The vast majority of modern society has long been actively using social networks for communication, development, recreation, and old friends or just acquaintances. Watching the events of other people's lives, unwittingly everyone wants to share their own adventures.
However, even the most successful frames are not tested on your favorite sites: the size or weight of the image exceeds the maximum limit. And users are storming the search engine, trying to figure out how to reduce the size of the jpg-file.
The first links often lead to third-party resources that offer to upload an image to a server and compress it online. But in such cases, the quality of photographs suffers significantly.
But how to reduce the size of the jpg-file and not get a photo in the end, in which the pixels will be clearly visible? First of all, it is worth understanding what the weight and size of the image is.
Image resolution and size
Users who are not related to work with graphic editors often confuse such basic concepts as resolution and image size. Trying to understand how to reduce the size of a jpg-file, many change the resolution and vice versa.
The size of a photo or image is the physical manifestation of a picture, that is, the size in centimeters, millimeters, inches, etc.
Image resolution is a well-defined number of pixels per inch. It is measured linearly - the number of points in one straight line.
Image resolution data is provided by manufacturers of cameras and photographic equipment: from 320x240 to 7680x4800. The higher the resolution of the camera, the clearer and better the photos or video will be.
It should be noted that when changing the physical data of the image - the size - the number of pixels will remain constant, but they will stretch over a larger space. Thus, the clarity of the picture will be lost. By reducing the size of the photo, but without changing the resolution, you can make the picture more qualitative.

In order to change the weight or resolution of a photo in Photoshop, you need to open the file in the graphical editor and click on the “Image” menu. Next, find the item "Image Size".
Below the already known parameters that define the width and height, is the line "Resolution". This parameter is measured in pixels per inch, or in pixels per centimeter.

Change the weight of the photo in Paint

To change the size, just open such an image in the editor and, choosing “Save As” in the menu, change the format to JPG. In most cases, the weight of the photo immediately decreases several times.
