PDF Page Labels
Control what readers show as the page number: label pages 1, 2, 3 or i, ii, iii or A, B, C, with an optional prefix like "App. " — the front-matter numbering books and reports need.
About this tool
Readers number pages by label, not by file order — which is why a book's preface can be page iii while its first chapter is page 1. This tool writes those labels: decimal, roman or letter styles, an optional prefix such as "App. ", and a starting number of your choice.
Nothing is printed on the pages; labels are the metadata shown in reader toolbars, thumbnails and print dialogs, and every mainstream reader honours them.

Frequently asked questions
Labels vs printed page numbers?
Labels are metadata: the number the reader shows in its toolbar and print dialog ("Page i of 24"). They do not draw anything on the page — use PDF Page Numbers to stamp visible numbers.
Why do front matter pages use roman numerals?
Books and reports number prefaces in lowercase roman (i, ii, iii) so the main text can start at 1. Set the style here for the front-matter file, then merge.
Do all readers honour labels?
Yes — page labels are part of the PDF standard and every mainstream reader (Acrobat, Preview, browsers) displays them.
Are encrypted PDFs supported?
No. Encrypted or password-protected PDFs are rejected. Export an unlocked copy first.
