PRACTICAL GUIDE
What to know before you add pdf page numbers
Add page numbers places a small numeric label near the bottom of every page and saves a new PDF. Numbering may start at zero or any positive integer, with left, center and right positions.
Printed packets
Add a continuous reference so readers can discuss a finished document by page.
Report appendices
Start above 1 when the PDF continues from an earlier document.
Internal review
Add page references before a team exchanges comments.
HOW THE PDF CHANGES
Technical limits to understand
Standard font
The current version uses standard Helvetica with a fixed size and color. Prefixes, suffixes and custom fonts are not supported yet.
Bottom margin
Numbers are drawn over page content. Documents with text near the bottom edge may overlap and should be inspected.
No automatic TOC update
Added labels do not update bookmarks, tables of contents or numbers already printed on pages.
TROUBLESHOOTING
