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 are the areas of compression?
The areas of compression are lossless compression and lossy compression. Lossless compression reduces the file size without sacrificing any data quality, while lossy compression reduces the file size by discarding some data, which may lead to a decrease in quality.
What does compression do to video files?
It lowers file size and decreases quality.
What two factors affect the size of a picture file?
The two main factors that affect the size of a picture file are resolution and image compression. Higher resolution images with more pixels will result in larger file sizes, while compressing the image can reduce the file size without compromising too much on 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.
What are the disadvantages of file compression?
Some disadvantages of file compression include potential loss of quality in the compressed file, longer processing time required for compression and decompression, and the need for specialized software to compress and decompress files. Additionally, some compressed file formats may not be widely supported, leading to compatibility issues.
What can compression cause?
Compression can cause loss of data or information, reduced quality of the compressed file, and potential compatibility issues with certain devices or software. It can also make it harder to edit or modify the compressed file.
Does A file compression utility is a program that removes redundancies in a file to reduce the file size?
File Compression
What are compression settings?
Compression settings refer to the parameters and options used to reduce the size of a file or data through compression algorithms. These settings can include factors like the level of compression, the type of algorithm used, and any additional options such as preserving metadata or specifying compression speed. Adjusting compression settings can impact the resulting file size, quality, and processing speed.
What is resizing and compression?
Resizing refers to changing the dimensions or resolution of an image or file, making it larger or smaller. Compression is the process of reducing the file size of an image or file by reducing redundant data, making it easier to store and share while minimizing loss of quality.
