A-PDF Image Downsample provides a quick way to resample the image in Acrobat PDF documents directly. It reduces the size of PDF files by reducing the resolution of those images to match specific quality requirements and by compressing the images. Then it makes PDF files to read faster on web. It supports both lossy and loss-less compression. Many factors affect file size and file quality, but when you are working with image-intensive files, resample and compression are important. A-PDF Image Downsample's other features include processing a batch of PDF file, even working with password protected files; filtering small images which may be a logo or else; and dealing out some page only to speed the processing. A-PDF Image Downsample does NOT require Adobe Acrobat, and produces documents compatible with Adobe Acrobat Reader Version 5 and above.
