Nitro PDF Professional includes a powerful set of tools for removing unwanted document objects and compressing images - helping you shrink files significantly.
Document objects. These general settings allow you to remove individual types of objects, including annotations, form fields, JavaScript, links, bookmarks, attachments, named destinations, embedded thumbnails, invalid or unused links, and bookmarks and name destinations.
Image compression. These image compression feature gives you a simple slider tool to apply more or less compression. The higher the percentage, the higher the compression.
