9 best image optimization software for PC
Image optimization is essential for both professional and home use. This is especially important if you’re an online publisher or blogger. Most of the websites (focus on social networks) have limitations for image size. So, you have to optimize photos in order to use them online.
In addition, the large image files that you add from your gallery will increase website page size and thus, largely increase loading time. And we certainly don’t want that. Because the common visitor wants that page to load in a blink. On the other hand, we neither want to trade so much of the image quality for improving the site speed. So, compromising between size and quality is the only viable option.
In that manner, we’ve prepared some fast, online and offline tools for image compression and optimization. All of them are free to use.
