Frequently Asked Questions
Is this tool secure to use with sensitive documents?
Yes. This is one of our most secure tools. All PDF processing for adding page numbers is done client-side, directly in your web browser, using the `pdf-lib` library. Your document is never uploaded to any external server, guaranteeing its privacy.
Can I start numbering from page 2?
Yes. Select the "Custom Range" option and set the "Start" page to 2. The tool will then apply numbers only from page 2 to the end of the document.
How can I format the page numbers like "1 / 10"?
In the "Format String" field, simply type {p} / {t}. The tool will automatically replace {p} with the current page number and {t} with the total number of pages.
What font options are available?
We use the standard PDF base fonts: Helvetica, Times-Roman, and Courier. These are guaranteed to work on all PDF readers without needing to embed large font files, keeping your PDF lightweight.
