About Add Page Numbers to PDF — Free Online Tool
Add Page Numbers to PDF stamps clear, sequential page numbers or "Page X of Y" counters directly onto your PDF document pages at chosen positions.
The engine parses the incoming PDF with pdf-lib, inspecting each page dimensions and orientation. It computes coordinate offsets for the requested placement (such as bottom-center or top-right) and draws numbers using the standard Helvetica font stream. You can customize the starting number offset, font size, and choose between single integer numbering or composite total counts. The modified document structure is reserialized with cross-reference tables preserved.
All PDF loading, font vectorization, coordinate placement, and document serialization are performed within client-side WebAssembly and JavaScript. No document pages or metadata are ever transmitted to an external server.
Numbering legal briefs and court exhibits before submission, preparing formal manuscript submissions, indexing multipage financial statements, and preparing printed handout packets.
