Keep the original
Work on a copy and retain the source file. Removing encryption, changing permissions and verifying a digital signature are different tasks. Read each tool’s limits and processing location before selecting a sensitive document. Check important text, forms and links in the result; a readable copy is not automatically a valid signed original.
