What are the three most common causes of compression loss

[strawberry]

I'm having trouble understanding compression loss and what might be causing it. Can anyone help me out and explain the three most common causes of compression loss? I'm sure I'm not alone in this and would appreciate any advice or experiences anyone else has had! Thanks in advance.

1. Data Corruption
Data corruption is one of the most common causes of compression loss. This occurs when the data is accidentally or maliciously modified or deleted, causing the entire file to become corrupted. This can happen due to hardware or software errors, viruses, or user error.

2. Incomplete Compression
Incomplete compression is another common cause of compression loss. This occurs when the original data is not compressed completely, leaving some of the data uncompressed. This can occur due to incorrect settings or the use of a low-quality compression algorithm.

3. Incorrect File Format
Incorrect file format is the third most common cause of compression loss. This occurs when the file is saved in the wrong format, resulting in data loss. This can happen due to user error or an incorrect file extension.
