Why Page Numbers Matter

Page numbers turn a loose stack of pages into a navigable document. Reviewers can point to page twelve instead of saying somewhere in the middle, and printed copies can be reassembled correctly if dropped. Thesis committees, courts, and corporate clients often require numbering before they accept a submission. Automatic numbering in the browser is far faster and neater than typing numbers manually into a scanned file.

Step-by-Step: Number PDF Pages

Add consistent footers across the whole file in a few clicks.

1. Open the numbering tool: Launch the Add Page Numbers tool on KPM from your laptop or phone browser.
2. Select your PDF: Load the final version of the document. Finish all edits and merges first, because adding pages later will shift existing numbers.
3. Choose position: Pick bottom center for formal reports or bottom right for business documents. Centered numbers work best for double-sided printing.
4. Pick a format: Use simple numbers like 1, 2, 3 for most work, or Page 1 of 20 when readers need progress context.
5. Set margins: Keep numbers clear of body text and tables. Increase bottom margin slightly if footers overlap with existing content or stamps.
6. Apply and review: Generate the numbered file, scroll from first to last page, and confirm the sequence starts at one and has no duplicates or gaps.

Tips for Clean Numbering

• Exclude covers thoughtfully: If your cover should not show a number, start numbering from the second page while preserving logical order.
• Use readable size: Nine to eleven point gray text looks professional without distracting from the main content.
• Check scanned margins: Scans with dark edges may need extra padding so numbers do not blend into shadows.
• Keep a master copy: Save the unnumbered original in case you later insert annexures or reorder chapters.

Privacy Note

Numbering is done locally in your browser with no uploads. Theses, legal bundles, and internal audits remain private on your device while you prepare them for submission.
