How to Compress WordPress Images in Bulk for FREE (in Few Secs)

Compressing images is a crucial step in optimizing your website’s performance. It reduces the size of your image files, which in turn decreases the page load time and improves the overall user experience. However, compressing images one by one can be a time-consuming task, especially if you have a large number of images on your WordPress site. That’s where comes in handy.

I recently came across, a free online tool that allows you to compress multiple images at once. With this tool, you can easily reduce the size of your images without compromising on quality.

The best part is that it’s completely free to use, and you don’t need to download any software or plugins to get started.
