After years of using the JPEG & PNG Stripper to remove the metadata from my images before publishing on the web, I’ve recently discovered an even better tool.
It’s called PNG Gauntlet and performs LOSSLESS compression on JPEG, PNG, GIF, TIFF and BMP files.
It analyses an image file, strips any redundant information and metadata then applies multiple compression methods until the best result is found.
In my experience, it can even reduce the file size of images that the JPEG & PNG Stripper has previously processed.
