This is called lossy compression. this is best way to reduce the size of the images so it can help you save the image by using less memory.

This format stores an image by storing the individual values for each pixel. These values define how much red, green, and blue colour there is in a pixel. They also store the location of the pixel.
As a result of this, an image save in this format will have a fixed resolution, which means that if the picture were to be enlarged or zoomed in, it would look pixelated. 
Furthermore, pixelation is ]]> 2016-09-21 13:52:53 UTC https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125401667 Lossless Compression radoslavx25 https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125402096 Lossless compression reduces a file's size without losing its quality. This can be applied to both image and audio files. While JPEGs and MP3s use lossy compression, newer compression alogrithms, such as JPEG 2000 and Apple Lossless compression, can be used to create lossless compressed files. 
Lossless compression rewrites the data of the original file in a more efficient way. Since there is no quality loss, the resulting files are typically much larger than image and audio files compressed with lossy compression.]]> 2016-09-21 13:53:44 UTC https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125402096 Compression  karan1999desai https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125403727
Compression means to reduce the size of a data file for example a document, spreadsheet, image, sound file etc. It is a good idea to compress large files because they can take up a lot of storage space on your hard disk. They will also take a long time to send as an attachment by email.Before you can use a compressed file, you must uncompress it.Compression is usually carried out by using a piece of utility software such as 'WinZip'.

These formulae are processed by image viewers in order to create various geometric shapes and lines; further on, the formulas are accompanied by details about their colour, which allows for the creation of an image. ]]> 2016-09-23 10:41:19 UTC https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125962312 Size of Vectors radoslavx25 https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125962357 The size of vector graphics is small because the computer only stores the details of the objects which do not require a lot of memory.]]> 2016-09-23 10:41:31 UTC https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125962357 Can vectors be grouped? karan1999desai https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125962407 They can be grouped into objects which is why sometimes vectors graphics are sometimes called object orientated graphics.Individual vector objects can be edited independently, they can also be duplicated and re-sized with only a small increase in file size.]]> 2016-09-23 10:41:43 UTC https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125962407 Quality on enlargement or reduction of Vectors radoslavx25 https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125963341 When vectors are resized they do not lose quality]]> 2016-09-23 10:45:00 UTC https://padlet.com/karan1999desai/hmr1ooud6z2i/wish/125963341 CAD Is the example that you can use.
