HETWORKS

<p>You probably know that the speed of your website is important for both user experience and for your search engine ranking. The people<br />
at TinyPNG.com offered this great service where you could upload your PNG images and shortly also your JPG images, to have the file size<br />
shrinked to much lower amount of data, without a noticable reduce of image quality. And that is great! Compare your Google pagespeed score<br />
before and after you shrinked your images. You will gain many points.</p>
<p>The disadvantage of using TinyPNG is that you had to use the service upfront, before you could upload your images into your WordPress<br />
medialibrary you had to upload them to TinyPNG and download the shrinked files again. When the images were already in your medialibrary you<br />
had to do this all over, also for the images that were cropped by WordPress into the different filesizes. With this plugin that is all history.<br />
You just upload your images and as part of the proces these images are processed by TinyPNG.</p>
<p>This is what TinyPNG say themselves:<br />
How does it work? TinyPNG uses smart lossy compression techniques to reduce the file size of your PNG files. By selectively decreasing the<br />
number of colors in the image, fewer bytes are required to store the data. The effect is nearly invisible but it makes a very large<br />
difference in file size!</p>
