CompressImage is a free online bulk image compressor that you can use. Here it supports compressing JPG and PNG files and you just upload them on the website and then it will automatically optimize them. As soon as the website loads, it will start working on offline mode. It lets you choose output quality for the final compressed image.
This online image compressor is private as all the processing happens on your device. There are also no limits on how many images you can compress with it. In addition, it leaves a low carbon footprint as there are no servers involved, thus saving extra electricity. Just bookmark the web app and use it whenever you need it.
There are many online image optimizer tools that we have covered, but CompressImage offers the smallest image without the quality loss. However, this will not be the case for the image. When the image starts to pixelate, then you will have to increase the output image quality. But as compared to other tools, this is far better.
