resolution in Adobe Photoshop you will have to open in the vertical menu «Image size».

A window will open with the image size settings. In my case the size of the image is 2048 on 1536 points (pixels).

In the «Width» field it introduces a lower value. For example, 1000 points. The value in the «Height» field will change automatically.

3. We reduce image quality. In order to reduce the image quality, we will have to save it with other settings. For this we open the vertical menu «File – Save as». Then we choose the place where the image will be saved, check the format (it must be JPG) and press the «Save» button. Then a window with compression parameters will open.

To reduce the size of the JPG file we will have to move the cursor to the left, reducing the quality level. As an example, we will reduce the quality level from 8 to 6 points. After the quality level is set, we press the «OK» button and the program will save the image.

As a result, the size of the JPG file decreased from 884 KB to 216 KB. Thus, the chosen file has decreased about 4 times.

Conclusion

JPEG (JPG) files are widely used for storing images due to their ability to compress data while maintaining reasonable visual quality. Most users tend to save images at maximum quality, which preserves details but results in large file sizes. For everyday storage on a hard disk, this is usually not an issue, as modern drives offer ample space. However, in certain situations, such as web publishing, emailing images, or managing large photo libraries, the size of these files can become a challenge.

Reducing the size of JPEG files often requires lowering the compression quality, which may slightly compromise image clarity. This trade-off between file size and quality is important to consider, depending on the intended use. For example, web images or thumbnails do not require maximum resolution, and reducing their size can improve loading times and save bandwidth. Similarly, when sharing images over email or cloud services, smaller file sizes make transfers faster and more efficient.

Users can utilize various tools and software to resize or compress JPEG files effectively, allowing them to maintain a balance between visual quality and storage efficiency. Modern image editors and online services provide easy ways to adjust compression levels, batch process multiple files, and even preview quality changes before saving. Understanding these methods helps users manage storage, optimize performance, and ensure that images remain accessible without occupying unnecessary space.

In conclusion, while JPEG images at maximum quality are ideal for preserving detail, there are practical reasons to reduce file sizes. By carefully managing compression levels, users can save storage space, improve file transfer efficiency, and optimize images for different purposes without significant loss of quality. Balancing size and quality is a key skill for anyone managing digital images effectively.
