Just what I was looking for

Mass Image Compressor quickly reduces the image size in bulk. Optimizes PNG, PNG as well as WebP images. Entire folder with 100s of images was compressed with impressive speed - sub 1 minute. Works with animated images which is great for web developers.

Worth it!

As a semi-pro user for graphic compression, this is a life saver for speed and accuracy. I paid for life time version b/c I use this regularly. Well worth it if you need to do batches of 60MP raw to jpg compression.

Developer Response ,

Thanks for your support and for choosing the lifetime version! Glad to hear it’s helping with high-resolution batch processing. Let us know if you ever have feedback or need assistance.
