How to compress photos

Usually our digital camera pixel value is very high to tens pixels, and our ordinary personal photos and landscape only need millions of pixels, so the idea is to compress the photo by changing its pixel value to thin body. You can compress photos with professional image processing software Photoshop, ACDSee, and windowns system with drawing tools.

Below I have the figure (original and file attributes) as an example, respectively, using Photoshop, ACDSee and drawing tools three software to illustrate the steps to compress the picture.

Compress with Photoshop

1. Right mouse button to compress the file, click Photoshop in the pop-up window.

2. Menu Image->image Size in open Photoshop

3. In the Pop-up Image Size dialog box, you can modify the image pixel or image size size, pixel/image size smaller, the capacity of the photo is naturally small, and then click OK button.

4. Then see if the size of the photo is appropriate, and if it feels wrong, you can continue to repeat the above steps until you are satisfied. Finally, press the Ctrl+s fast key, pop-up JPEG Options dialog box, you can adjust the red wireframe parameters or slider to adjust the compression ratio, to further thin the picture, and then click the OK button to save the picture.
