Which algorithm is used as compression technique?

Lempel–Ziv–Welch (LZW) is a lossless compression algorithm developed in 1984. It is used in the GIF format, introduced in 1987. DEFLATE, a lossless compression algorithm specified in 1996, is used in the Portable Network Graphics (PNG) format.

What is the best compression algorithm?

The fastest algorithm, lz4, results in lower compression ratios; xz, which has the highest compression ratio, suffers from a slow compression speed. However, Zstandard, at the default setting, shows substantial improvements in both compression speed and decompression speed, while compressing at the same ratio as zlib.

What are the 2 methods of compression?

There are two types of compression: lossless and lossy.

How many compression algorithms are there?

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