Question 1

How does the PDF Header & Footer Adder work?

Accepted Answer

Load a PDF, type your header/footer text, and choose positions (left/center/right), font size, color, and margins. The tool draws the text on each page using pdf-lib, substituting variables like {page}, {total}, {title}, {date}, {author}, and {filename} with their actual values. The modified PDF is saved and downloaded — 100% in your browser.

Question 2

What variables can I use in the header or footer text?

Accepted Answer

Six variables: {page} (current page number), {total} (total page count), {title} (PDF Title metadata), {date} (today's date in your chosen format), {author} (PDF Author metadata), and {filename} (original file name without extension). The tool warns you if a variable requires metadata that's missing from the PDF.

Question 3

Can I use different header/footer text on the first page?

Accepted Answer

Yes. Toggle 'First page different' and provide separate first-page header and footer text. This is useful for cover pages where you don't want a page number, or where you want a different title.

Question 4

What extra features does this tool have compared to others?

Accepted Answer

(1) Page-range parser ('all' or '1-3, 5, 8-'). (2) Variable substitutor ({page}/{total}/{title}/{date}/{author}/{filename}).

(11) Copy + Download. (12) History (localStorage, last 20). (13) Shareable URL. (14) Summary stats (pages with/without header/footer, by position). (15) Variable availability checker. (16) Header/footer collision detector. (17) Page count validator. Multi-line header/footer support included.

Question 5

Is my data sent anywhere?

Accepted Answer

No. All PDF processing runs 100% in your browser using JavaScript and pdf-lib. Your PDF never leaves your device, and the tool works offline. History is stored in localStorage on this device only.
