How many compression algorithms are there?

There are two major categories of compression algorithms: lossy and lossless.

What is the best compression algorithm?

What is the overall best compression format? It depends on user's need, with compression ratio being only one factor of the equation. ZPAQ and ARC are the best compressors, but 7Z and RAR formats has a clear advantage in terms of decompression speed, faster than for any other tested format.

What are the 2 compression techniques?

Compression techniques fall into two classes: lossless and lossy. Both are very common in use: an example of lossless compression is ZIP archive files and an example of lossy compression is JPEG image files.
