Four Best Free Image Compressor – 2023 Guide

Nowadays, more and more people tend to share their life photos on the Internet social media. You can see many cute pets and family unions and travel journeys on Instagram and TikTok. However, I believe that you must have the same experience when you are about to share an image, but the platform notices that your image size might be too big for the platform requirement. I know basically, no one will concentrate on reading those rules of platforms. Like Instagram, it is directly written in the guidepost. But normal in the case that people can only notice the limited uploading image size after they have been warned. But it isn’t fair just because of these rules, people have to give up putting their heart and soul into somewhere they want to share. Therefore, the need to find a free image compressor comes with it.

For this reason, after thoroughly selecting and comparison of the products on the Internet, I am here to introduce to you the Four Best Image Compressor for this year. Every tool has its features and shortcomings. There are two desktop software and two online methods. But among all, WorkinTool File Compressor is the one I personally recommend the most.
