Removes data to reduce the file size. When the file is uncompressed, only a part of the original information is still there (There will be some loss of quality). Examples:mp3 and jpeg.
|
|
|
As the file size is compressed, the quality remains the same-it does not get worse. Also, the file can be decompressed to its original quality. Examples:GIF and FLAC. File sizes are larger than lossy.

None of the above

Detailed explanation-1: -Lossless compression restores and rebuilds file data in its original form after the file is decompressed. For example, when a picture’s file size is compressed, its quality remains the same. The file can be decompressed to its original quality without any loss of data.
Detailed explanation-2: -Lossless compression uses an algorithm to shrink the image without losing any important data. Essentially, it rewrites the file to make it more efficient-resulting in a smaller storage or transfer size. One way the algorithm does this is by replacing non-essential information and storing them in an index file.
Detailed explanation-3: -Lossless compression can reduce file sizes by removing and isolating redundant data. This method can make files smaller without affecting their overall quality. It is also completely reversible.
Detailed explanation-4: -Lossless advantages and disadvantages Advantages: No loss of quality, slight decreases in image file sizes. Disadvantages: Larger files than if you were to use lossy compression.
