Drag your PDFs onto the upload box — or drop a whole folder, or use "Choose folder" to pick one. The tool adds each PDF to the list, then click "Apply to all". Every file is numbered one by one, and when it finishes you click "Download ZIP" to get them all in a single archive.
No. This is a 100% client-side tool — every PDF is opened and numbered right inside your browser, and nothing is sent to any server. Your files never leave your device, which is why it works even on confidential documents.
You get one ZIP file (named dockdocs-batch.zip) containing every successfully numbered PDF. Each output keeps its original name with a "-numbered.pdf" suffix added — so report.pdf becomes report-numbered.pdf. Only files that processed successfully are included; any that failed are skipped and the rest still come through.
You can process up to 30 PDFs per batch — the counter next to the list shows how many you've added (for example "12 / 30 files"). There's no hard size limit, but since everything runs in your browser, very large or numerous files use more memory and run slower on weaker devices. You can safely drop a folder that also contains images or Word docs: the tool automatically keeps only the actual PDFs and filters everything else out.
Not in the batch tool — it uses a fixed default placement to keep the whole folder consistent in one click. If you need to control the position, font, or starting number, use the single-file "Add page numbers" tool instead, which gives you those options.
It's completely free with no signup required, and there's no watermark added to your PDFs. Because everything runs locally in your browser, there's nothing to pay for and no upload quota.
This tool runs entirely in your browser. Your file never leaves your device — it isn't uploaded to any server.
Check for yourself: open your browser's developer tools (F12, or right-click → Inspect) → the Network tab → then run this tool. You won't see your file uploaded anywhere, because the work happens locally on your device.
