Choose Page Number Position
Place numbers at the top or bottom, aligned left, center or right. Placement follows each page’s visible area and rotation. Font width determines centering and right alignment. Preview each relevant page, especially in mixed-size documents.
Skip the First Page
Leave a cover page unnumbered by turning on Skip First Page. This always excludes physical page 1. Custom ranges such as 2-5,8,10 are checked against the document; repeated pages receive one number, in document order.
Customize Page Numbers
Choose plain numbers, Page 1 labels or a fraction. Starting Number is a positive integer; the fraction denominator counts only numbered pages. Choose 8–24 pt Helvetica, a text color and margins in points. If any selected page cannot contain the complete label, reduce the margin or font size before trying again.
Privacy & Local Processing
A local worker adds PDF text objects without rasterizing the original pages. Only the current preview page is rendered. Workers, canvases and temporary URLs are released when finished or cancelled. PDF content and file names are not sent to analytics. Signed PDFs are rejected because modification can invalidate signatures; review forms and other special structures in your downloaded copy.
BEFORE YOU START
Add Page Numbers to PDF: common questions
How does Skip First Page work?
It excludes physical page 1, even with a custom range. With Starting Number 1, the next selected page receives 1. Selected pages are numbered in document order, with duplicates counted once.
What does the total in 1 / 10 mean?
The denominator is the number of pages actually receiving a number, after applying the range and skipping the first page. Starting Number changes only the numerator. For example, selecting three pages and starting at 5 produces 5 / 3, 6 / 3 and 7 / 3.
Will my PDF become a picture?
No. Page numbers are added as PDF text objects. Existing selectable text, vectors and links are retained where supported. Forms, bookmarks, tags, annotations and special structures are not guaranteed; review the downloaded document.
Can I number a signed or password-protected PDF?
Encrypted PDFs and detectable digital signatures or certifications are rejected. Editing can invalidate signatures. Use an unsigned, unencrypted copy that you are authorized to edit; passwords are not bypassed.
Which pages and fonts are supported?
Mixed sizes, A4, Letter, portrait, landscape and rotations in 90-degree steps are supported. Number positions use the visible CropBox and MediaBox intersection. Helvetica supports the basic Latin numbering styles; custom non-Latin labels are not offered.
Are there file limits or uploads?
Processing stays in your browser, with no PDF upload. The limit is 64 MB and 50 pages, with stricter memory limits on some devices. Excessive margins or numbers that do not fit are rejected. File names and PDF content are not sent to analytics.
