PURPOSE How to add and manage bookmarks in PDF documents. GENERAL STEPS Open the PDF in Adobe Acrobat and use the appropriate tool, such as Prepare Form, Fill & Sign, Organize Pages, Optimize PDF, Protect, or Bookmarks. VERIFY RESULTS Review the final PDF for page order, form fields, signatures, bookmarks, file size, permissions, and readability before sharing. TROUBLESHOOTING If Acrobat behaves unexpectedly, save a copy of the PDF, restart Acrobat, confirm the file is not read-only, and test with another PDF if needed. BEST PRACTICE Keep an original copy before editing PDFs. Acrobat changes can be powerful, which is great until the wrong page disappears into the void.
