How to Bookmark a PDF for Free: Mark Pages and Navigate Quickly

· 6 min read

Quick summary: To bookmark a PDF page on Mac, open it in Preview → go to the page you want to mark → View → Bookmarks → Add Bookmark. To bookmark in Apple Books on iPhone, open the PDF → tap the bookmark ribbon icon at the top right. Bookmarks let you jump back to any page instantly without scrolling.

PDF bookmarks fall into two categories: reading bookmarks (personal page markers you add while reading, stored per app) and structural bookmarks (the navigation outline embedded in the PDF file itself, visible in the sidebar of most PDF viewers). This guide covers both. You can also upload any PDF to our free AI PDF reader to navigate and search content without needing bookmarks.

Understanding PDF bookmarks

Reading bookmarks (app-level): Personal page markers you create while reading. These are stored by the app — removing the app removes the bookmarks. Preview bookmarks and Apple Books bookmarks work this way.

Structural bookmarks (PDF outline): A navigation tree embedded inside the PDF file — visible in the Bookmarks panel of most PDF viewers. These are part of the file itself and visible to anyone who opens the PDF. Academic papers, reports, and ebooks often have these built in.

How to bookmark a PDF in Preview (Mac)

Preview stores reading bookmarks per file and shows them in a sidebar panel:

  1. Open the PDF in Preview.
  2. Navigate to the page you want to bookmark.
  3. Go to View → Bookmarks → Add Bookmark (or press Cmd+D).
  4. A bookmark is added for the current page.

To view and jump to bookmarks:

  • Go to View → Bookmarks — a panel opens showing all bookmarked pages.
  • Click any bookmark to jump to that page.

To remove a bookmark:

  • Open View → Bookmarks → right-click the bookmark → Delete.

Note: Preview bookmarks are stored in macOS’s metadata for that file, not inside the PDF itself. If you move the file to another computer, bookmarks may not transfer.

How to bookmark a PDF in Apple Books (iPhone/Mac)

Apple Books provides proper reading bookmarks for PDFs:

iPhone:

  1. Open the PDF in Apple Books (tap Share → Books from Files or Safari).
  2. Navigate to the page you want to mark.
  3. Tap the bookmark ribbon icon in the top-right corner of the screen — it turns red/filled.
  4. To see all bookmarks: tap the Table of Contents icon (three lines) → Bookmarks tab.
  5. Tap any bookmark to jump to that page.

Mac:

  1. Open the PDF in Books.
  2. Navigate to the target page.
  3. Click Bookmarks → Add Bookmark in the menu bar, or click the ribbon icon in the toolbar.

How to view the structural bookmarks (PDF outline) in a PDF

If a PDF has a built-in navigation outline, all major viewers show it:

Preview (Mac): View → Table of Contents (or click the sidebar icon → Table of Contents tab).

Adobe Acrobat Reader (Windows/Mac): Click the Bookmarks panel icon in the left sidebar (bookmark ribbon icon). The outline tree appears — click any entry to jump there.

Chrome/Edge: Open the PDF in the browser → click the Table of Contents icon in the left panel (appears when you hover the left edge of the viewer).

Apple Books (iPhone): Tap the Table of Contents icon → the Bookmarks/Contents tab shows any embedded outline.

How to add structural bookmarks to a PDF (embedded in the file)

Free options for adding an embedded bookmark outline to an existing PDF are limited — most free tools only let you view existing bookmarks, not add new ones. Here are the options:

Option 1: Create from a source document (best quality)

If you have the original Word, Google Docs, or Pages document:

  1. Format headings using proper heading styles (Heading 1, Heading 2, etc.).
  2. Export to PDF — headings automatically become PDF structural bookmarks.

In Microsoft Word: File → Save As → PDF → Options → check “Create bookmarks using Headings.”

In Google Docs: File → Download → PDF — Google automatically converts headings to bookmarks.

In LibreOffice Writer: File → Export as PDF → check “Export bookmarks as PDF targets.”

Option 2: LibreOffice Draw (for existing PDFs)

  1. Open LibreOffice Draw.
  2. Open the PDF: File → Open → select the PDF.
  3. Draw opens each page as an editable drawing.
  4. File → Export as PDF → the General tab has a “Export bookmarks as PDF targets” option.
  5. LibreOffice creates bookmarks from any text frames it identifies as headings.

Results vary depending on the PDF’s structure — complex or scanned PDFs may not produce useful bookmarks.

Option 3: PDFtk (command line, free)

PDFtk can read and write the bookmark structure (called “bookmarks” in its data format):

# Dump existing bookmarks
pdftk input.pdf dump_data output metadata.txt

# Edit metadata.txt to add bookmark entries, then apply
pdftk input.pdf update_info metadata.txt output output.pdf

Bookmark entries in the metadata file follow this format:

BookmarkBegin
BookmarkTitle: Chapter 1
BookmarkLevel: 1
BookmarkPageNumber: 5

Install PDFtk: brew install pdftk-java (Mac) or download from the PDFtk website.

How to search a PDF instead of bookmarking

For long PDFs, searching is often faster than bookmarks:

  • Mac (Preview): Cmd+F → type a word — jumps to the first match.
  • iPhone (Apple Books): Tap the magnifier icon → type the search term.
  • Any browser: Ctrl+F or Cmd+F.

Frequently Asked Questions (FAQ)

Do PDF bookmarks survive when I share the file?

Reading bookmarks (Preview, Apple Books) do not — they are stored locally per app. Structural bookmarks embedded in the PDF file do survive sharing. Anyone who opens the PDF sees the same outline.

Can I add bookmarks to a scanned PDF?

Scanned PDFs are images — there is no text structure to bookmark. You can add reading bookmarks in Preview or Apple Books (they mark the page number, not the text). For structural bookmarks, run OCR first to create a text layer — see how to OCR a PDF for free — then generate bookmarks from headings.

Why don’t I see a Bookmarks panel in my PDF viewer?

The PDF has no embedded bookmark outline. Many PDFs — especially scanned documents, simple reports, or exported spreadsheets — have no structural bookmarks. Use the reading bookmarks in Preview or Apple Books to mark pages yourself.

Can Adobe Acrobat Reader (free) add structural bookmarks?

No — adding and editing structural bookmarks requires Adobe Acrobat Pro (paid). Acrobat Reader (free) can only view existing bookmarks. Use LibreOffice or the source document approach for free bookmark creation.

How do I jump between bookmarks quickly in Preview?

Go to View → Bookmarks — the panel lists all your bookmarks. Click any entry to jump instantly. You can also use View → Bookmarks → Next Bookmark / Previous Bookmark from the menu.
