When the image is decompressed and viewed, some data that was in the original photo will be missing. This form of compressions is sometimes referred to as вЂlossy compressionвЂ™ which is down to the fact that during compression some of the data from the image is lost permanently. The quality of the image has to drop a little depending on the amount of compression used, but if the right amount is applied, youвЂ™ll barely notice the difference. The whole process gets very technical, but the result is a smaller image size. First, it separates the image into sections of visual importance and then works out what parts of it can be removed without affecting the quality. JPEG compression uses DCT (Discrete Cosine Transform). ItвЂ™s not, as is commonly thought, an image format, but a compression method to reduce large file sizes. This is precisely what a JPEG file is merely a compressed version of the original file. Where would we be without compressed files? WeвЂ™d be waiting for a long time every time we wanted to send our photos via email or watching the spinning load wheel while we waited for them to upload to a sharing site or social media.Д¬ompression techniques allow an image file to be compressed to a fraction of their original size without resulting in a significant loss of quality.
