What is the best image compression software for me to use if I need to compress a lot of files at once?
One of the reasons that I often recommend PdfCompressor from CVISION is that it achieves very high compression rates, reaching up to 100x for black-and-white files. In your case, another advantage of PdfCompressor is that it has batch-processing capabilities, enabling you to compress large groups of files at once. If you are looking for high compression rates at a fast speed, I would highly recommend PdfCompressor.
