That depends on the compression method used. There are some compression methods that are lossless, meaning that the original data can be 100% reconstructed. Zip files and similar methods use lossless compression.
The compression used for images, photos, and video files is typically not lossless. Depending on the degree of compression achieved, there will be artifacts (imperfections) introduced in the data. A balance must be struck between the resulting file size and the degradation of the data.

What software can test the quality of a file compression?
There are many pieces of software that can test the quality of a file compression software. The file compression software itself can give a percentage of compression, as well as a verification of whether it is compressed properly. One can also check the 'checksum' of the file.
How does file compression affect TXT?
Cool
What does compression do to video files?
It lowers file size and decreases quality.
How often should one use file compression programs to compress all their files?
This all depends on your personal preferences. Compressing files will make them easier to transfer and transport. However, compressing files will also affect the quality. If it is an image or video, compressing it will greatly affect the quality.
How does the quality of a sound or image file relate to its file size?
Smaller the size, more information is lost due to compression and therefore the quality gets lost. Smart compression techniques like mp3 or jpeg are using assumptions about the intended use of the image/sound to minimize compression losses in the relevant domain.
Does A file compression utility is a program that removes redundancies in a file to reduce the file size?
File Compression
How does file format affect image quality?
By reducing the size if a image
How resolution and colour depth affect file size and image quality?
Changing the image resolution will affect the file size of the image and the quality of the image. Image resolution is measure in DPI, which is Dots Per Inch, this means that if you increase the resolution then the DPI will increase and the quality of the image will get better as a result as there are more pixels that make up the image, so the image will be more distinct and sharper. When the image resolution is increased the image has more pixels, this is the exact opposite to the compression techniques, this means that the file will get a lot bigger as the number of pixels increases. Decreasing the resolution, however, will make the image quality lower but will reduce the file size.
Which utility is not a systems tool utility?
I think answer is File Compression
Can low compression affect timing?
No. Low compression does not effect timing but timing can affect compression.
Difference between lossless and lossy compression?
File compression uses software algorithms to reduce file size by reducing the bit-rate of a file. Lossy compression takes it a bit further and lowers the quality of thr file to make it even smaller. Lossy compression is commonly used for media files, but would not be appropriate for other types of files.
How large can a 2.37MB JPEG file be enlarged?
There is no upper limit when enlarging an image. The limiting factor is the quality loss. When enlarging you will always loose quality. Note: the filesize for a JPEG does not tell much about it since JPEG uses a lossy compression algorithm - i.e. the resulting file size is depending a lot on the original image and the compression level.
