Free Online PDF Page Number Adder — Full Customization with Live Preview

InstantToolsPro's Add Page Numbers tool gives you complete control over how page numbers appear on your PDF. Choose from six position presets (top/bottom × left/center/right), five built-in number formats, or create your own with {n} and {t} placeholders. Adjust font family, size, color, bold/italic, opacity, and margins from the real-time settings panel — every change reflects instantly on all page thumbnails without a single server request.

The tool uses Ghostscript's PostScript overlay engine, injecting a pre-computed number list for each page for maximum accuracy. Skip cover pages, start numbering from any value, apply numbers to odd pages, even pages, or a custom range. All files are deleted after one hour. No account required.
