A compressed file will never be an exact copy of the original, with some exceptions. But with this almost always there is a loss in quality since the main compression algorithm is to select several pixels and replace them with one or two similar in shade. Because compression can very effectively minimize the size of the images just twice or several times. There are quite a few types of compression schemes, but the essence of their existence can be reduced to one task – to compress image to a specific size and we are talking about the bitmap file as efficiently as possible. However, we are more interested in bitmap formats as we often have to deal with them and namely why to optimize photo when uploading it to the Internet.īesides that, image file formats can be distinguished based on compression effects. Surely everyone came across them because many e-books and documents are stored in PDF-format. The most famous example of such a format is. Complex formats, as it appears from the name, have features of both vector and bitmap images. Vector images are based on geometric shapes – points, curves, circles, polygons. In general, image formats can be divided into 3 large groups – bitmap, vector, mixed or complex. There are countless image formats, and from time to time new ones also appear. Some formats are best suited for obtaining the optimal balance of quality and file size when storing your photos, while other types will make it easier for you to recover a damaged image. This article is aimed to shed light upon such topics as “How to compress image sizes” as well as “What is compression”.įirst of all, the understanding which image format to use will give you the opportunity to get the most out of it.
However, everything is not so difficult as it may seem for the first time. Why to optimize photo? Or simply why to compress image to a specific size? What is compression and when you should use it? These difficult questions can scare a lot of the users.
