There are many pdf tools, but this is one of the most full-featured and robust I have used. It has also been actively maintained for many years.

A sample list of features:

• Merge PDF files together, or split them apart
• Encrypt and decrypt
• Scale, crop and rotate pages
• Read and set document info and metadata
• Copy, add or remove bookmarks
• Read, write and modify annotations
• Put multiple pages on one (imposition)
• Stamp logos, text, dates, page numbers
• Add or remove attachments
• Losslessly compress PDF files
• Convert PDF files to and from JSON
• Draw shapes and text on PDF files
