How to compress a picture with a picture compression tool Imageoptimizer

Today's mass storage card, mobile hard drive has enabled us to avoid the limited number of photos taken. But as a non-publishing use, on the Internet and the exchange of photos, need to size as small as possible, but the quality can not be very poor. Too large a picture on the page will slow down the visitor's download speed, affect browsing. At this point, we need to use image compression processing software to reduce the image weight loss, remove the redundant information. The

Image Optimizer is the leader in the picture optimization tool. It and JPEG optimizer is the same company produced software, the latter is for JPEG format images, and image optimizer can be jpg, GIF, PNG, BMP, TIF and other image files for compression optimization, the application of a wider range. It can not affect the image quality of the image to lose weight, the highest can be more than 50% thin body. Image optimizer allows users to control the optimization process, in addition to the compression rate can be set, but also with the real-time preview function, you can instantly preview the image compression quality. In addition, you can use the built-in Batch wizard to optimize a large number of image files at once.

Implementation principle

Image Editing Tool is the most famous in Photoshop, but it is processed by the JPG image size is still very large, then image Optimizer is how to make the image size greatly reduced, and the quality of the basic unchanged? This has to do with its unique principle of realization.

Image Optimizer and other graphics editing software is the biggest difference is that it can be based on the color area of the picture "because of color compression", white point is less color where more compression, more color less compression, in order to change the approximate quality under the smaller picture volume. Therefore, when the other image editing software or compression of the picture with a uniform ratio, the advantages of image optimizer is naturally reflected, which is the most important reason it can overcome some professional image software.

Optimize a picture

You can open a picture that needs to be optimized by clicking the Open button on the toolbar, or by dragging and dropping the image document from the folder to the edit window in Image optimizer (Figure 1). Click the "Optimize Image" button on the left to see the image Optimizer opens a new window (Figure 2) with optimized images. The Compress Image dialog box opens. At the top of the newly opened optimized image window you can see the size of the optimized image file: After the optimized picture size has been reduced a lot, optimized (BMP format) is 2329 KB, optimized (JPG format) for the KB, the effect is amazing, and the quality of the picture is not significantly reduced. In the Compress Images dialog box, we can select the format of the output file, and depending on the format, you can also manually select the compression ratio (for JPG format) or the number of colors (for GIF and PNG format) for better compression. At this point, the status bar in the lower right corner of the program window can also see the current image file using the 28.8Kbps demodulator to download the time required, which is helpful for web designers.
