About Compress PDF Tool
Reduce PDF file size with a selectable quality trade-off or an optional target size. Stronger levels rebuild pages as compressed images, which can reduce sharpness and remove selectable text, links, forms, and annotations. Exact size reduction depends on the document and is not guaranteed.
