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?
This is the best image compressor. Not only it does a great job (many can as well), but it is almost the only one that doesn't need to load up all the photos, and have a file manager to look for folder that needs photos to be compressed. This is absolutely needed for me as I have tons of work photos. Great job!
