立即试用常见问题
Upload the PDF, choose the position (bottom center is the default), the format and the starting number — the live preview shows exactly where the number will sit — then download the numbered PDF.
usageYes — three formats are available: plain numbers (1, 2, 3), "Page 1", and "Page 1 of N" with the total filled in automatically.
featuresYes — set any starting number. Useful when the document is part of a larger set, or when an unnumbered cover page should keep page 1 for the content.
featuresSix positions: bottom or top, each in left, center or right. Font size is adjustable from 8 to 18pt, stamped in standard Helvetica.
featuresNo — numbering happens entirely in your browser with pdf-lib; the file never leaves your device. Merge PDFs first to number a combined document continuously.
privacyAdd Page Numbers 如何助您完成任务
它每天都在解决真实的问题——服务企业、创作者和日常任务。找到适合您的用例，几秒即可开始。
Number Court and Compliance Bundles
Legal filings and audit binders must cite exact pages — stamp continuous numbers on the merged bundle so references hold.
Paginate Reports and Theses
Add "Page N of M" to long documents so printed copies survive shuffling and reviewers can reference sections precisely.
Number Scanned Archives
Scanners output unnumbered pages — stamping them preserves document order in shared archives forever.
Skip the Cover Page
Start numbering at 0 or 2, or begin from any number, so a title page stays clean while content numbering matches the table of contents.
