Compression

Compression reduces the size of files by encoding the data more efficiently. There are two main types: lossless compression, which preserves every bit of data, and lossy compression, which permanently removes some data to achieve smaller sizes.

Lossless compression reduces file size without losing any data, allowing the original file to be perfectly reconstructed.

Lossy compression reduces file size by permanently removing some data, achieving much smaller files at the cost of some quality.

Run-Length Encoding (RLE) is a simple lossless compression method that replaces consecutive repeated values with a count and a single value.
