Frequently asked
Is my PDF uploaded to a server?
No. Add Page Numbers to PDF runs entirely in your browser using pdf-lib and PDF.js compiled for the browser. Your PDF never leaves your device and we don’t store anything.
Which formats are supported?
Standard PDF files of any version. Password-protected PDFs need to be unlocked first.
Is there a file size limit?
We don’t impose one. Very large PDFs (hundreds of MB) depend on your browser’s available memory.
Is Page Numbers free? Do I need an account?
Yes, it is completely free and there is no account, sign-up or watermark. It is one of 78 free browser tools from ModelsGroup.
Does it work on my phone?
Yes. It works in Safari and Chrome on iPhone, iPad and Android; open PDFs from Files or your downloads.
