Managing Your Workflow Beyond Annotation
Annotation is often just one step in your document management workflow. Once you have finished marking up your file, you may need to reorganize your pages using our rearrange tool, or perhaps merge several documents into one cohesive report. If you are dealing with large files, use our compress tool to make them easier to share via email.
