Adding a table of contents to a long PDF makes it easier to navigate. Here is how to create and insert one using free browser tools.
Go to pdfeditor.onl/page-numbers. Add page numbers to the document. Note the exact page numbers of each major section heading.
Open a text editor (Notepad, TextEdit) and draft your table of contents: Section 1 — Introduction ......... 1, Section 2 — Methodology ......... 5, etc. Copy the text.
Go to pdfeditor.onl/organize-pdf. Insert a blank page at the beginning. Download. Open the PDF in pdfeditor.onl/pdf-studio. Use the Text tool to type or paste the TOC content on the blank first page.
Tip: For a professional appearance, match the TOC font and size to the document body text. Use leader dots (....) to connect section titles to page numbers.
Clickable PDF bookmarks and hyperlinks require Adobe Acrobat Pro or LibreOffice. The method above creates a visual TOC page only.
