In this article, we will explain the ways to compress files in Windows and Mac to simplify your computer system’s disk drive. But before let’s grasp the understanding of File compression and why we need this.

What is File Compression and its various methods?

File compression is a process to decrease the file size to use less disk space. This process is used to send a file from a computer to another with a limited connection bandwidth. File compression is performed by the following methods:

Lossless Compression

This method uses data compression algorithms that enable the original data to be restored from the reduced data. Lossless file compression compresses a file without degrading its quality. Moreover, this compression uses Run Length Encoding (RLE), Huffman Coding and Lempel-Ziv-Welch (LZW) algorithms.

Lossy Compression

This method results in degrading data and quality from the original version of the file. This procedure is related to JPEG image format and audio files like MP3s or AAC files. Moreover, lossy compression uses fractal compression, Transform coding, DWT, RSSMS, and DCT.

Now, we will share the method to compress files in different Operating Systems.

What are the common image formats and best uses:


BITMAP (BMP) files are the image format that is used by Microsoft operating systems. We can’t use BMP for web purposes. These BMPs stores color data of each pixel image without compression. A bitmap is also called a raster graphic, which is a digital image formed by a matrix of dots.


Encapsulated PostScript (EPS) file formats are used in professional printing. This format is used in vector-based images including Adobe Photoshop, Adobe Illustrator and CorelDRAW. Additionally, this file is also compatible with PostScript printers which are used for transferring files between several graphic applications.


A GIF stands for Graphics Interchange Format, which is mainly used in web graphics. This format is used widely after JPEG. This image format uses lossless compression, which means it doesn’t noticeably degrade the original image.


JPEG stands for Joint Photographic Experts Group. This format used in digital cameras to store photos because it supports 224 or 16,777,216 colors.

Moreover, it uses lossy compression. This format may reduce the size of the bitmap (BMP) file format without any degradation in quality.


PNG stands for Portable Network Graphics. This file format is used for application graphics and also widely used on the Web.

This format supports an alpha channel and “RGBA” color space. There are three standard color channels (red, green and blue) with 256 levels of transparency.

Some other common file formats are PDF, PSD, TIFF, RAW and many more.
