Owner password (optional)
Only needed to change the restrictions later. If you untick something and leave this empty, a random owner password is made and shown after saving. Use English letters, numbers and symbols.
Use this only on PDFs you own or are allowed to open. The PDF is re-saved with a PDF engine, so very complex interactive forms may be simplified. Protection uses 128-bit encryption that every PDF reader understands.
