Small feature, real problem
Merged PDFs, scans, and exports from design tools routinely arrive with no page numbers — fine on screen, chaos the
moment someone prints twenty pages and drops them. "Page 4 of 20" in the footer fixes it in one pass, in the
typeface every document reader expects, without re-rendering a single page — the text is added as a real PDF layer,
so the document stays sharp and searchable.
The starting-number control handles the classic cover-page problem, and everything runs in your browser — a
numbered contract is still a contract, and it never leaves your device. Often paired with
Merge PDF (number after merging, so the count is right) and Sign
PDF.
Frequently asked questions
Which format should I use?
“Page 1 of 12” is the safest — anyone holding a printed page knows both where they are and whether pages are missing. Plain numbers suit books and theses where a style guide dictates the footer.
Can numbering start at something other than 1?
Yes — set the starting number. Starting at 2 (or 0) is the classic fix when a cover page shouldn’t count.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
