Use This Best Image Compressor Online Free to Cut Image Size from MBs to KBs

Best image compressor

To be true, there is no dearth of ‘best’ image compressor online free for use. Just search for the term image compressor online, and you’re likely to find scores of results to choose from.

Does that make your job easier, especially when you’re short on time?

I guess not.

You cannot afford time and (a good deal of) effort to try each and every image compressor online in the search results.

Instead, what you need is time-tested guidance, and expert opinion on a really good image compressor online for your needs. And if that happens to be a free tool, all the better.

This is what I’m going to explain in this article.

Let me show you some images in pairs before and after compression using the tool I’m going to explain soon.

Take a close look at them and judge for yourself the quality of compression done by the image compressor online which I’ve used here and will show you shortly.

Before that, here is how (watch the animated illustration below) you can find out the image size in Firefox browser. There is no easy way to do this in Chrome.

Right-click on an image > Select View Image Info from dropdown > Find the image Size

Okay, let me now put up 7 pairs of PNG images below along with respective sizes before and after compression.

For all these images I’ve used the same image compressor online, which I’ll explain after the images.

Do you see any major change in the images before and after compression?

I think not.

Even if there are changes, they are not markedly discernible.

There is one point I need to mention here.

All these images are in PNG format, not JPEG. Usually, PNG images retain composition to a large extent when compressed, but JPEG images tend to pixelate soon.

Okay, let me now explain the online image compressor tool I’ve used, which I think is the best of its type at the present time.
