Frequently asked questions
Is the Add Page Numbers tool free?
Yes. Every DigiToolkit PDF tool is completely free to use, with no sign-up and no watermarks added by us.
Are my files uploaded to a server?
No. The Add Page Numbers runs entirely inside your web browser using JavaScript. Your files never leave your computer, which keeps your documents private.
Do I need to install any software?
No. The add page numbers works in any modern browser on desktop or mobile — nothing to download or install.
Is there a file size limit?
There is no fixed limit, but because processing happens on your own device, very large files depend on your device's memory. A few hundred pages works fine on most computers.
Will using this tool reduce the quality of my PDF?
No quality is lost for page operations like merging, splitting, rotating, reordering and watermarking. Conversions and compression are noted on the page where quality may change.
Which browsers are supported?
Chrome, Edge, Firefox and Safari (recent versions) are all supported. A reasonably up-to-date browser is recommended.
Can I use the Add Page Numbers on my phone?
Yes, it is mobile-friendly. Some heavy operations are faster on a desktop, but the tool works on phones and tablets too.
Is it safe for confidential documents?
Yes. Because nothing is uploaded, sensitive documents stay on your device. For redaction, the content is permanently removed, not just hidden.
