Set PDF Page Labels - Free Online Browser Tool

Set Roman, decimal, alphabetic or prefixed viewer page labels without printing numbers on the page.

Reports often number introductory pages with Roman numerals and restart the main document at one. Page labels express that structure to supporting PDF viewers without adding ink to the page. Define physical start pages and numbering styles, load existing label ranges, or explicitly reset the document to standard numbering.

How to Use the Set PDF Page Labels Tool

Four steps, and the whole thing runs locally on your own device.

  1. Separate labels from printed numbers

    Decide whether you need viewer navigation or visible numbering. Add Page Numbers draws numbers on pages; this editor changes navigation labels only.

  2. Load the label ranges

    Select one PDF and load its existing labels. The editor reads the current number tree; malformed labels require an explicit replacement or reset decision.

  3. Describe each numbering section

    Keep the first range at physical page one. Add later starts, choose a numeric style and optional prefix, and review the range samples and duplicate-label warning.

  4. Save viewer numbering

    Process the validated ranges and open the labeled copy in a viewer that supports PDF page labels. Printed artwork and the physical page order are unchanged.

Frequently Asked Questions

Can two pages have the same label?

Yes, repeated labels are permitted and prefix-only sections intentionally repeat their prefix. A preview warning helps you avoid accidental ambiguity.

Does this print numbers at the bottom of pages?

No. Page labels are navigation metadata shown by supporting viewers. Use Add Page Numbers when the numbers need to appear in printed copies or page artwork.

Can the introduction use i and ii before page 1?

Yes. Start a lowercase Roman range at physical page one and a decimal range at the first body page. Set the decimal starting number to one.

What does resetting PDF labels do?

Reset removes the document page-label tree. Viewers then use their standard physical numbering rather than the custom Roman, alphabetic or prefixed labels.

Are custom labels supported by every viewer?

No. Some applications display physical page positions even when valid labels exist. The downloaded PDF retains the labels, but each viewer decides how to present navigation.
