A compression algorithm that doesn't affect the original data. In other words, the uncompressed file will be exactly the same as the file before compression, bit for bit. Common lossless file types include:

• Lossless Compression

• lossy Compression

• File Compression

• Data Compression

A compression algorithm that slightly alters the data to make it easier to store. Lossy compression takes advantage of the limitations of human sight and hearing, and is usually used for images, videos, and audio files. Common lossy file types include:

• Data Compression

• File Compression

• Image Compression

• Lossy Compression
