Page labels change how readers number pages without altering page content — for example roman numerals for a preface and 1, 2, 3 for the body.
This tool runs entirely in your browser. Your file is read from your device, processed in memory, and saved back to your device — it is never uploaded to QPDF or anyone else. The first time you use it, your browser downloads the CoherentPDF engine (software only, about 9 MB) from qpdf.ca and keeps it for offline use.
