This article gives you information on the top 27 image compressors that are able to compress the images without losing the quality. In addition to that, I will explain every image compressors in details, With that, I will also tell you the best 5 image compressors you can use Online and Offline.
But, before I go into the details of the individual image compressor, I would like to tell you a bit of information about Image Compressors and the Compression Type.
What is the Image Compressor?
In simple words, Image Compressor is the tool that reduces the size of the supported image without touching its quality. Here, I have come across the 41 image compressors, But I found only 27 that are affordable and useful.
As per the fact, Image compressors use an algorithm to compress the image. However, It must be noted that Every tool uses a different algorithm. Despite different algorithms, The type is remaining the same. Furthermore, I will explain the types later in this article.
And, This algorithm difference, Make these 27 image compressors unique to each other in terms of Quality and Speed.
Type of Compression Methods
There are two most common compression methods are used by Image Compressors.
- Lossy Compression
- Lossless Compression
Lossless Compression
It is used to compress the image without touching the quality. And, The supported images-type in this type are as follows.
- RAW
- PNG
- BMP
Lossy Compression
It is used to compress the image to a smaller size than it is in the Lossless compression, Hence, In order to that, Some parts of the image subjected to discard. But, It doesn't let the image look bad. The supported images-type in this type are as follows.
- JPG/JPEG
- GIF
Now, We will dive into the different Image compressors. See next to the table which contains the name of 27 different affordable and useful tools.
27 Tools to compress the images
The following table contains the names of the 27 different tools. It contains the name only.

Now, I am going to explain in brief about every tool. And, Note the image compressors that I am going to explain are following a certain order.
These tools are sorted by (Low File Size and High Quality) to (High File Size and Low Quality). Hence, I think the first one is better and the last one is the most ignorable.
Here, In this article, I've used only JPEG and PNG image formats.
