Data compression method

Text compression techniques
In lossy compression, the data in a file is removed and not restored to its original form after decompression.
Specifically, data is permanently removed, which is why this method is also known as irreversible compression.
This data loss is not usually noticeable..
What is compression method?
In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation.
Any particular compression is either lossy or lossless.
Lossless compression reduces bits by identifying and eliminating statistical redundancy..
