Frequently Asked Questions

1. Will compressing and zipping a file reduce its quality?

If you zip a file, it will retain every bit of data that was initially present in it. Zipping does not reduce the quality of the image or video files present inside the archive. 

2. What is Lossy Compression?

Lossy compression is one of the two methods a file is compressed. It is sometimes referred to as an irreversible compression due to the fact that it doesn’t retain the original file after decompression, and this type of compression might compromise the data quality of the original file. 

Furthermore, Lossy compression algorithms remove data that is not noticeable to reduce the size of the file; it is mainly used in images, audio, and videos.

3. What is Lossless Compression?

Lossless compression does not hamper the data quality and is also known as reversible compression. After decompression, a file compressed using lossless compression can be restored to its original size. However, it does not compromise the data of the initial file. It just reduces the space the particular file takes on the hard disk.
