20 Best Image Compression Tools In 2024: Comprehensive Guide

Why is it critical to find the best image compression tool? Simply, image compression or resizing reduces an image’s file size while retaining its quality to take up less space on web hosts. According to the most recent data, 1.81 trillion photos will be taken in 2024.

Meaning and Importance of Image Compression

Image compression is a method of reducing or compressing an image’s data to cut down the value of transmission and storage size. When you compress a digital image, it maintains the same quality yet shrinks the amount of data so that more images are stored in a given amount of memory space. 

‍

There are two primary types of image compression:

‍

1. Lossless Compression - It is a method to reduce the size of an image file while maintaining the same quality as before being compressed. Performing a lossless compression on your image means getting a smaller file size without reducing its quality.

‍

2. Lossy - This compression type reduces an image’s file size by permanently removing inessential data. So, it can significantly reduce file size and image quality.

‍

Here are the major benefits of image compression:

• Faster-loading website pages.

• Increase retention rate.

• Conserving more storage space.

• Improved user-experience.

• Better SEO rankings, etc.
