Merge Google Docs into PDF with Bookmarks

PDF bookmarks are entries stored in the document's outline structure. A PDF viewer like Adobe Acrobat, Preview on Mac, or Chrome's built-in viewer shows these bookmarks in a sidebar panel. Clicking a bookmark jumps directly to that page. For a merged PDF of ten documents, bookmarks give readers instant access to any section.

The extension can generate two types of bookmarks: top-level bookmarks for each source document, using the filename as the bookmark name, and nested bookmarks from headings within each document. Documents that use Google Docs Heading 1 and Heading 2 styles contribute their headings to the bookmark outline automatically.

Apply Heading 1 and Heading 2 styles to the major sections of each source document before merging. These headings become bookmark entries nested under the document-level bookmark. A reader in the final merged PDF can expand any source document's entry and jump directly to any section within it.

By default, the bookmark for each source document takes the filename. If your files have descriptive names like 'Executive Summary', 'Financial Projections', and 'Appendix A', the bookmark names will be clear and useful. If files are named generically, rename them in Drive before merging so the bookmark names are informative.

Long legal documents with multiple exhibits need bookmarks so counsel can jump to a specific exhibit. Annual reports with a summary, data section, and appendices need bookmarks for board members reviewing specific sections. Training manuals with multiple modules need bookmarks for learners who return to reference specific content. Any document over 20 pages that spans multiple sections benefits from bookmarks.
