TinyPNG online image compression is a tool, a smart lossless compression technique is adopted to reduce PNG image size, and this method can reduce the amount of color images through, to reduce the space required for the stored images, this approach can significantly reduce the size of the picture, but it won’t cause too much damage images, pixel lower, and so on, It is indistinguishable, at least to the naked eye, and preserves PNG’s alpha transparency.

Like TinyPNG, Optimizilla can batch compress up to 20 JPG or PNG images at a time, and then pack them for download. Optimizilla uses optimal optimization and compression algorithms to achieve the smallest JPEG and PNG images while maintaining the best quality to size ratio.

There is no limit on the number of users and the size of pictures. It is completely free. One of the interesting things I found was that the compression of the image actually increased the size of the image, let’s say to optimize the image quality. There is no limit on the number at a time, which is an advantage.
