Necessity of Image Compression
Digital images are very large in size and hence occupy larger storage space. Due to their larger size, they take larger bandwidth and more time for upload or download through the Internet. This makes it inconvenient for storage as well as file sharing. To combat with this problem, the images are compressed in size with special techniques. This compression not only helps in saving storage space but also enables easy sharing of files. Image compression applications reduce the size of an image file without causing major degradation to the quality of the image.
Image Compression Applications
Image compression applications make use of various techniques and algorithms in compressing images. The techniques thus used by image compression applications can be classified as lossless and lossy compression. The method of compression used depends on the desired quality of output. If the image compression application is expected to produce a very high quality output without any loss in fidelity, lossless compression technique is used. This technique is used where a high degree of accuracy is a must. In applications where some quality can be compromised, lossy compression technique is used. In lossy compression, there is minor loss of quality, but the loss is too little to be visible. This technique is used in applications where a little compromise on quality of image is acceptable.
Image Compression Applications for Increased Efficiency
Image compression applications make it easier to compress images. The compression tools are user friendly and can be used by anyone with minimal knowledge. The images are compressed just by selecting the images and setting the options. One even gets to choose the algorithms for compressing images and hence have the control over the output image. Image compression applications compress images quickly. Thus they result in efficient utilization of time, memory and bandwidth.
