- JPEG.
Compression Drawbacks :
Unable To Read :
- Compressed files are unable to read and understand by human's.
Less Quality :
- Compressed media files are having less Quality when compared to the original files.
Processor Consumes More Time :
- Processor consumes for doing compression and it takes more time to decompress and work on it.So,speed of processor will decreased.

Faster transmission over a network.So reduce the transmission cost. | If you want to compress and decompress you must need to buy the software.So,you need to put more money. |
It will take less storage space .So, no need to buy additional memory devices. | But,while computer compressing and decompressing the file computer will use more memory. |
Compressing a file will is more easy. | When we compress the file.if you want to read the compressed file you must need same decompression technique to decompress the file. |
We will provide privacy to the compressed file by putting the Password while compressing. | If you forget the password unable to decompress the file. |
compressed file will take the less time for transfering and downloading over network. | while decompressing and reading a compressed file computer will take more time. |
Lossless compression technique will provide good quality after decompressing also. | Lossy compression will provide the less quality of data even after decompressing also. |
