Add Bookmarks to PDF — Create Clickable Table of Contents

What Are PDF Bookmarks?

PDF bookmarks are the clickable entries in the left sidebar panel of a PDF viewer. They act as a table of contents — click a bookmark and the viewer jumps directly to that page or section.

Long documents without bookmarks force readers to scroll through dozens or hundreds of pages. Bookmarks solve this instantly.

When You Need Bookmarks

• Reports and whitepapers — readers jump to the section they care about
• Manuals and documentation — quick navigation between chapters
• Legal contracts — lawyers navigate to specific clauses
• Academic papers — readers skip to methodology, results, or references
• Merged PDFs — after merging multiple PDFs, bookmarks mark where each document starts

How to Add Bookmarks Online

Step 1: Upload Your PDF

Open MyPDF's Add Bookmarks tool and upload your document.

Step 2: Define Bookmark Structure

Add bookmarks by specifying:

• Title — the text shown in the bookmark panel (e.g., "Chapter 1: Introduction")


• Page number — which page the bookmark jumps to


• Nesting level — create sub-bookmarks under parent bookmarks

Step 3: Download

Click "Add Bookmarks" and download your navigable PDF.

Bookmark Best Practices

1. Mirror your document's heading structure — if the document has chapters and sections, create a matching bookmark hierarchy
2. Keep titles concise — "Q3 Financial Results" not "The Complete Financial Results for the Third Quarter of 2026"
3. Include page numbers in long documents — helps readers orient themselves
4. Add bookmarks after merging — when you merge PDFs, the original bookmarks may be lost

Bookmarks vs Table of Contents

Feature	Bookmarks	In-Document TOC
Location	PDF viewer sidebar	First pages of the document
Always visible	Yes (toggle sidebar)	Only when scrolled to TOC page
Clickable	Yes	Only if created with hyperlinks
Prints	No	Yes
Best for	Digital reading	Both digital and print

Ideally, use both — a printed TOC on page 1-2 plus bookmarks in the sidebar for digital readers.
