Modern matrix cameras allow you to shootphotos incredibly high resolution, which, in turn, increases the size of the picture. This could be tolerated if most of the photos taken were not uploaded to the Web. Unfortunately, many sites seriously limit the size of uploaded images or automatically create small copies, making the pictures much lower in quality. This raises the question of how to reduce the size of the photo, saving the maximum color information.
There are several ways to reduce the photo:
If you process a large number of picturesin Lightroom, you can use the export settings. In this program, of course, there is a built-in converter, which can reduce the size of the photo both during storage and in the process of working on them. In the export window, it is enough to set only the size of the wide side of the photo and watch the program itself optimize the images in size.
Adobe Photoshop also has a built-inconverter, which allows both to reduce the photo, and to stretch them. To do this, open the image size menu by pressing the key combination Ctrl + Alt + I and select the desired values for the future picture. There are no complicated settings in the window, so we will not stop at each point.
To reduce the weight of the photos, the compression is dividedon several types: lossless compression and loss. When you reduce the size of a photo without losing quality, it is usually less noticeable to the eye and can be used for pictures with any content, especially for those where the integrity of the picture is important. With this compression format, you can not drastically change the size of the picture.
Lossy compression is preferably used for small, abstract and average quality images. The size can be significantly reduced, but at the same time a significant part of the image information is lost.
Typically, for cropping photos use the secondmethod. Weight reduction is achieved by subtracting different garbage data, for example, duplicated or too light pixels, replacing pixels with numerical values and cutting out unnecessary information. In any case, the photo reduces not only in weight, but also in quality. Although it is worth noting that the deterioration in quality is directly proportional to the reduction size obtained. But how to reduce the photo without losing quality and whether it is realistic to do this without third-party programs?
There are converters that do the workreally qualitatively and almost imperceptibly for visual perception. Nevertheless, it is possible to reduce the size of a photo without loss of quality only with a slight weight cut. If you want to optimize the picture to the maximum, you will have to choose such compression values, under which the quality remains acceptable.
However, greatly reduce the size of the pictures usefulonly if you download them to the network, to save space on servers and speed up the loading of sites. For simple storage on a home PC, extra file size reduction does not play a significant role.
The easiest way to reduce the image -cut down its physical size. This does not require the presence of any special programs or third-party services. You can use the old good editor Paint. In order to reduce the size of the photo, as in the previous case, we perform several simple manipulations:
Many sites set a limit forinput files up to 1 MB. Reduce the size of the photo both in physical size and weight will be the most correct option to achieve the desired result. For example, you can crop a part of the image in the editor, and after that, you can also compress it to the maximum.
Although 1 MB for pictures is enough to store a lot of information, photos with the original size of several thousand pixels can still not fit into these limits.
The network has a wonderful service calledOptimizilla, which can compress files to a record low. For example, the original photo size of 3.5 MB, loses 90% of the weight at a quality of 70%, which practically does not worsen the picture. The converter copes with large images effectively, but it's better not to upload too large photos, as reducing the photo size to 1 MB from the original 20 MB is quite problematic in any case.
