Image compression software refers to computer programs that reduce the file sizes of images. This reduction usually can be achieved with minimal loss of the data contained within the file. Generally, when image files are compressed, the redundant parts of images are sacrificed so that the image size can be reduced. Users typically look into compressing images because of their storage needs.
Creating smaller image files and making images compact for storage is an integral part of handling digital data. Both of these activities can result in smaller file sizes. After image compression has been achieved, the data necessary to show and store an image has been significantly reduced, freeing up space for storing other files.
Image compression software can have numerous practical applications. Those who run Websites and online businesses might consider image compression software to be a tool necessary to their trade, because images often are a big part of selling products or services. The software might also be used by students or others involved in academia for projects, presentations or reference materials. In addition, the average user might find image compression software handy when trying to store and organize files.
This type of software usually can be bought at a retail store, but it also can be found as freeware on the Internet. The specific program that a user decides to install on his computer will depend largely on his goals and the types of software features that appeal to him. For example, some image compression software can handle compressing multiple images at once, but others might compress only one image at a time. Image compression software might also be bundled with options that allow a user to edit, organize, rename, add effects and share images. While some compressors will be able to work with standard file formats such as JPEG, PNG, GIF and TIFF, some compressors might be able to compress other data types, such as text.
While image compression software can be downloaded and installed on a user's computer, it should be noted that image compression also can be completed online. Some companies offer image compression service on their Websites. Single images can be compressed simply by uploading the image onto the Website and clicking a button that so that the image will be compressed. Depending on the Website, users might also be able to decide if they want to compress the file by percentage, pixel or degree. Previewing also might be available to users so that they are able to see exactly what they are about to save and download onto their computers.
