Why PDF Page Numbering Matters

In professional environments, page numbering is not just cosmetic:

• Court Filings & Legal Discovery: Legal filings often mandate consecutive page numbering (Bates numbering) so judges and attorneys can reference specific lines during proceedings.
• Academic Research & Theses: University guidelines require strict pagination styles (e.g., "Page 1 of 50" or bottom-right placement).
• Business Proposals & Audits: In multi-vendor bids, page numbering ensures reviewers can reference sections during contract negotiations.

Pro Tip: Excluding Cover Pages & Indexes

If your document has a decorative title cover or table of contents that should not display page numbers:

1. Use the Starting Page option to begin numbering from page 2 or page 3.
2. If you need to reorder sections before numbering, arrange them using the Rearrange PDF Tool.
3. If you need to merge multiple documents before adding a continuous numbering sequence across all files, combine them first using the Merge PDF Tool.
