About Add Page Numbers to PDF
Merged documents, court bundles and printed handouts need running page numbers so readers can refer to a page — and the numbers baked into the file survive printing, unlike a viewer’s page counter.
Numbers are drawn as real text with an embedded standard font, so they stay crisp at any zoom and can be found with search.

About the format
PDF · Portable Document Format · .pdf
The fixed-layout document standard: looks the same on every device and printer, which is why forms, invoices, contracts and reports are shared as PDF.
- A PDF can contain vector text, embedded fonts, images, form fields, annotations and digital signatures.
- Scanned PDFs are just pictures of pages; they need OCR before the text can be searched or copied.
- PDF is an open ISO standard (ISO 32000) since 2008.
