While the user processes the photograph created by him, it may be necessary to reduce weight photos for subsequent storage on a carrier or for the bay to various services, social. Networks and forums. In most cases, smaller photographs are achieved in two ways - image compression and by converting. But how to do it with minimal loss of quality? Let's try to figure out.
1
For conversion, the XNView program is perfect. It includes a considerable number of useful features, but we will focus on converting files.
2
Conversion is a change in the file format. Why do you need it? Let us give a simple example: if the original format was in the PNG extension, then converting it into a more "light" JPEG format, we get a photo with a reduced size. The quality of the material will also be reduced. It should be remembered that a significant reduction in size will always entail a deterioration in image quality. As far as it is "tangible" and striking, depends on the selected programs.
3
As an example, take a simple image with the name "sovetclub.ru" located in the image folder. Open XnView and find the desired directory.
4
As we see, the size of the source file "sovetclub.ru" format "PNG" is 1.21 MB. Our goal is to convert it to JPEG format, thereby reducing its weight. You press the right button on the file, in the submenu released, select the "Convert to" item - "JPEG".
5
As a result, we get an image with a much less weight. The size of the destination file is 144.50 KB.
6
Of course, the image shown as an example has a slight resolution and weight. When converting photos, the final file can weigh and more, but nevertheless, the difference will be tangible. You should experiment with file formats and specify the most suitable for you. The most priority is the format "JPEG".
7
To reduce the weight of the file, you can use compression. This is the most acceptable way used by most users. To do this, we use the Faststone Image Viewer program with the image compression function. The quality of photography at the output is not afforded, but compression is due to the reduction in image resolution.
8
We open the program and for example, we take the same file "sovetclub.ru", weighing 1.21 MB, in the folder "Images".
9
On the top panel, choose the "Change Size" icon.
10
By clicking on it, a window opens with compression parameters.
11
You can resize by specifying the number of pixels or percentage ratio.
12
For example, specifying the percentage - 50, the image resolution will be 512 × 384. The file size will take 124 kb.
Based on the above, it can be said that most users use these methods to reduce the weight of their photos. You can find a third-party program and squeeze an image while saving the image resolution. But in this case, the quality of photography will suffer, and the higher the compression ratio, the "more visible" it will be on it.
