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: -Lossy compression is typically used when a file can afford to lose some data, and/or if storage space needs to be drastically ‘freed up’. Here, an algorithm scans image files and reduces their size by discarding information considered less important or undetectable to the human eye.
Detailed explanation-2: -Lossy compression reduces a file by permanently eliminating certain information, especially redundant information. When the file is uncompressed, some of the original information is not there, although the user may not notice it.
Detailed explanation-3: -Lossy compression reduces an image file size by permanently removing less critical information, particularly redundant data. Lossy compression can significantly reduce file size, but it can also reduce image quality to the point of distortion, especially if the image is overly compressed.
Detailed explanation-4: -Lossy compression means that the image size is reduced while some data from the original image file is eliminated. If you’re asking if lossy compression is reversible, the answer is: no. The lossy image process is irreversible. Once you have compressed an image this way, you can’t go back.
