新增頁首與頁尾
在每一頁的頂部和（或）底部蓋上自訂文字。
運作方式
上傳您的 PDF，輸入頁首和（或）頁尾文字，然後下載結果。一切都在您的瀏覽器中完成——開啟文字欄位下方顯示的頁碼預留位置，即可在每一頁自動填入頁碼。
我可以在頁首或頁尾文字中加入頁碼嗎？
可以——文字欄位支援目前頁碼與總頁數的預留位置（請參考欄位下方的提示）。輸入後會在每一頁自動取代成對應數字，例如「第 1 頁，共 12 頁」、「第 2 頁，共 12 頁」，依此類推。
這會取代原有的頁首或頁尾嗎？
不會——它會在頁面上方繪製新的文字；如果 PDF 該區域原本就有內容，兩者都會顯示。留空欄位即可略過該項目。
Can I add different text to the header versus the footer?
Yes — they're separate fields; fill in one, both, or leave either blank to skip it.
Can I control the font size or position more precisely?
The header sits at the top and footer at the bottom of each page, centered horizontally, in one built-in font and a neutral gray color — separate controls for font, size, color, or left/right alignment aren't available yet.
Will this overwrite an existing header or footer already on the page?
No — new text is drawn on top of the page. If there's already content in that area, both will be visible; leave a field blank to avoid adding anything there.
Can I add today's date automatically instead of typing it in?
No — only two placeholders are supported: {n} for the current page number and {total} for the total page count. There's no date or time token, so if you want today's date in the header or footer, type it in as plain text.
Does the header/footer skip the first page, or can I apply it to only some pages?
It's stamped on every page the same way, including the first one — there's no option to skip a page range or start numbering partway through yet.
