Why use Page Numbers in your browser?

PDFs often hold contracts, IDs, financial statements, or internal reports. Page Numbers: Stamp page numbers in any corner. Use <code>{n}</code> and <code>{total}</code> in the format. Server-side tools upload or log inputs. Just Tool It does not: it uses client-side PDF libraries (such as pdf-lib and PDF.js) that read files as ArrayBuffers in memory. Close the tab and the working data is gone. That is zero-server processing and on-device security.

Frequently asked questions

Is my data uploaded when I use Page Numbers?

No. Just Tool It is a static web app. Your input is processed with client-side PDF libraries (such as pdf-lib and PDF.js) that read files as ArrayBuffers in memory. You can verify in the browser Network panel: no file payloads are sent to our origin for processing.

Is this tool free? Do I need an account?

Yes, it is free. There is no sign-up, paywall, or trial. We do not create user accounts because we never receive your files.

Does it work offline?

After the page and any required libraries are cached (including via the service worker / PWA), many tools keep working without a network. Large optional engines such as FFmpeg.wasm or OCR models still need a one-time download.

How is this different from other free online tools?

Most free tools upload files to a cloud worker. Just Tool It emphasizes zero-server processing and on-device security: files stay in browser memory until you download the output and close the tab.
