Best image compressor in 2021, lossless image compression.
The logic behind Image compression
Before heading towards compressing the images, you should know the hidden logic behind image compression. Image compression can be of broadly two types, (lossless) in one case you can compress images without losing quality, (lossy) but in another, there will be a less amount of difference without losing the quality.
Most people try to compress images with a huge decrease in the quality, in this case, they are actually cutting some of the parts or details of the images and this cannot be said as a compression. Image compression involves, changing the format of the image with some other formats which can reduce the size of that image.
Let me very clear, the image compression topic is very vast and is very tricky also, it involves various techniques and methods for image compression. Here I will not explain this topic very deeply, but I will give you a rough idea about image compression.
As you people know that the compression is mainly categorized into two forms- Lossless image compression and lossy compression, here lossless compression techniques are adopted for written documents since a little loss in the data can be a huge headache, while lossy image compression techniques are adopted in videos, photos, and songs, since a little bit lost in the quality cannot have a bigger impact.
You can compress your image in two forms- one by reducing its dimensions and by removing some parts and details of the image or either you can convert your image in some other file formats such as textual format to save size. For example, when you want to compress your image with Winrar and WinZip, then, in this case, you are converting your image into some other file formats and when you again want your image then you have to decompress it, to view it in the form of an image. Have you ever thought- How this happens, just take an example, can I write “3x3x3x3x3x3x3x3x3” in short form, the answer is yes, we can write as 39 since this will consume less space. So these types of techniques are also adopted in image compression since images are combinations of pixels, a large number of pixels are added to make an image, so the row and column number of the required pixels along with their color code can be stored in textual form, this will absolutely save some space.
While in another case you can easily delete some parts of an image or you can lower the quality of your image to reduce its size, such that, a little bit change in the quality cannot have any kind of impact on the image visibility but can have its effect on the size of the image itself.
So in this article, I will be showing you the lossy technique of image compression.

Best software for image compression in 2020 and 2021
So in this article, I will be showing you very effective image compression software, which can compress your image without having an impact on your image, but can reduce the file size of the image by more than 70%, if you have an image of 2 MB then you can compress your image up to 580 KB by using this software, the name of this software is “Advanced JPEG compressor”. (downloading link have been given below)
This software gives you tons of features and is equipped with useful features for controlling the size and quality of your image.
How to compress images, step by step guide
Step- 1} First of all download and install Advanced jpeg image compressor, and open it…
Step- 2} Now click on the file and then click on open, and then you will see two separate boxes in the viewing window, on the left side you will have your original image, and while on the right side you will be having your compressed image.
When you will have your required image opened you will be having a set of settings by which you can control the size and quality of your image.
Such as in the lower menu, you will be getting the options for controlling the size and quality of your image…
Here you can set the compression level to reduce the size of your image, the best settings Are to have an upper compression level up to 51% and a lower compression level up to 60%. If you want to decrease the size of the image more than just decrease the levels of detail quality equalizer. You can also rotate your image and can also apply a watermark on your image.
After having all the settings according to your need just see the compressed image size, one thing you should know that the more you decrease the size of the image, the quality of the image also decreases.
Step- 3} now after you are done with settings you can click on apply settings on the upper menu as shown in the figure.
Now after applying the settings just click on the file and then save as. Now just see the difference between quality and size. In quality, there will be less difference while in size there will be a huge difference of more than 70%.
Here in this software, you will get many more features, which you can learn by using this software. This software also provides you the feature of batch image processing, by which you can compress multiple images at once. Just have look at these features also….
By using these features you can crop your image and can do- removing red-eye, applying greyscale, colors, etc. You can see the difference between file sizes of the image which I have compressed…
2.46 MB image has been converted to 803 KB. You can also set the image size for target values by using this software, if you want an image of 100 KB then just set the file size and the software will do the automatic correction.
So now I think you have understood the basics of image compression and if you liked this article then just stay tuned for more, thanks for reading this article.
