Bulk Image Compressor helps you reduce over 80-90% of your image size with negligible quality loss. To show you just how efficient the compression is, we took a set of a little over 1700 images that was 16.88 GB in size. After compressing the images using this app, the total size came to just 317.3 MB. Amazing, isn't it?
Helped a lot. Size of the image folder was 1.7 GB around. It just made 247 MB. Wow I love this.
