Add PDF Page Numbers — what it does
Add page numbers to every page of a PDF, choosing the position, the starting number and the font size. Documents assembled from several sources arrive without numbering, and numbering is what lets a reader say "see page 14" and be understood.
When this tool helps
- Numbering a bundle assembled from several documents so it can be referenced.
- Adding numbers to a printed handout so a presenter and audience stay in sync.
- Numbering a submission where the recipient's guidelines require it.
How to use it
- Choose the PDF file.
- Pick the number position.
- Set the starting number and font size.
- Process and download the numbered PDF.
Accuracy, limits, and good practice
- Set a starting number other than one when the document follows on from another, so a multi-part bundle numbers continuously.
- Bottom centre is the safest position — it collides with existing content less often than the corners do.
- For numbering that shows the total as well, the header and footer tool produces "Page 3 of 12" instead of a bare number.
- Number after every other change to the document. Adding, deleting or reordering pages afterwards leaves numbers that no longer match their position.
Frequently asked questions
Can I skip numbering the cover page?
Split the cover off, number the rest, and merge it back — that gives a cover with no number and body pages numbered from one.
What if the pages already have numbers?
You will end up with two sets. Position the new numbers away from the existing ones, or work from an unnumbered source.
Does it renumber if I add pages later?
No, the numbers are drawn onto the pages. Adding pages afterwards means renumbering from the updated document.
Can I use roman numerals for a preface?
Not directly. Split the preface out, number it separately in your editor, and merge the sections back together.

PDF 加頁碼能做什麼
為 PDF 每一頁加上頁碼，位置、起始號碼與字級都可設定。由多份來源拼起來的文件通常沒有頁碼，而頁碼正是讓讀者說出「請看第 14 頁」時，對方能聽懂的基礎。
什麼時候用得上
- 為多份文件組成的卷宗編號，方便引用。
- 為列印講義加上頁碼，讓講者與聽眾同步。
- 為對方規定必須編號的送件文件加頁碼。
使用步驟
- 選擇 PDF 檔案。
- 選擇頁碼位置。
- 設定起始號碼與字級。
- 執行處理並下載已編號的 PDF。
精確度、限制與實務建議
- 文件若接續前一份，請把起始號碼設成非 1，多冊卷宗才能連續編號。
- 底部置中最安全——它與既有內容碰撞的機率比角落低。
- 若要同時顯示總頁數，頁眉頁尾工具可產生「第 3 頁，共 12 頁」，而不只是單一數字。
- 請在文件其他修改都完成後才加頁碼。事後增刪或重排頁面，會留下與位置對不上的號碼。
常見問題
封面可以不編號嗎？
先把封面拆出來，為其餘頁面編號後再合併，就能得到封面無頁碼、內文從 1 起算的結果。
頁面上本來就有頁碼怎麼辦？
會變成兩組。請把新頁碼放在遠離既有頁碼的位置，或改用沒有頁碼的來源檔。
之後加頁會自動重編嗎？
不會，頁碼是畫在頁面上的。事後加頁就得從更新後的文件重新編號。
前言可以用羅馬數字嗎？
無法直接產生。請把前言拆出，在編輯器中單獨編號，再把各部分合併回去。
