The problem of how to reduce the weight of the photo is faced by each user of the network. Lightweight photos load faster on websites, easier to send by mail, and not everywhere you can attach an image in high quality - restrictions hamper.
Firstly, to reduce weight, you can reduce the size of the photo, cut off the unnecessary part. This, of course, is not a way out of any situations, but you should not forget about the opportunity. Especially when you need to keep within a very limited framework for weight and quality. You have to sacrifice something else.
You can reduce the weight of a photo in almost any editor, including Paint. But if you want to achieve good quality (not to lose existing), it is better to use more advanced software.
Some images have to be processed only by specialized programs or editors. This applies to high-resolution photographs and images in which a gradient background and contrasting objects converge on the border. If you do not use good compression algorithms, artifacts appear in such images when reducing weight. (The most famous JPEG artifact is blur.)
The most popular programs used to reduce the image without losing quality include Photoshop, ACDSee, and the free Gimp and Inkscape (the last of these is the best alternative to Photoshop). In the corresponding dialog, you will be asked to choose which compression should be applied - maximum or with preservation of quality. Using the rulers, you can choose the best option.
There are special programs that can do nothing more than reduce the weight of the photo. But with the help of image preview you can choose the most optimal process settings. An example of such a program is Caesium.
Recently, a lot of services have appeared on the Internet that help you create or edit an image using the WYSWUG editor. So, the service JPEGmini.com helps to get "thin" images, it would seem, unchanged. He solves the problem of how to reduce the weight of a photo, say, for those who did not take a laptop on a trip, but decided to share fresh photos before returning home.
Unfortunately, most of these services often do not justify all the hopes placed on them. For example, not all uploaded photos will be returned to the user in a reduced form. Therefore, it does not hurt to know how to reduce the weight of photos using regular Windows tools.
On any computer, a package of office programs from Microsoft must be installed, and in it, in addition to Word and Excel, there is a Picture Manager. In the "All Programs" list, it is hidden under the item "Microsoft Office Tools", and in some versions it translates as "Picture Manager." Run the program, add the shortcut of the desired photo through the “File” menu, and in the “Picture” menu, find the item “Compress Pictures”. There are 4 compression modes to choose from: for sending by mail, publishing on the web, posting in documents and for exiting the program without compressing the picture.
PictureManager allows you to reduce the weight of the image tens of times, leaving its quality acceptable. The program, of course, can not be compared with professional packages for image processing, but for everyday needs its capabilities are enough.
