What is lossless compression?
lossless compression is a compression technique that will not lose any data in the process of compression.
lossless compression "packs data" into a smaller file size using the type of internal shortcut to indicate redundant data. If the original file is 1.5 MB (megabytes), the lossless compression may reduce it to approximately half of this size, depending on the type of compressed file. As a result, lossless compression is convenient for file transfer over the Internet, because smaller files are transmitted faster. Loss loss of compression is also useful for file storage because they occupy less space.
ZIP conventions used in programs like Winzip use lossless compression. For this reason, ZIP software is popular for compressing program and data files. This is because when these files are decompressed, all bytes must be present in order to ensure their integrity. If the program is missing bytes, it will not be launched. If the data file is missing bytes, t will be tof incomplete and garbled. Use GIF Also files to use lossless compression.
loss loss of compression has advantages and disadvantages. The advantage is that the compressed set decompresses the exact duplicate of the original ensemble and reflects its quality. The disadvantage is that the compression ratio is not so high, precisely because there are no data.
If you want to get a higher compression ratio - to reduce the file significantly above 50% - you must use loss of compression . Loss of compression delets a set of some of its redundant data. Because of this data loss, only certain applications are suitable for losing compression, such as graphics, sound and video. The loss of compression necessarily reduces the quality of the file to arrive at the resulting highly compressed size, but depending on the need, the loss may in some cases accept and even imperceptible.
JPEG uses loss compression, so convertGIF file on JPEG will reduce the size. It will also reduce quality to some extent.
lossless and loss of compression have become part of our daily vocabulary to a large extent due to the popularity of MP3 music files. The standard WAV sound file, converted to MP3 file, loses a lot of data because MP3 uses a loss -algorithm with a high compression that throws most of the data. This makes the resulting file much smaller to fit several dozen MP3 files, for example on a single compact disk, verse a handful of WAV files. However, the MP3 sound quality will be slightly lower than the original WAV, for some clearly.
As always, whether it compresses video, graphics or sound, it is ideal to balance the high quality of loss of loss -free compression. Choosing the right loss of the Convention is a matter of personal choice and good results strongly depend on the quality of the original file.
