Compression in digital files refers to the process of encoding data with fewer bits than the original file. To put it simply, it refers to the process of reducing the size of a huge file.
Compression comes in two flavors: lossless and lossy. When a compression program eliminates redundant, empty, or unnecessary parts from the source file, it is said to be doing lossless compression. Consequently, the original file is reduced in size without sacrificing quality. It is known as lossy compression when the compressor eliminates unnecessary or superfluous portions from the source file. As a result, the file gets smaller but loses quality. Depending on how much quality loss you can tolerate, you may choose how tiny you want the final file to be when using lossy compression.
The size of the file might vary greatly depending on the image's source. For instance, a JPG taken with a high-end DSLR camera may contain several gigabytes. This could be too large for you, though. This image would benefit greatly from compression.
In a similar vein, your phone may contain huge photos. These pictures may be using a lot of hard disk space and stopping you from shooting additional pictures. This issue could be resolved by compressing them to make more internal storage available.
Regarding the security of our free service, there is no reason to be concerned. If you are not satisfied with your compressed files, you may simply try again without losing your original files on your machine. You don't have to worry about data security because our automated system deletes all data after an hour.
